Protective equipment In order to avoid head, eye, hand or foot injuries as well as to protect your hearing the following protective equipment must be used during operation of the chain saw: The kind of clothing should be appropriate, i. e. it should be tight-tting but not be a hindrance. Do not wear jewellery or clothing which could become entangled with bushes or shrubs. If you have long hair, always wear a hairnet! It is necessary to wear a protective helmet whenever working with the chain saw. The protective helmet (1) is to be checked in regular intervals for damage and is to be replaced after 5 years at the latest. Use only approved protective helmets. The face shield (2) of the protective helmet (or the goggles) protects against sawdust and wood chips. During operation of the chain saw always wear a goggle or a face shield to prevent eye injuries. Wear adequate noise protection equipment (ear muffs (3), ear plugs, etc.). Octave brand analysis upon request. The safety jacket (4) is provided with special signal-coloured shoulder straps and is comfortable and easy to care for. The protective brace and bib overall (5) is made of a nylon fabric with 22 layers and protects against cuts. We strongly recommend its use.
Fuels / Refuelling - Stop the engine before refuelling the chain saw. - Do not smoke or work near open res (5). - Let the engine cool down before refuelling. - Fuels can contain substances similar to solvents. Eyes and skin should not come in contact with mineral oil products. Always wear protective gloves when refuelling. Frequently clean and change protective clothes. Do not breathe in fuel vapors. Inhalation of fuel vapours can be hazardous to your health. - Do not spill fuel or chain oil. When you have spilt fuel or oil immediately clean the chain saw. Fuel should not come in contact with clothes. If your clothes have come in contact with fuel, change them ot once. - Ensure that no fuel or chain oil oozes into the soil (environmental protection). Use an appropriate base. - Refuelling is not allowed in closed rooms. Fuel vapors will accumulate near the oor (explosion hazard). - Ensure to rmly tighten the screw plugs of the fuel and oil tanks. - Change the place before starting the engine (at least 3 m from the place of refuelling) (6). - Fuel cannot be stored for an unlimited period of time. Buy only as much as will be consumed in the near future. - Use only approved and marked containers for the transport and storage of fuel and chain oil. Ensure children have no access to fuel or chain oil. Putting into operation - Do not work on your own. Another person must be nearby in case of emergencies (within shouting distance). - Ensure that there are no children or other people within the working area. Pay attention to any animals in the working area, as well (7). - Before starting work the chain saw must be checked for perfect function and operating safety according to the prescriptions. Check especially the function of the chain brake, the correct mounting of the guide bar, the correct sharpening and tightening of the chain, the rm mounting of the sprocket guard, the easy motion of the throttle lever and the function of the throttle lever lock, the cleanliness and dryness of the handles, and the function of the ON/OFF switch. - Put the chain saw only into operation if it is completely assembled. Never use the chain saw when it is not completely assembled. - Before starting the chain saw ensure that you have a safe footing. - Put the chain saw into operation only as described in this instruction manual (8). Other starting methods are not allowed. - When starting the chain saw it must be well supported and securely held. The guide bar and chain must not be in contact with any object. - When working with the chain saw always hold it with both hands. Take the back handle with the right hand and the tubular handle with the left hand. Hold the handles tightly with your thumbs facing your ngers. - CAUTION: When releasing the throttle lever the chain will keep on running for a short period of time (free-wheeling). - Continuously ensure that you have a safe footing. - Hold the chain saw such that you will not breathe in the exhaust gas. Do not work in closed rooms (danger of poisoning). - Switch off the chain saw immediately if you observe any changes in its operating behavior. - The engine must be switched off before checking the chain tension, tightening the chain, replacing it or clearing malfunctions (9). - When the sawing device is hit by stones, nails or other hard objects, switch off the engine immediately and check the sawing device. - When stopping work or leaving the working place switch off the chain saw (9) and put it down such that nobody is endangered. - Do not put the overheated power chain saw in dry grass or on any inammable objects. The mufer is very hot (danger of re). - CAUTION: Oil dropping from the chain or guide bar after having stopped the saw chain will pollute the soil. Always use an appropriate base.

Kickback - When working with the chain saw dangerous kickbacks may occur. - Kickback occurs when the upper part of the end of the guide bar inadvertently touches wood or other hard objects (10). - This causes the saw to be thrown back toward the user with great force and out of control. Risk of injury! In order to prevent kickback, follow these rules: Only specially-trained persons should perform plunge cuts, i.e., piercing timber or wood with the tip of the saw! Never apply the end of the bar when starting to make a cut. Always observe the end of the guide bar. Be careful when continuing an already started cut. When starting to cut the chain must be running. Ensure that the chain is always sharpened correctly. Pay special attention to the height of the depth limiter. Never cut several branches at the same time. When cutting a branch ensure that no other branch is touched. When crosscutting a trunk be aware of the trunks next to it.
Working behavior/Method of working - Only use the chain saw during good light and visibility periods. Be aware of slippery or wet areas, and of ice and snow (risk of slipping). The risk of slipping is extremely high when working on recently peeled wood (bark). - Never work on unstable surfaces. Make sure that there are no obstacles in the working area, risk of stumbling. Always ensure that you have a safe footing. - Never saw above your shoulder height (11). - Never saw while standing on a ladder (11). - Never climb up into trees to perform sawing with the chain saw. - Do not work leaning too far over. - Guide the chain saw in such a way that no part of your body is within the elongated swivelling range of the saw (12). Use the chain saw for sawing wood only. Avoid touching the ground with the chain saw while it is still running. Never use the chain saw for lifting up or removing pieces of wood or other objects. Remove foreign objects such as sand, stones and nails found within the working area. Foreign objects may damage the sawing device and can cause dangerous kickback. When sawing precut timber use a safe support (sawing jack, 13). Do not steady the workpiece with your foot, and do not allow anyone else to hold or steady it. Secure round pieces against rotation. For cutting down trees or performing crosscuts the spike bar (13, Z) must be applied to the wood to be cut. Before performing a crosscut rmly apply the spike bar to the timber, only then can the timber be cut with the chain running. For this the chain saw is lifted at the back handle and guided with the tubular handle. The spike bar serves as a centre of rotation. Continue by slightly pressing down the tubular handle and simultaneously pulling back the chain saw. Apply the spike bar a little bit deeper and once again lift the back handle. When the timber must be pierced for cutting or longitudinal cuts are to be performed it is urgently recommended to have this carried out by specially trained persons only (high risk of kickback). Do longitudinal - lengthwise - cuts at the lowest possible angle (14). Be very careful when doing this type of cut, as the spike bar cannot grip. The saw must be running whenever you remove the chain saw from the wood. When performing several cuts the throttle lever must be released in between.

Be careful when cutting splintery wood. Cut pieces of wood may be pulled along (risk of injuries). When cutting with the upper edge of the guide bar, the chain saw may be pushed in the direction of the user if the chain gets clamped. For this reason use the lower edge of the bar whenever possible. The chain saw will then be pushed away from you (15). If the timber is under tension (16), rst cut the pressure side (A). Then the crosscut can be performed on the tension side (B). Thus clamping of the guide bar can be avoided. CAUTION: People felling trees or cutting of branches must be specially trained. High risk of injuries! 15
When cutting of branches, the chain saw should be supported on the trunk. Do not use the end of the bar for cutting (risk of kickback). Be aware of branches under tension. Do not cut free branches from below. Never perform detensioning cuts while standing on the trunk.
Before cutting down a tree ensure that a) only those people are within the working area which are actually involved in cutting down the tree. b) every worker involved can withdraw without stumbling (the people should withdraw backwards in a diagonal line, i. e. at a degree of 45). c) the bottom part of the trunk is free from foreign objects, underbrush and branches. Make sure to have a safe footing (risk of stumbling). d) the next working place is at least 2 1/2 tree lengths away (17). Before cutting down the tree check the direction of fall and make sure that there are neither people nor objects within a distance of 2 1/2 tree lengths. - Judging the tree: Direction of hanging - loose or dry branches - height of the tree - natural overhang - is the tree rotten? - Take into account the direction and speed of the wind. If strong gusts are occurring, do not do any felling. - Cutting the roots: Start with the strongest root. First do the vertical and then the horizontal cut. - Notching the trunk (18, A): The notch determines the direction of fall and guides the tree. The trunk is notched perpendicular to the direction of fall and penetrates 1/3 -1/5 of the trunk diameter. Perform the cut near the ground. - When correcting the cut, always do so over the whole width of the notch. - Cut down the tree (19, B) above the bottom edge of the notch (D). The cut must be exactly horizontal. The distance between both cuts must be approx. 1/10 of the trunk diameter. - The material between both cuts (C) serves as a hinge. Never cut it through, otherwise the tree will fall without any control. Insert felling wedges in time. - Secure the cut only with wedges made of plastic or aluminium. Do not use iron wedges. If the saw hits an iron wedge the chain can be seriously damaged or torn. - When cutting down a tree always stay sidewards of the falling tree. - When withdrawing after having performed the cut, be alert for falling branches. - When working on sloping ground the user of the chain saw must stay above or sidewards of the trunk to be cut or the tree already cut down. - Be alert for trunks which may roll towards you.

PUTTING INTO OPERATION

CAUTION:
Before doing any work on the guide bar or chain, always switch off the engine and pull the plug cap off the spark plug (see Replacing the spark plug). Always wear protective gloves!
Start the chain saw only after having assembled it completely and inspected.
Mounting the guide bar and saw chain
Use the universal wrench delivered with the chain saw for the following work.
Put the chain saw on a stable surface and carry out the following steps for mounting the guide bar and saw chain: Release the chain brake by pulling the hand guard (1) in direction of arrow. Unscrew retaining nuts (2). Pull off the sprocket guard (3).
Remove the plastic transport cover (*) and dispose of properly. Turn chain tensioning screw (4) to the left (counter-clockwise) until the pin (5) of the chain tensioner is underneath the threaded pin (6).

Put on the guide bar (7). Make sure that the pin (5) of the chain tensioner engages in the hole in the guide bar.
Lift the chain (9) over the sprocket (8). CAUTION: Do not insert the chain between the chain sprocket and the disc. Guide the chain from above about halfway into the groove (10) on the guide bar. Place the chain over the chain catch (11) on the bottom. CAUTION: Note that the cutting edges along the top of the chain must point in the direction of the arrow!
Pull the chain (9) around the sprocket nose (12) of the guide bar in the direction of the arrow.
Replace the sprocket guard (3). Tighten the nuts (2) only hand-tight to begin with.

Tightening the saw chain

Turn the chain tensioning screw (4) to the right (clockwise) until the saw chain catches in the groove on the lower side of the guide bar (see circle). Slightly lift the end of the guide bar and turn the chain adjusting screw (4) to the right (clockwise) until the chain rests against the bottom side of the guide bar. While still holding up the tip of the guide bar, tighten the retaining nuts (2) with the universal wrench.
Checking the chain tension
The tension of the chain is correct if the chain rests against the bottom side of the guide bar and can still be easily turned by hand. While doing so the chain brake must be released. Check the chain tension frequently - new chains tend to get longer during use! When checking the chain tension the engine must be switched off. NOTE: It is recommended to use 2-3 chains alternatively. In order to guarantee uniform wear of the guide bar the bar should be turned over whenever replacing the chain.
Retightening the saw chain
Loosen the nuts (2) about one turn with the universal wrench. Raise the tip of the guide bar a little and turn the chain tensioning screw (4) to the right (clockwise) until the saw chain is again up against the bottom edge of the guide bar (see circle). While keeping the tip of the guide bar raised, tighten the nuts (2) again with the universal wrench.

Chain brake

The DCS460, 461, 500, 501 comes with an inertia chain brake as standard equipment. If kickback occurs due to contact of the guide-bar tip with wood (see SAFETY PRECAUTIONS, page 6), the chain brake will stop the chain through inertia if the kickback is sufciently strong. The chain will stop within a fraction of a second. The chain brake is installed to block the saw chain before starting it and to stop it immediately in case of an emergency. IMPORTANT: NEVER run the saw with the chain brake activated (except for testing, see Testing chain brake)! Doing so can very quickly cause extensive engine damage!

The Storage of Fuel

Fuels have a limited storage life. Fuel and fuel mixtures age through evaporation, especially at high temperatures. Aged fuel and fuel mixtures can cause starting problems and damage the engine.Purchase only that amount of fuel, which will be consumed over the next few months. At high temperatures, once fuel has been mixed it should be used up in 6-8 weeks. Store fuel only in proper containers, in dry, cool, secure locations!
In case MAKITA high-performance two-stroke engine oil is not available, it is urgently recommended to use a mixture ratio of 50:1 with other two-stroke engine oils, as otherwise optimum operation of the engine cannot be guaranteed. Caution: Do not use ready-mixed fuel from petrol stations. The correct mixture ratio: 50:1 50:1 when using MAKITA high-performance two-stroke engine oil, i. e. mix 50 parts gasoline with 1 part oil. when using other synthetic two-stroke engine oils (quality grade JASO FC or ISO EGD), i. e. mix 50 parts gasoline with 1 part oil.
AVOID SKIN AND EYE CONTACT
Mineral oil products degrease your skin. If your skin comes in contact with these substances repeatedly and for an extended period of time, it will desiccate. Various skin deseases may result. In addition, allergic reactions are known to occur. Eyes can be irritated by contact with oil. If oil comes into your eyes, immediately wash them with clear water. If your eyes are still irritated, see a doctor immediately!
NOTE: For preparing the fuel-oil mixture rst mix the entire oil quantity with half of the fuel required, then add the remaining fuel.

Chain oil

Use an oil with adhesive additive for lubricating the chain and guide bar. The adhesive additive prevents the oil from being ung off the chain too quickly. We recommend the use of chain oil which is bio-degradable in order to protect the environment. The use of bio-degradable oil may even be required by local regulations. The chain oil BIOTOP sold by MAKITA is made of special vegetable oils and is 100% bio-degradable. BIOTOP has been granted the blue angel (Blauer Umweltschutz-Engel) for being particularly environment-friendly (RAL UZ 48). BIOTOP chain oil is available in the following sizes: 1l 5l order number 610 order number 611
Bio-degradable oil is stable only for a limited period of time. It should be used within 2 years from the date of manufacture (printed on the container).
Important note on bio-degradable chain oils
If you are not planning to use the saw again for an extended period of time, empty the oil tank and put in a small amount of regular engine oil (SAE 30), and then run the saw for a time. This is necessary to ush out all remaining bio-degradable oil from the oil tank, oil-feed system, chain and guide bar, as many such oils tend to leave sticky residues over time, which can cause damage to the oil pump or other parts. The next time you use the saw, ll the tank with BIOTOP chain oil again. In case of damage caused by using waste oil or unappropriate chain oil the product guarantee will be null and void. Your salesman will inform you about the use of chain oil.

Checking adjusting screw (H) Before starting the engine make sure that adjusting screw (H) is turned out counterclockwise until it reaches a noticeable stop. The limitations do not prevent excessively lean running! 1. 2. 3. 4. 5. Start engine and let it warm up (3-5 minutes) Set idle Check acceleration Set maximum permissible speed Check idle speed
5. Check idle speed Check the idle speed after setting the top speed (the cutting tool must not rotate!). Repeat the adjustment procedure starting at Step 2, until the engine runs with the correct idle speed, good acceleration, and maximum permissible speed.
2. Set idle Set the idle speed per the technical specications. Turning the adjusting screw (S) in (clockwise) increases the idle speed. Turning it out (counter-clockwise) lowers the idle speed. The cutting tool must not rotate!
3. Check acceleration When the throttle is pressed, the engine should go smoothly from idle to high speed. Turn adjusting screw (L) out (counterclockwise) in small increments until acceleration is good.
Adjusting the carburetor (only for not EU-countries)
Carburetor adjustment is necessary for optimum engine performance, for safer and more economical operation. The engine should be warm, the air lter clean, and the chain properly tensioned. Have carburetor adjustment done by an authorised MAKITA service centre. The carburetor is factory-adjusted for the air pressure at sea level. At other elevations or under other conditions of weather, temperature, or humidity, or when breaking in a new engine, it may be necessary to make slight adjustments to the carburetor. You will need a tachometer (9, part No. 210) for optimum adjustment. Do not go below the specied setting of the main nozzle (H). Doing so may cause engine damage due to overheating and insufcient lubrication! Use the supplied carburetor screwdriver (8) for carburetor adjustment. It has a moulded-on projection that aids in adjusting. Before undertaking the adjustment, run the engine for 3-5 minutes to warm it up, but not at high speed!
3. Check acceleration When the throttle is pressed, the engine should go smoothly from idle to high speed. If this is too slow, turn the adjusting screw (L) in small (max. 1/8 turns) increments counter-clockwise. 4. Check top speed The basic setting H=11/2 and L=11/2 gives a maximum speed of about 13,800 rpm. For higher speed (electronically limited ), turn the adjusting screw (H) a maximum 1/4 turn clockwise.The top speed in the governor can be clearly heard from the ignition misses. Note: Since there is an electronic speed governor (limiter) at 13,800 rpm that cuts off the ignition current, the top speed cannot be read from the tachometer. Important: To prevent engine damage, never go below setting (H) 11/4 turns. 5. Check idle speed

Check the idle speed after setting the top speed (the chain must not move). Repeat the adjustment procedure starting at Step 2, until the engine runs with the correct idle speed, good acceleration, and top speed.
For proper adjustment, proceed as follows: 1. Basic setting (engine off) Start engine and warm up. 2. Set idle 3. Check acceleration 4. Check top speed 5. Check idle speed Repeat steps 2-5 until you get the right idle speed, good acceleration and maximum permissible 1. Basic setting Carefully turn the adjusting screws for the main nozzle (H) and idle nozzle (L) clockwise until you feel a stop. Turn adjusting screws (H) 11/2 and (L) 11/2 counter-clockwise. 2. Set idle Set the idle speed per the technical specications. Turning the adjusting screw (S) in (clockwise) increases the idle speed. Turning it out (counter-clockwise) lowers the idle speed. In no case should the chain move.

MAINTENANCE

Sharpening the saw chain
CAUTION: Before doing any work on the guide bar or chain, always switch off the engine and pull the plug cap off the spark plug (see Replacing the spark plug). Always wear protective gloves! The chain needs sharpening when: The sawdust produced when sawing damp wood looks like wood our. The chain penetrates the wood only under great pressure. The cutting edge is visibly damaged. The saw is pulled to the left or right when sawing. This is caused by uneven sharpening of the chain. Important: Sharpen frequently, but without removing too much metal! Generally, 2 or 3 strokes of the le will be enough. Have the chain resharpened at a service centre when you have already sharpened it yourself several times.
Proper sharpening: CAUTION: Use only chains and guide bars designed for this saw (see the Extract from the spare-parts list)! All cutters must be of the same length (dimension a). Cutters with different lengths result in rough running of the chain and can cause cracks in the chain. The minimum cutter length: 3 mm. Do not resharpen the chain when the minimum cutter length has been reached; at this point, the chain must be replaced (see the Extract from the spare-parts list and Replacing the saw chain). The depth of the cut is determined by the difference in height between the depth limiter (round nose) and the cutting edge. The best results are obtained with a depth-limiter depth of 0.64 mm (.025). CAUTION: Excessive depth increases the risk of kickback!

0,64 mm (.025)

3 mm (0.11)
The sharpening angle () must be identical for all cutters! 25 for chain type 686, for chain type 086, for chain type 093 The teeth will have the proper angle () automatically if the proper round le is used. 60 for chain type 686, for chain type 086, 093, 484 Different angles result in a roughly, irregularly running chain, increase wear and tear and cause chain beakage.
Files and how to work with them
Use a special saw chain round le for sharpening. Standard round les are unsuitable. For the order number, see Accessories. Type 086, 484, 686: File the rst cutter half with a 4,8 mm dia. round saw-chain le, then switch to a 4.5 mm dia. le. Type 093, 099: File the rst cutter half with a 5,5 mm dia. round saw-chain le, then switch to a 4.8 mm dia. le. The le should cut only when pushed forwards (arrow). Lift the le when leading it backwards. First sharpen the shortest cutter. The length of this cutter is then the standerd for all other cutters of the chain.

Chain typ 093

Chain typ 086, 484, 686, 099
New saw teeth must be led to the exact same shape as the used teeth, including on their running surfaces. File depending on chain type (90 or 10 to the guide bar).
A le holder makes le guidance easier. It is marked for the correct sharpening angle of: = 25 = 30 = 35 (keep the marks parallel with the chain when ling, see illustration) and limits the cut depth to the correct 4/5 of the le diameter. See Accessories for the order number.
After having sharpened the chain, the height of the depth limiter must be checked by means of a chain gauge. See Accessories for the order number. Correct even the smallest excess height with a special at le (1). See Accessories for the order number. Round off the front of the depth limiter (2).
Cleaning the brake band and sprocket interior
CAUTION: Before doing any work on the guide bar or chain, always switch off the engine and pull the plug cap off the spark plug (see Replacing the spark plug). Always wear protective gloves! CAUTION: Start the chain saw only after having assembled it completely and inspected. Remove the sprocket guard (1) (See PUTTING INTO OPERATION gs. B) and clean the interior with a brush. Turn the chain tensioning screw (2) to the left (counter-clockwise) until pin (3) of the chain tensioner is underneath the threaded pin (4). Remove the chain (5) and guide bar (6).
NOTE: Make sure there are no residues or foreign matter remaining in the oil guide groove (7) or on the chain tensioner (3). For replacing the guide bar, chain, and sprocket see PUTTING INTO OPERATION.

NOTE: The chain brake is a very important safety device and like any other component subject to normal wear and tear. Regular inspection and maintenance are important for your own safety and must be done by a MAKITA service centre.

Cleaning the guide bar

CAUTION: Protective gloves must be worn. Regularly inspect the bearing surfaces of the guide bar for damage, and clean them with a suitable tool.

Replacing the saw chain

CAUTION: Use only chains and guide bars designed for this saw (see the Extract from the spare-parts list)! When changing chain types, always make sure to use the clutch drum cpl. (12). It may be necessary to change the clutch drum cpl. IMPORTANT: If the chain type is changed from.325 to 3/8, the chip deector must be modied. See under Instructions for changing the chain type.
Check the sprocket before mounting a new chain. Worn out sprockets (8) may damage the new chain and must therefore be replaced. Remove the sprocket guard (See PUTTING INTO OPERATION gs. B).
Remove the chain and guide bar. Remove circlip (9). CAUTION: The circlip will pop out of the groove. When removing it, hold your thumb against it to prevent it from popping off. Remove thrust washer (11). If the chain sprocket (8) is worn, the clutch drum cpl. (12) must be replaced. For the part number consult the Extract from the spare parts list. Put on the washer disc (13), new clutch drum cpl. (12), cup washer (11) and new circlip (9) montieren (for the order number see Extract from the spare parts list). For replacing the guide bar, chain, and sprocket see PUTTING INTO OPERATION A-H.
NOTE: Dont use a new chain on a worn chain sprocket. By the time 2 chains have worn, the sprocket has become worn out, so it should be replaced at least at every second chain replacement. To distribute the chain oil evenly, run a new chain at half-throttle for a few minutes before use. New chains stretch, so check the chain tension frequently (see Checking the chain tension).
Instructions for changing the chain type
Always wear protective gloves! Before using a 3/8 saw chain, be sure to rst cut out the marked section of the chip deector (14)! To do this, rst cut along the marking (15) with a sharp knife and then cut across to remove the piece.
NOTE: If switching to chain type.325 it will be necessary to install a newchip deector (see Extract from the spare parts list for the part number).

Cleaning the air lter

CAUTION: To prevent eye injury, always wear eye protection when cleaning the lter with compressed air! Do not use fuel to clean the air lter. Disengage the cover clasp (1) with the universal wrench and take off the cover (2). Push up the combination switch (3) (Choke position) to prevent dirt particles from falling into the carburetor. Unhook the clasp (4) in the direction of the arrow with a nger or the universal wrench. Pull the air lter (5) up and out. Take the pre-lter (5a) out of the cover (2). IMPORTANT: Cover the intake opening with a clean cloth to prevent dirt particles from getting into the carburetor. Choosing the right lter: The eece lter is for use in dry or dusty conditions. The nylon lter (available as accessory) is for use in damp conditions. The pre-lter keeps out sawdust, and prevents powder snow from getting in when working in winter. Pry apart the top and bottom of the air lter as shown in Figure. Cleaning the eece lter: Carefully tap out dust or carefully blow out dust from the inside with compressed air. Do not brush the eece, as this will force dirt particles into the fabric. If the lter is very dirty, it can be washed in lukewarm water with regular dishwashing detergent. Note that the eece lter does not need to be cleaned until there is a noticeable loss of power. If cleaning the lter does not bring an improvement in performance, it is time to replace it. Cleaning the nylon lter: Use a soft brush or blow out dirt from the inside with compressed air. If the lter is very dirty, it can be washed in lukewarm water with regular dishwashing detergent. Clean frequently (several times a day) when working in very dusty or dirty conditions. Full engine power is possible only with a clean air lter! Cleaning the pre-lter: When the pre-lter becomes dirty, wash it in lukewarm soapy water using standard dishwashing liquid. Let the air lter dry completely. Put the top and bottom sections back together. Place the pre-lter back in the cover. Before assembling the air lter, check the choke ap for any dirt particles. If there are any, remove them with a brush. CAUTION: If the air lter becomes damaged, replace immediately! Pieces of cloth or large dirt particles can destroy the engine! Insert the air lter (5) and press the clasp (4) in the direction of the arrow until it engages. Move the combination switch (3) down and press the throttle (6) once all the way, to deactivate the half-throttle lock. Put the cover (2) back on and afx it with the cover clasps (1).

Replacing the return spring pack
Disassemble the fan housing and cable drum (see above). CAREFUL! Injury hazard! The return spring can pop out! Always wear eye protection and protective gloves! Lightly tap the fan housing on a wooden surface with the entire surface of the hollow side, and hold it down. Now lift the fan housing carefully and in small steps. This will allow the return spring pack (13), which should now have fallen out, to relax in a controlled manner if the return spring has popped out of the plastic pack. Carefully insert a new return spring cassette and press down until it engages. Place the cable drum on it and turn it slightly until the return spring engages. Install the spring (6) and driver (8) and screw on tight with screw (7). Tension the spring (see above).

Mounting the fan housing

Insert the air guide (3) in the fan housing so that the three recesses (4) engage. Position the fan housing against the housing, press against it lightly and pull the starter grip until the starter engages. Tighten screws (1).
Replacing the starter spring

Cleaning the cylinder area
Remove cover. Remove the fan housing. CAUTION: To prevent eye injury, always wear eye protection when cleaning the lter with compressed air! The entire area (14) can now be brushed clean or cleaned with compressed air. A bottle brush can come in handy for cleaning out the cylinder ribs.
