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 English 9

Stop switch

Use the stop switch to switch off the engine. 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.

Quick release

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. 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 clearing saw. Certain harnesses also have a quick release tted to the support hook.
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.

Vibration damping system

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 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.

Saw blades are intended for cutting brous types of wood.
The lock screw must be tightened securely for ballbearing-mounted support cups.
Grass blades and grass cutters are intended for cutting coarse grass.

Cutting equipment

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. General rules A trimmer head is intended for trimming grass. Shredder blades are intended for cutting coarse grass and bushes.
Only use cutting attachments with the guards we recommend! See the chapter on Technical data.

incorrectly set saw blade increases the risk of jamming and blade thrust, and damage to the saw blade.

Sharpening the saw blade

See the cutting attachment packaging for correct sharpening instructions.
Check the cutting attachment for damage or cracks. A damaged cutting attachment should always be replaced.
A correctly sharpened blade is essential for working efciently and to avoid unnecessary wear to the blade and clearing saw.
Sharpening grass cutters and grass blades
See the cutting attachment packaging for correct sharpening instructions. Sharpen blades and cutters using a single-cut at le. Sharpen all edges equally to maintain the balance of the blade.
Make sure that the blade is well supported when you le it. Use a 5.5 mm round le with a le holder.
WARNING! Always discard a blade that is bent, twisted, cracked, broken or damaged in any other way. Never attempt to straighten a twisted blade so that it can be reused. Only use original blades of the specied type.
The ling angle is 15. File alternate teeth to the right and those in between to the left. If the blade has been heavily pitted by stones it may be necessary to dress the top edges of the teeth with a at le, in exceptional cases. If so, this should be done before ling with a round le. The top edges must be led down by the same amount for all the teeth.
Adjust the blade setting. This should be 1 mm.

English 13

Trimmer head
IMPORTANT! Always ensure the trimmer cord is wound tightly and evenly around the drum, otherwise the machine will generate harmful vibration. Only use the recommended trimmer heads and trimmer cords. These have been tested by the manufacturer to suit a particular engine size. This is especially important when a fully automatic trimmer head is used. Only use the recommended cutting attachment. See the chapter on Technical data.
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 23

Warm engine
Use the same starting procedure as for a cold engine but without setting the choke control in the choke position. Start throttle: (FC2255, FC2255W, BC2255, MC2255) Set the throttle to the start position by moving the choke control to the choke position and then returning it to its original position. Start throttle: (BC2255, MC2255) Set the throttle to the start position by rst pressing the throttle lockout and the throttle trigger, then pressing the start throttle button (A). Then release the throttle lockout and the throttle trigger, followed by the start throttle button. The throttle function is now activated. To return the engine to idle, press the throttle lockout and throttle trigger again.

Stopping

Stop the engine by switching off the ignition. BC2255, MC2255

Heated handles Starting

FC2255W 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. Models equipped with heating elements in the handles have an on/off switch on the throttle handle to control the heat. Both the left and right handles have heating elements that automatically maintain a temperature of roughly 70 when the heat is turned on.
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. Never twist the starter cord around your hand. Repeat pulling the cord until the engine starts. When the engine starts. return choke control to run position and apply full throttle; the throttle will automatically disengage from the start setting. CAUTION! Do not pull the starter cord all the way out and do not let go of the starter handle when the cord is fully extended. This can damage the machine.

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.

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: 1 Always work at full throttle. 2 Avoid 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.
Shredding dense vegetation with a shredder blade
The brush cutter is used to shred vegetation, i.e. by woking it up and down through dense grass and brush.
The shredder blade must not be used on vegetation with a stem diameter larger than 2 cm.

English 29

MAINTENANCE

Air lter

The air lter must be regularly cleaned to remove dust and dirt in order to avoid: CAUTION! Never use a machine with a defective mufer. Carburettor malfunctions Starting problems Loss of engine power Unnecessary wear to engine parts. Excessive fuel consumption.
Clean the lter every 25 hours, or more regularly if conditions are exceptionally dusty.

English 31

Cleaning the air lter
Remove the air lter cover and take out the lter. Blow clean with compressed air. 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.

Bevel gear

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.

Winter use

The bevel gear is lled with the right amount of grease at the factory. However, before using the machine you should check that the bevel gear is lled 3/4 full with grease. Use JONSERED special grease. The grease in the bevel gear does not normally need to be changed except if repairs are carried out. Running problems can occur when using the machine in the cold and snowy conditions caused by: Too low engine temperature. Icing of the air lter and carburettor. Partly mask the air inlet on the starter to increase the working temperature of the engine. Preheat the intake air to the carburettor by utilising the heat from the engine.
Special measures are therefore often required:
There is a special winter kit available when using the machine in cold and/or snowy conditions, this includes the following:

Drive shaft

The drive shaft must be greased every three months during full-time use. Contact your dealer if you are uncertain about the procedure.

a special air lter cover without air intake (A) a cover for the lter holder (B) a cover for the starter housing (C) a special wear guard with an air duct (D) that routes the hot air from the mufer to the carburettor a special air lter with a coarser mesh size (E)

Spark plug

The spark plug condition is inuenced by: Incorrect carburettor adjustment. An incorrect fuel mixture (too much or incorrect type of oil).

32 English

Temperature 0C or colder:
Fit the covers for the starter housing and air lter holder using the three screws provided as shown in the gure.
Temperature -5C or colder:
Dismantle the machines wear guard, and t the wear guard from the winter kit as shown in the gure. Pay particular attention that the opening on the air duct is positioned in the centre of the hole in the air lter holder.
Remove the air lter and air lter cover from the machine. Fit the air lter and air lter cover supplied with the winter kit.
IMPORTANT! If the temperature rises above -5C or 0C respectively the machine MUST be restored to its normal set-up. Otherwise there is a risk of overheating, which can cause severe engine damage. IMPORTANT! Any maintenance other than that described in this manual must be carried out by your servicing dealer (retailer).
