INTRODUCTION

Dear customer!

Congratulations on your choice to buy a Husqvarna product! Husqvarna is based on a tradition that dates back to 1689, when the Swedish King Karl XI ordered the construction of a factory on the banks of the Huskvarna River, for production of muskets. The location was logical, since water power was harnessed from the Huskvarna River to create the waterpowered plant. During over 300 years of continuous operation, the Husqvarna factory has produced a lot of different products, from wood stoves to modern kitchen appliances, sewing machines, bicycles, motorcycles etc. In 1956, the rst motor driven lawn mowers appeared, followed by chain saws in 1959, and it is within this area Husqvarna is working today. Today Husqvarna is one of the leading manufacturers in the world of forest and garden products, with quality as our highest priority. We develop, manufacture and market high quality motor driven products for forestry and gardening as well as for building and construction industry. Your purchase gives you access to professional help with repairs and service whenever this may be necessary. If the retailer who sells your machine is not one of our authorized dealers, ask for the address of your nearest servicing dealer. It is our wish that you will be satised with your product and that it will be your companion for a long time. Think of this operators manual as a valuable document. By following its content (using, service, maintenance etc) the life span and the second-hand value of the machine can be extended. If you ever lend or sell this machine, make sure that the borrower or buyer gets the operators manual, so they will also know how to properly maintain and use it. Thank you for using a Husqvarna product. Husqvarna AB has a policy of continuous product development and therefore reserves the right to modify the design and appearance of products without prior notice.

GENERAL SAFETY PRECAUTIONS

Important

IMPORTANT! The machine is only designed for trimming grass, grass clearing and/or forestry clearing. The only accessories you can operate with this engine unit are the cutting attachments we recommend in the chapter on Technical data. Never use the machine if you are tired, if you have drunk alcohol, or if you are taking medication that could affect your vision, your judgement or your co-ordination. Wear personal protective equipment. See instructions under the heading Personal protective equipment. Never use a machine that has been modied in any way from its original specication. Never use a machine that is faulty. Carry out the checks, maintenance and service instructions described in this manual. Some maintenance and service measures must be carried out by trained and qualied specialists. See instructions under the heading Maintenance. All covers, guards and handles must be tted before starting. Ensure that the spark plug cap and ignition lead are undamaged to avoid the risk of electric shock. The machine operator must ensure that no people or animals come closer than 15 metres while working. When several operators are working in the same area the safety distance should be at least twice the tree height and no less than 15 metres. WARNING! This machine produces an electromagnetic eld during operation. This eld may under some circumstances interfere with active or passive medical implants. To reduce the risk of serious or fatal injury, we recommend persons with medical implants to consult their physician and the medical implant manufacturer before operating this machine. WARNING! Running an engine in a conned or badly ventilated area can result in death due to asphyxiation or carbon monoxide poisoning. GLOVES Gloves should be worn when necessary, e.g., when tting cutting attachments.

Personal protective equipment
IMPORTANT! A clearing saw, brushcutter or trimmer can be dangerous if used incorrectly or carelessly, and can cause serious or fatal injury to the operator or others. It is extremely important that you read and understand the contents of this operators manual. You must use approved personal protective equipment whenever you use the machine. Personal protective equipment cannot eliminate the risk of injury but it will reduce the degree of injury if an accident does happen. Ask your dealer for help in choosing the right equipment. WARNING! Listen out for warning signals or shouts when you are wearing hearing protection. Always remove your hearing protection as soon as the engine stops.

HELMET

A helmet should be worn if the trees being cleared are taller than 2 m.
HEARING PROTECTION Wear hearing protection that provides adequate noise reduction.
EYE PROTECTION Always wear approved eye protection. If you use a visor then you must also wear approved protective goggles. Approved protective goggles must comply with standard ANSI Z87.1 in the USA or EN 166 in EU countries.

6 English

BOOTS Wear boots with steel toe-caps and non-slip sole.

Throttle lockout

The throttle lockout is designed to prevent accidental operation of the throttle control. When you press the lock (A) (i.e. when you grasp the handle) it releases the throttle control (B). When you release the handle the throttle control and the throttle lockout both move back to their original positions. This movement is controlled by two independent return springs. This arrangement means that the throttle control is automatically locked at the idle setting.
CLOTHING Wear clothes made of a strong fabric and avoid loose clothing that can catch on twigs and branches. Always wear heavy, long pants. Do not wear jewellery, shorts sandals or go barefoot. Secure hair so it is above shoulder level. FIRST AID KIT Always have a rst aid kit nearby.
Make sure the throttle control is locked at the idle setting when the throttle lockout is released.

Stop switch

Use the stop switch to switch off the engine. Use of incorrectly wound cord or an incorrect cutting attachment increases the level of vibration. See instructions under the heading Cutting equipment. The machines vibration damping system reduces the transfer of vibration between the engine unit/cutting equipment and the machines handle unit.
Start the engine and make sure the engine stops when you move the stop switch to the stop setting.

Cutting attachment guard

Regularly check the vibration damping units for cracks or deformation. Check that the vibration damping element is undamaged and securely attached. This guard is intended to prevent loose objects from being thrown towards the operator. The guard also protects the operator from accidental contact with the cutting attachment.
WARNING! Overexposure to vibration can lead to circulatory damage or nerve damage in people who have impaired circulation. Contact your doctor if you experience symptoms of overexposure to vibration. Such symptoms include numbness, loss of feeling, tingling, pricking, pain, loss of strength, changes in skin colour or condition. These symptoms normally appear in the ngers, hands or wrists. The risk increases at low temperatures.
Check that the guard is undamaged and not cracked. Replace the guard if it has been exposed to impact or is cracked. Always use the recommended guard for the cutting attachment you are using. See chapter on Technical data.

Quick release

There is an easily accessible, quick release tted at the front as a safety precaution in case the engine catches re, or in any other situation that requires you to free yourself from the machine and harness. See instructions under the heading Adjusting the harness and brush
WARNING! Never use a cutting attachment without an approved guard. See the chapter on Technical data. If an incorrect or faulty guard is tted this can cause serious personal injury.

cutter. Certain harnesses also have a quick release tted to the support hook. Regularly check that the mufer is securely attached to the machine.
Check that the harness straps are correctly positioned. Once the harness and machine have been adjusted, check that the harness quick release works correctly.

If the mufer on your machine is tted with a spark arrestor screen this must be cleaned regularly. A blocked screen will cause the engine to overheat and may lead to serious damage.
The mufer is designed to keep noise levels to a minimum and to direct exhaust fumes away from the user. A mufer tted with a catalytic converter is also designed to reduce harmful exhaust gases.
WARNING! Mufers tted with catalytic converters get very hot during use and remain so for some time after stopping. This also applies at idle speed. Contact can result in burns to the skin. Remember the risk of re! WARNING! The inside of the mufer contain chemicals that may be carcinogenic. Avoid contact with these elements in the event of a damaged mufer. WARNING! Bear in mind that: The exhaust fumes from the engine are hot and may contain sparks which can start a re. Never start the machine indoors or near combustible material!
In countries that have a warm and dry climate there is a signicant risk of re. We therefore t certain mufers with a spark arrestor screen. Check whether the mufer on your machine is tted with this kind of screen.

Locking nut

For mufers it is very important that you follow the instructions on checking, maintaining and servicing your machine. Never use a machine that has a faulty mufer.
A locking nut is used to secure some types of cutting attachment. When tting, tighten the nut in the opposite direction to the direction of rotation of the cutting attachment. To remove it, undo the nut in the same direction as the cutting attachment rotates. (CAUTION! The nut has a left-hand thread.) When loosening and tightening the saw blade nut, there is a risk of injury from the teeth of the saw blade. You should therefore always ensure that your hand is shielded by the blade guard when doing this. Always use a socket spanner with a shaft that is long enough to allow this. The arrow in the diagram shows the area where you

English 9

should operate the socket spanner when loosening or tightening the nut.

Cutting equipment

Saw blades are intended for cutting brous types of wood.
Grass blades and grass cutters are intended for cutting coarse grass. The nylon lining inside the locking nut must not be so worn that you can turn it by hand. The lining should offer a resistance of at least 1.5 Nm. The nut should be replaced after it has been put on approx. 10 times.
This section describes how to choose and maintain your cutting equipment in order to: Reduce the risk of blade thrust. Obtain maximum cutting performance. Extend the life of cutting equipment. IMPORTANT! Only use cutting attachments with the guards we recommend! See the chapter on Technical data. Refer to the instructions for the cutting attachment to check the correct way to load the cord and the correct cord diameter. Keep the teeth of the blade correctly sharpened! Follow our recommendations. Also refer to the instructions on the blade packaging. Maintain the correct blade setting! Follow our instructions and use the recommended le gauge. WARNING! Always stop the engine before doing any work on the cutting attachment. This continues to rotate even after the throttle has been released. Ensure that the cutting attachment has stopped completely and disconnect the HT lead from the spark plug before you start to work on it. WARNING! Using an incorrect cutting attachment or an incorrectly sharpened blade increases the risk of blade thrust.

Smaller machines generally require small trimmer heads and vice versa. This is because when clearing using a cord the engine must throw out the cord radially from the trimmer head and overcome the resistance of the grass being cleared. The length of the cord is also important. A longer cord requires greater engine power than a shorter cord of the same diameter. Make sure that the cutter on the trimmer guard is intact. This is used to cut the cord to the correct length. To increase the life of the cord it can be soaked in water for a couple of days. This will make the line tougher so that it lasts longer.

English 13

Assembling the cutting equipment
Turn the blade shaft until one of the holes in the drive disc aligns with the corresponding hole in the gear housing. Insert the locking pin (C) in the hole to lock the shaft. Place the blade (D), support cup (E) and support ange (F) on the output shaft. Fit the nut (G). The nut must be tightened to a torque of 35-50 Nm (3.5-5 kpm). Use the socket spanner in the tool kit. Hold the shaft of the spanner as close to the blade guard as possible. To tighten the nut, turn the spanner in the opposite direction to the direction of rotation (Caution! left-hand thread).
WARNING! When tting the cutting attachment it is extremely important that the raised section on the drive disc/ support ange engages correctly in the centre hole of the cutting attachment. If the cutting attachment is tted incorrectly it can result in serious and/or fatal personal injury.

When loosening and tightening the saw blade nut, there is a risk of injury from the teeth of the saw blade. You should therefore always ensure that your hand is shielded by the blade guard when doing this. Always use a socket spanner with a shaft that is long enough to allow this. The arrow in the diagram shows the area
Tighten the trimmer head to a torque of 35-50 Nm (3.5-5 kpm). To dismantle, follow the instructions in the reverse order.

English 15

Fitting other guards and cutting attachments Adjusting the harness and brush cutter
Fit the trimmer guard/combination guard (A) intended for use with the trimmer head/plastic blades. CAUTION! Ensure that the guard extension is tted. Hang the trimmer guard/combination guard (A) on the two hooks on the plate holder (M). Bend the guard around the shaft and tighten it with the bolt (L) on the opposite side of the shaft. Use the locking pin (C). Place the locking pin in the groove on the screw head and tighten. See diagram.
WARNING! When using a brush cutter it must always be hooked securely to the harness. Otherwise you will be unable to control the brush cutter safely and this can result in injury to yourself or others. Never use a harness with a defective quick release.
At the front is an easily accessible, quick release. Use this if the engine catches re or in any other emergency situation that requires you to free yourself from the machine and harness.
Fit the drive disc (B) on the output shaft. Turn the blade shaft until one of the holes in the drive disc aligns with the corresponding hole in the gear housing. Insert the locking pin (C) in the hole to lock the shaft. Screw on the trimmer head/plastic blades (H) in the opposite direction to the direction of rotation.
Spreading the load on your shoulders
A well-adjusted harness and machine makes work much easier. Adjust the harness for the best working position. Tension the side straps so that the weight is evenly distributed across both shoulders.
To dismantle, follow the instructions in the reverse order.

16 English

Correct height
1 Forestry clearing Adjust the support strap so that the support hook is around 10 cm below your hip. The blade should be angled forward a little. 2 Grass clearing The support hook should hang around 20 cm below your hip so that the blade is parallel to the ground.

Correct balance

1 Forestry clearing Move the suspension ring on the machine forward or backward. It is easier to avoid sawing into the ground if the blade is balanced a few dm above the ground. 2 Grass clearing Let the blade balance at a comfortable cutting height, i.e. close to the ground.

Two-stroke oil

For best results and performance use HUSQVARNA two-stroke engine oil, which is specially formulated for our air-cooled two stroke-engines. Never use two-stroke oil intended for water-cooled engines, sometimes referred to as outboard oil (rated TCW). Never use oil intended for four-stroke engines. Mixing ratio 1:50 (2%) with HUSQVARNA two-stroke oil. Gasoline, litre US gallon 1/Two-stroke oil, litre 2% (1:50) 0,10 0,20 0,30 0,40 US. oz. 2 1/1/7/8
CAUTION! The machine is equipped with a two-stroke engine and must always been run using a mixture of gasoline and two-stroke engine oil. It is important to accurately measure the amount of oil to be mixed to ensure that the correct mixture is obtained. When mixing small amounts of fuel, even small inaccuracies can drastically affect the ratio of the mixture.
WARNING! Fuel and fuel fumes are highly inammable and can cause serious injury when inhaled or allowed to come in contact with the skin. For this reason observe caution when handling fuel and make sure there is adequate ventilation.

18 English

Mixing
Always mix the gasoline and oil in a clean container intended for fuel. Always start by lling half the amount of the gasoline to be used. Then add the entire amount of oil. Mix (shake) the fuel mixture. Add the remaining amount of gasoline. Mix (shake) the fuel mixture thoroughly before lling the machines fuel tank.

Fueling

WARNING! Taking the following precautions, will lessen the risk of re: Do not smoke or place hot objects near fuel. Always shut off the engine before refuelling. Always stop the engine and let it cool for a few minutes before refuelling. When refuelling, open the fuel cap slowly so that any excess pressure is released gently. Tighten the fuel cap carefully after refuelling. Always move the machine away from the refuelling area before starting.
Do not mix more than one months supply of fuel at a time. If the machine is not used for some time the fuel tank should be emptied and cleaned.
Clean the area around the fuel cap. Contamination in the tank can cause operating problems. Ensure that the fuel is well mixed by shaking the container before lling the tank.
WARNING! The catalytic converter mufer gets very hot during and after use. This also applies during idling. Be aware of the re hazard, especially when working near ammable substances and/ or vapours.

English 19

STARTING AND STOPPING

Check before starting

trimmer guard if they have been exposed to impact or are cracked.
Check the blade to ensure that no cracks have formed at the bottom of the teeth or by the centre hole. The most common reason why cracks are formed is that sharp corners have been formed at the bottom of the teeth while sharpening or that the blade has been used with dull teeth. Discard a blade if cracks are found. Never use the machine without a guard nor with a defective guard. All covers must be correctly tted and undamaged before you start the machine.

Primer bulb: Press the air purge repeatedly until fuel begins to ll the bulb. The bulb need not be completely lled.

Stopping

Starting
WARNING! When the engine is started with the choke in either the choke or start throttle positions the cutting attachment will start to rotate immediately.
Stop the engine by switching off the ignition.
Hold the body of the machine on the ground using your left hand (CAUTION! Not with your foot!). Grip the starter handle, slowly pull out the cord with your right hand until you feel some resistance (the starter pawls grip), now quickly and powerfully pull the cord.

WORKING TECHNIQUES
General working instructions
IMPORTANT! This section describes the basic safety precautions for working with brush cutters and trimmers. If you encounter a situation where you are uncertain how to proceed you should ask an expert. Contact your dealer or your service workshop. Avoid all usage which you consider to be beyond your capability. You must understand the difference between forestry clearing, grass clearing and grass trimming before use. Keep a good balance and a rm foothold. Always hold the machine with both hands. Hold the machine on the right side of your body. position yourself incorrectly or make the cut in the wrong place the tree may hit you or the machine and cause you to lose control. Both situations can cause serious personal injury.

Basic safety rules

Look around you: To ensure that people, animals or other things cannot affect your control of the machine. To ensure that people, animals, etc., do not come into contact with the cutting attachment or loose objects that are thrown out by the cutting attachment. CAUTION! Do not use the machine unless you are able to call for help in the event of an accident. Inspect the working area. Remove all loose objects, such as stones, broken glass, nails, steel wire, string, etc. that could be thrown out or become wrapped around the cutting attachment. Do not use the machine in bad weather, such as dense fog, heavy rain, strong wind, intense cold, etc. Working in bad weather is tiring and often brings added risks, such as icy ground, unpredictable felling direction, etc. Make sure you can move and stand safely. Check the area around you for possible obstacles (roots, rocks, branches, ditches, etc.) in case you have to move suddenly. Take great care when working on sloping ground.

When cutting and sweeping you should use full throttle to obtain the best results.

26 English

MAINTENANCE

Carburetor

Your Husqvarna product has been designed and manufactured to specications that reduce harmful emissions. After the engine has used 8-10 tanks of fuel the engine will be run-in. To ensure that it continues to run at peak performance and to minimise harmful exhaust emissions after the running-in period, ask your dealer/ service workshop (who will have a rev counter at their disposal) to adjust your carburettor. the optimal setting and should be maintained for the rst few hours the machine is in use. The carburettor should then be nely adjusted. Fine adjustment should be carried out by a skilled technician. CAUTION! If the cutting attachment rotates when the engine is idling the idle adjustment screw T should be turned anti-clockwise until the cutting attachment stops.
Adjustment of the idle speed
Before any adjustments are made, make sure that the air lter is clean and the air lter cover is tted. Adjust the idle speed using the idle adjustment screw T, if it is necessary to readjust. First turn the idle adjustment screw T clockwise until the cutting attachment starts to rotate. Then turn the screw anticlockwise until the cutting attachment stops. The idle speed is correctly adjusted when the engine will run smoothly in every position. The idle speed should also be well below the speed at which the cutting attachment starts to rotate.

Function

The carburetor governs the engines speed via the throttle control. Air and fuel are mixed in the carburetor. The air/fuel mixture is adjustable. Correct adjustment is essential to get the best performance from the machine. The setting of the carburetor means that the engine is adapted to local conditions, for example, the climate, altitude, fuel and the type of 2-stroke oil. The carburetor has three adjustment controls: L = Low speed jet H = High speed jet T = Idle adjustment screw
Rec. idle speed: See the Technical data section.
WARNING! If the idle speed cannot be adjusted so that the cutting attachment stops, contact your dealer/service workshop. Do not use the machine until it has been correctly adjusted or repaired.

Bevel gear

The bevel gear is lled with the right quantity of grease at the factory. However, before using the machine you should check that the bevel gear is lled three-quarters full with grease. Use HUSQVARNA special grease.

28 English

The grease in the bevel gear does not normally need to be changed except if repairs are carried out. use common engine oil. This would drain through the lter quite quickly and collect in the bottom.

Air lter

The air lter must be regularly cleaned to remove dust and dirt in order to avoid: Carburettor malfunctions Starting problems Loss of engine power Unnecessary wear to engine parts Excessive fuel consumption. The spark plug condition is inuenced by: Incorrect carburetor adjustment. An incorrect fuel mixture (too much or incorrect type of oil). A dirty air lter.

Spark plug

These factors cause deposits on the spark plug electrodes, which may result in operating problems and starting difculties. Clean the lter every 25 hours, or more regularly if conditions are exceptionally dusty. If the machine is low on power, difcult to start or runs poorly at idle speed: always check the spark plug rst before taking any further action. If the spark plug is dirty, clean it and check that the electrode gap is 0.020 inch (0.5 mm). The spark plug should be replaced after about a month in operation or earlier if necessary.

Cleaning the air lter

Remove the air lter cover and take out the lter. Wash it clean in warm, soapy water. Ensure that the lter is dry before retting it. An air lter that has been in use for a long time cannot be cleaned completely. The lter must therefore be replaced with a new one at regular intervals. A damaged air lter must always be replaced. If the machine is used in dusty conditions the air lter should be soaked in oil. See instructions under the heading Oiling the air lter.

Oiling the air lter

CAUTION! Always use the recommended spark plug type! Use of the wrong spark plug can damage the piston/ cylinder. Check that the spark plug is tted with a suppressor. Note: Use only HUSQVARNA replacement parts. Use of other brands of replacement parts can cause damage to your unit or injury to the operator or others. Your warranty does not cover damage or liability caused by the use of accessories and/or attachments not specically recommended by HUSQVARNA.
Always use HUSQVARNA lter oil, art. no. 92-48. The lter oil contains a solvent to make it spread evenly through the lter. You should therefore avoid skin contact. Put the lter in a plastic bag and pour the lter oil over it. Knead the plastic bag to distribute the oil. Squeeze the excess oil out of the lter inside the plastic bag and pour off the excess before tting the lter to the machine. Never

be checked. See instructions under the heading Maintenance.

Vibration damping system

Your machine is equipped with a vibration damping system that is designed to minimize vibration and make operation easier.

Stop switch

Use the stop switch to switch off the engine. Use of incorrectly wound cord or an incorrect cutting attachment increases the level of vibration. See instructions under the heading Cutting equipment. The machines vibration damping system reduces the transfer of vibration between the engine unit/cutting equipment and the machines handle unit.
Start the engine and make sure the engine stops when you move the stop switch to the stop setting.

Cutting attachment guard

Regularly check the vibration damping units for cracks or deformation. Check that the vibration damping element is undamaged and securely attached. This guard is intended to prevent loose objects from being thrown towards the operator. The guard also protects the operator from accidental contact with the cutting attachment.
WARNING! Overexposure to vibration can lead to circulatory damage or nerve damage in people who have impaired circulation. Contact your doctor if you experience symptoms of overexposure to vibration. Such symptoms include numbness, loss of feeling, tingling, pricking, pain, loss of strength, changes in skin colour or condition. These symptoms normally appear in the ngers, hands or wrists. The risk increases at low temperatures.
Check that the guard is undamaged and not cracked. Replace the guard if it has been exposed to impact or is cracked. Always use the recommended guard for the cutting attachment you are using. See chapter on Technical data.

Quick release

Saw blades are intended for cutting brous types of wood.
Grass blades and grass cutters are intended for cutting coarse grass. The nylon lining inside the locking nut must not be so worn that you can turn it by hand. The lining should offer a resistance of at least 1.5 Nm. The nut should be replaced after it has been put on approx. 10 times.
This section describes how to choose and maintain your cutting equipment in order to: Reduce the risk of blade thrust. Obtain maximum cutting performance. Extend the life of cutting equipment. IMPORTANT! Only use cutting attachments with the guards we recommend! See the chapter on Technical data. Refer to the instructions for the cutting attachment to check the correct way to load the cord and the correct cord diameter. Keep the teeth of the blade correctly sharpened! Follow our recommendations. Also refer to the instructions on the blade packaging. Maintain the correct blade setting! Follow our instructions and use the recommended le gauge. WARNING! Always stop the engine before doing any work on the cutting attachment. This continues to rotate even after the throttle has been released. Ensure that the cutting attachment has stopped completely and disconnect the HT lead from the spark plug before you start to work on it. WARNING! Using an incorrect cutting attachment or an incorrectly sharpened blade increases the risk of blade thrust.

Two-stroke oil

For best results and performance use HUSQVARNA two-stroke engine oil, which is specially formulated for our air-cooled two-stroke engines. Never use two-stroke oil intended for water-cooled engines, sometimes referred to as outboard oil (rated TCW). Never use oil intended for four-stroke engines. A poor oil quality and/or too high oil/fuel ratio may jeopardise function and decrease the life time of catalytic converters. Mixing ratio 1:50 (2%) with HUSQVARNA two-stroke oil. 1:33 (3%) with oils class JASO FB or ISO EGB formulated for air-cooled, two-stroke engines. Petrol, litre Two-stroke oil, litre 2% (1:50) 0,10 0,20 0,30 0,40 3% (1:33) 0,15 0,30 0,45 0,60
WARNING! Take care when handling fuel. Bear in mind the risk of re, explosion and inhaling fumes.
CAUTION! The machine is equipped with a two-stroke engine and must always been run using a mixture of petrol and two-stroke oil. It is important to accurately measure the amount of oil to be mixed to ensure that the correct mixture is obtained. When mixing small amounts of fuel, even small inaccuracies can drastically affect the ratio of the mixture.
WARNING! Fuel and fuel fumes are highly inammable and can cause serious injury when inhaled or allowed to come in contact with the skin. For this reason observe caution when handling fuel and make sure there is adequate ventilation.

English 21

Mixing
Always mix the petrol and oil in a clean container intended for fuel. Always start by lling half the amount of the petrol to be used. Then add the entire amount of oil. Mix (shake) the fuel mixture. Add the remaining amount of petrol. Mix (shake) the fuel mixture thoroughly before lling the machines fuel tank.

Fuelling

WARNING! Taking the following precautions, will lessen the risk of re: Do not smoke or place hot objects near fuel. Always shut off the engine before refuelling. Always stop the engine and let it cool for a few minutes before refuelling. When refuelling, open the fuel cap slowly so that any excess pressure is released gently. Tighten the fuel cap carefully after refuelling. Always move the machine away from the refuelling area before starting.

Do not mix more than one months supply of fuel at a time. If the machine is not used for some time the fuel tank should be emptied and cleaned.
Always use a fuel container with an anti-spill valve. Clean the area around the fuel cap. Contamination in the tank can cause operating problems. Ensure that the fuel is well mixed by shaking the container before lling the tank.
WARNING! The catalytic converter mufer gets very hot during and after use. This also applies during idling. Be aware of the re hazard, especially when working near ammable substances and/ or vapours.

STARTING AND STOPPING

Check before starting

trimmer guard if they have been exposed to impact or are cracked.
Check the blade to ensure that no cracks have formed at the bottom of the teeth or by the centre hole. The most common reason why cracks are formed is that sharp corners have been formed at the bottom of the teeth while sharpening or that the blade has been used with dull teeth. Discard a blade if cracks are found. Never use the machine without a guard nor with a defective guard. All covers must be correctly tted and undamaged before you start the machine.

Starting and stopping

Check that the support ange is not cracked due to fatigue or due to being tightened too much. Discard the support ange if it is cracked. WARNING! The complete clutch cover and shaft must be tted before the machine is started, otherwise the clutch can come loose and cause personal injury. Always move the machine away from the refuelling area before starting. Place the machine on a at surface. Ensure the cutting attachment cannot come into contact with any object. Make sure no unauthorised persons are in the working area, otherwise there is a risk of serious personal injury. The safety distance is 15 metres.
Ensure the locking nut has not lost its captive force. The nut lock should have a locking force of at least 1.5 Nm. The tightening torque of the locking nut should be 35-50 Nm.
Check that the blade guard is not damaged or cracked. Replace the blade guard if it is exposed to impact or is cracked.

WORKING TECHNIQUES

General working instructions
IMPORTANT! This section describes the basic safety precautions for working with clearing saws and trimmers. If you encounter a situation where you are uncertain how to proceed you should ask an expert. Contact your dealer or your service workshop. Avoid all usage which you consider to be beyond your capability. You must understand the difference between forestry clearing, grass clearing and grass trimming before use. Keep a good balance and a rm foothold. Always hold the machine with both hands. Hold the machine on the right side of your body. yourself incorrectly or make the cut in the wrong place the tree may hit you or the machine and cause you to lose control. Both situations can cause serious personal injury.

Basic safety rules

Look around you: To ensure that people, animals or other things cannot affect your control of the machine. To ensure that people, animals, etc., do not come into contact with the cutting attachment or loose objects that are thrown out by the cutting attachment. CAUTION! Do not use the machine unless you are able to call for help in the event of an accident. Inspect the working area. Remove all loose objects, such as stones, broken glass, nails, steel wire, string, etc. that could be thrown out or become wrapped around the cutting attachment. Do not use the machine in bad weather, such as dense fog, heavy rain, strong wind, intense cold, etc. Working in bad weather is tiring and often brings added risks, such as icy ground, unpredictable felling direction, etc. Make sure you can move and stand safely. Check the area around you for possible obstacles (roots, rocks, branches, ditches, etc.) in case you have to move suddenly. Take great care when working on sloping ground.

Clear a strip around 75 m long. Move your fuel can as work progresses. On sloping ground you should work along the slope. It is much easier to work along a slope than it is to work up and down it. You should plan the strip so that you avoid going over ditches or other obstacles on the ground. You should also orient the strip to take advantage of wind

26 English

conditions, so that cleared stems fall in the cleared area of the stand. 3 oclock and 5 oclock so that the direction of rotation of the blade pushes the bottom of the tree to the left.
Forestry clearing using a saw blade
To fell a tree forwards, the bottom of the tree should be pulled backwards. Pull the blade backwards with a quick, rm movement.
The risk of blade thrust increases with increasing stem size. You should therefore avoid cutting with the area of the blade between 12 o'clock and 3 o'clock. Large stems must be cut from two sides. First determine which direction the stem will fall. Make the rst cut on the felling side. Then nish cutting the stem from the other side. Adjust the cutting pressure to match the size of the stem and the hardness of the wood. Small stems require more pressure, while large stems require less pressure.
To fell to the left, the bottom of the tree should be pushed to the right. Tilt the blade and bring it diagonally down to the right, exerting rm pressure. At the same time push the stem using the blade guard. Cut with the area of the blade between 3 oclock and 5 oclock. Apply full throttle before advancing the blade.
To fell to the right, the bottom of the tree should be pushed to the left. Tilt the blade and bring it diagonally up to the right. Cut with the area of the blade between
If the stems are tightly packed, adapt your walking pace to suit. If the blade jams in a stem, never jerk the machine free. If you do this the blade, bevel gear, shaft or handlebar may be damaged. Release the handles, grip the shaft with both hands and gently pull the machine free.

English 27

Brush cutting with a saw blade
Try to work rhythmically. Stand rmly with your feet apart. Move forward after the return stroke and stand rmly again. Let the support cup rest lightly against the ground. It is used to protect the blade from hitting the ground. Reduce the risk of material wrapping around the blade by following these instructions: 1Always work at full throttle. 2Avoid the previously cut material during the return stroke. Stop the engine, unclip the harness and place the machine on the ground before you start to collect the cut material.
Thin stems and brush are mown down. Work with a sawing movement, swinging sideways. Try to cut several stems in a single sawing movement. With groups of hardwood stems, rst clear around the group. Start by cutting the stems high up around the outside of the group to avoid jamming. Then cut the stems to the required height. Now try to reach in with the blade and cut from the centre of the group. If it is still difcult to gain access, cut the stems high up and let them fall. This will reduce the risk of jamming.

Grass trimming with a trimmer head
Trimming Hold the trimmer head just above the ground at an angle. It is the end of the cord that does the work. Let the cord work at its own pace. Never press the cord into the area to be cut.
Grass clearing using a grass blade
The cord can easily remove grass and weeds up against walls, fences, trees and borders, however it can also damage sensitive bark on trees and bushes, and damage fence posts. Reduce the risk of damaging plants by shortening the cord to 10-12 cm and reducing the engine speed.
Grass blades and grass cutters must not be used on woody stems. A grass blade is used for all types of tall or coarse grass. The grass is cut down with a sideways, swinging movement, where the movement from right-to-left is the clearing stroke and the movement from left-toright is the return stroke. Let the left-hand side of the blade (between 8 and 12 oclock) do the cutting.
Clearing The clearing technique removes all unwanted vegetation. Keep the trimmer head just above the ground and tilt it. Let the end of the cord strike the ground around trees, posts, statues and the like. CAUTION! This technique increases the wear on the cord.
If the blade is angled to the left when clearing grass, the grass will collect in a line, which makes it easier to collect, e.g. by raking.
The cord wears quicker and must be fed forward more often when working against stones, brick, concrete, metal fences, etc., than when coming into contact with trees and wooden fences. When trimming and clearing you should use less than full throttle so that the cord lasts longer and to reduce the wear on the trimmer head.

28 English

Cutting The trimmer is ideal for cutting grass that is difcult to reach using a normal lawn mower. Keep the cord parallel to the ground when cutting. Avoid pressing the trimmer head against the ground as this can ruin the lawn and damage the tool.
Do not allow the trimmer head to constantly come into contact with the ground during normal cutting. Constant contact of this type can cause damage and wear to the trimmer head.
Sweeping The fan effect of the rotating cord can be used for quick and easy clearing up. Hold the cord parallel to and above the area to be swept and move the tool to and fro.
When cutting and sweeping you should use full throttle to obtain the best results.

English 29

MAINTENANCE

Carburettor

Your Husqvarna product has been designed and manufactured to specications that reduce harmful emissions. After the engine has used 8-10 tanks of fuel the engine will be run-in. To ensure that it continues to run at peak performance and to minimise harmful exhaust emissions after the running-in period, ask your dealer/ service workshop (who will have a rev counter at their disposal) to adjust your carburettor. The T-screw regulates the throttle setting at idle speed. If the T-screw is turned clockwise this gives a higher idle speed; turning it anti-clockwise gives a lower idle speed.

The L and H-jets are used to adjust the supply of fuel to match the rate that air is admitted, which is controlled with the throttle. If they are screwed clockwise the air/fuel ratio becomes leaner (less fuel) and if they are turned anti-clockwise the ratio becomes richer (more fuel). A lean mixture gives a higher engine speed and a rich mixture gives a lower engine speed.

Low speed jet L

Try to nd the highest idle speed by turning the low speed jet L clockwise then anti-clockwise. When the highest

30 English

speed has been found, turn the low speed jet L 1/4 turn anti-clockwise.
the cutting attachment, nut, support ange and drive disc before adjusting the high speed jet H. Apply full throttle and turn the high speed jet H very slowly clockwise until the engine slows down. Then turn the high speed jet H very slowly anticlockwise until the engine starts to run unevenly. Now turn the high speed jet H slowly clockwise a little way until the engine runs smoothly.
CAUTION! If the cutting attachment rotates when the engine is idling the idle adjustment screw T should be turned anti-clockwise until the cutting attachment stops.
Fine adjustment of the idle speed T
Adjust the idle speed using the idle adjustment screw T, if it is necessary to readjust. First turn the idle adjustment screw T clockwise until the cutting attachment starts to rotate. Then turn the screw anticlockwise until the cutting attachment stops. The idle speed is correctly adjusted when the engine will run smoothly in every position. The idle speed should also be well below the speed at which the cutting attachment starts to rotate.
CAUTION! For optimum adjustment of the carburettor, contact a qualied dealer/service workshop that has a revolution counter at their disposal.
Correctly adjusted carburettor
When the carburettor is correctly adjusted the machine will accelerate without hesitation and burble a little at maximum speed. It is also important that the cutting attachment does not rotate at idle. If the low speed jet L is set too lean it may cause starting difculties and poor acceleration. If the high speed jet H is set too lean it will result in less power, less performance, poor acceleration and/or damage to the engine. If both the L and H jets are set too rich it will results in acceleration problems or too low a working speed.
Adjusting the start throttle speed
The correct start throttle speed is set by means of an adjuster on the rear of the handle next to the cable. Use this screw (4 mm Allen screw) to increase or decrease the start throttle speed.

High speed jet H

The high speed jet H affects the engine power, speed, temperature and fuel consumption. If the high speed jet H is set too lean (screwed in too far) the engine speed will be too high and cause engine damage. Do not let the engine run at full speed for more than 10 seconds.
Note that the engine should not be under load when you adjust the high speed jet H. You should therefore remove
Proceed as follows: 1 Run the machine at idle. 2 Press the start throttle lock as described under the heading Starting and stopping. 3 If the start throttle speed is too low (below 4000 rpm), turn the adjuster screw A clockwise until the cutting attachment starts to rotate. Then turn A clockwise a further 1/2 turn. English 31

Mufer Cooling system

CAUTION! Some mufers are tted with a catalytic converter. See chapter on Technical data to see whether your machine is tted with a catalytic converter. The mufer is designed to reduce the noise level and to direct the exhaust gases away from the operator. The exhaust gases are hot and can contain sparks, which may cause re if directed against dry and combustible material.
To keep the working temperature as low as possible the machine is equipped with a cooling system.
The cooling system consists of: Some mufers are equipped with a special spark arrestor mesh. If your machine has this type of mufer, you should clean the mesh at least once a week. This is best done with a wire brush. Air intake on the starter. Fins on the ywheel. Cooling ns on the cylinder.
Cylinder cover (directs cold air over the cylinder).
Clean the cooling system with a brush once a week, more often in demanding conditions. A dirty or blocked cooling system results in the machine overheating which causes damage to the piston and cylinder.

Bevel gear

On mufers without a catalytic converter the mesh should be cleaned weekly, or replaced if necessary. On mufers tted with a catalytic converter the mesh should be checked, and if necessary cleaned, monthly. If the mesh is damaged it should be replaced. If the mesh is frequently blocked, this can be a sign that the performance of the catalytic converter is impaired. Contact your dealer to inspect the mufer. A blocked mesh will cause the machine to overheat and result in damage to the cylinder and piston. CAUTION! Never use a machine with a defective mufer. The bevel gear is lled with the right quantity of grease at the factory. However, before using the machine you should check that the bevel gear is lled three-quarters full with grease. Use HUSQVARNA special grease.
WARNING! Mufers tted with catalytic converters get very hot during use and remain so for some time after stopping. This also applies at idle speed. Contact can result in burns to the skin. Remember the risk of re!

The grease in the bevel gear does not normally need to be changed except if repairs are carried out.

32 English

Air lter Spark plug
The air lter must be regularly cleaned to remove dust and dirt in order to avoid: Carburettor malfunctions Starting problems Loss of engine power Unnecessary wear to engine parts. Excessive fuel consumption.
The spark plug condition is inuenced by: Incorrect carburettor adjustment. An incorrect fuel mixture (too much or incorrect type of oil). A dirty air lter.
These factors cause deposits on the spark plug electrodes, which may result in operating problems and starting difculties. If the machine is low on power, difcult to start or runs poorly at idle speed: always check the spark plug rst before taking any further action. If the spark plug is dirty, clean it and check that the electrode gap is 0.5 mm. The spark plug should be replaced after about a month in operation or earlier if necessary.
Clean the lter every 25 hours, or more regularly if conditions are exceptionally dusty.

Cleaning the air lter

Remove the air lter cover and take out the lter. Wash it clean in warm, soapy water. Ensure that the lter is dry before retting it. An air lter that has been in use for a long time cannot be cleaned completely. The lter must therefore be replaced with a new one at regular intervals. A damaged air lter must always be replaced. If the machine is used in dusty conditions the air lter should be soaked in oil. See instructions under the heading Oiling the air lter.
CAUTION! Always use the recommended spark plug type! Use of the wrong spark plug can damage the piston/ cylinder. Check that the spark plug is tted with a suppressor.

Oiling the air lter

Always use HUSQVARNA lter oil, art. no. 92-48. The lter oil contains a solvent to make it spread evenly through the lter. You should therefore avoid skin contact. Put the lter in a plastic bag and pour the lter oil over it. Knead the plastic bag to distribute the oil. Squeeze the excess oil out of the lter inside the plastic bag and pour off the excess before tting the lter to the machine. Never use common engine oil. This would drain through the lter quite quickly and collect in the bottom.

English 33
