SAFETY PRECAUTIONS Power chain saws This power chain saw may be used only for sawing wood out of doors. It is intended for the followung uses depending on its class: - Professional and mid-class: Use on small, medium and large trees: felling, limb removal, cutting to length, thinning. - Hobbyklasse: Occasional use on small trees, fruit-tree care, felling, limb removal, cutting to length.
Fuels / Refuelling - - - Stop the engine before refuelling the chain saw. Do not smoke or work near open fires (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. Do not spill fuel or chain oil. When you have spilt fuel or oil immediately clean the chain saw.
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). - Before the saw chain enters the cut, it can slip to the side or jump (caution: high risk of kickback). - This causes the saw to be thrown back toward the user with great force and out of control.
- - 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), first cut the pressure side (A). Then the crosscut can be performed on the tension side (B).
Transport and storage - When changing your location during work switch off the chain saw and actuate the chain brake in order to prevent an inadvertent start of the chain. - Never carry or transport the chain saw with the chain running. - When transporting the chain saw over long distances the guide bar protection cover (delivered with the chain saw) must be applied. - Carry the chain saw with the tubular handle. The guide bar points backwards (20).

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! CAUTION: Do not start the saw until it has been completely assembled and inspected! A Mounting the guide bar and saw chain Use the universal wrench delivered with the chain saw for the following work.
Lift the chain (9) over the sprocket (10). Using your right hand, guide the chain into the top guide groove (11) on the guide bar. Note that the cutting edges along the top of the chain must point in the direction of the arrow! 9 10 E 11 9 12 Pull the chain (9) around the sprocket nose (12) of the guide bar in the direction of the arrow. F First, push the sprocket guard (3) into its fixture (B/4), then push it over the retaining bolts while lifting the saw chain (9) over the chain catch (13).
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.
Fuel CAUTION: This saw is powered by mineral-oil products (gasoline and oil). Be especially careful when handling gasoline . Do not smoke. Keep tool well away from open flames, spark, or fire (explosion hazard). Gasoline 50:1 50:1 Fuel mixture + This tool is powered by a high-performance air-cooled two-stroke engine. It runs on a mixture of gasoline and two-stroke engine oil. The engine is designed for unleaded regular gasoline with a min. octane value of 91 ROZ.
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 flush 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.
Adjusting the chain lubrication The engine must be switched off. You can adjust the oil pump feed rate with the adjusting screw (1). The amount of oil can be adjusted using the universal wrench. Recommended settings: 1 - 25 cm guide bar - 30 cm guide bar - 35 cm guide bar - 40 cm guide bar C To ensure troublefree operation of the oil pump the oil guide groove at the crank case (2) and the oil inlet bore in the guide bar (3) must be cleaned regularly.
Starting the engine Do not start the saw until it has been completely assembled and inspected! Move at least 3m away from the place where you fuelled the saw. Make sure you have a good footing, and place the saw on the ground in such a way that the chain is not touching anything. Engage the chain brake (lock). Grasp the rear handle firmly in one hand and hold the saw firmly against the ground. Press with one knee on the rear handle. A IMPORTANT: The choke switch (5) is coupled to the throttle lever (1).
Checking the chain brake Do not work with the chain saw without first checking the chain brake! Start the engine as described (make sure you have a good footing, and place the chain saw on the ground in such a way that the guide bar is free of contact). Grasp the tubular handle firmly with one hand and hold the grip with the other. 7 With the engine running at moderate speed, press the hand guard (7) in the direction of the arrow with the back of your hand until the chain brake engages.
Adjusting the carburetor (only for not EU-countries) 9 Carburetor adjustment is necessary for optimum engine performance, for safer and more economical operation. The engine should be warm, the air filter clean, and the chain properly tensioned. Have carburetor adjustment done by an authorised MAKITA service centre. 8 The carburetor is factory-adjusted for the air pressure at sea level.
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 flour. 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.
All cutters must be sharpened to the same angle, 30°. Different angles result in a roughly, irregularly running chain, increase wear and tear and cause chain beakage. The 85° front rake of the cutter results from the cut depth of the round file. If the proper file is used in the right manner, the correct front rake will be obtained automatically. C Files and how to work with them Use a special round file for chains (dia. 4 mm) for sharpening the chain. Normal round files are not appropriate for this work.
Cleaning the sprocket interior, checking and replacing the chain catch sleeve 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: Do not start the saw until it has been completely assembled and inspected! 1 2 3 Remove the sprocket guard (4) (see section on „PUTTING INTO OPERATION“ A – B) and clean the interior with a brush.
Replacing the saw chain 7 CAUTION: Use only chains and guide bars designed for this saw (see the Extract from the spare-parts list)! Check the sprocket (7) before mounting a new chain. Remove the sprocket guard (see ”PUTTING INTO OPERATION” A-H) CAUTION: Worn out sprockets (8) may damage the new chain and must therefore be replaced. Replacing the clutch drum and sprocket Release the chain brake if necessary. Lever off the circlip (11) using the universal wrench and remove the washer (10).
Replacing the spark plug CAUTION: Do not touch the spark plug or plug cap if the engine is running (high voltage). Switch off the engine before starting any maintenance work. A hot engine can cause burns. Wear protective gloves! 0,5 mm The spark plug must be replaced in case of damage to the insulator, electrode erosion (burn) or if the electrodes are very dirty or oily. Pull the plug cap (1) off the spark plug. Use only the combination wrench supplied with the saw to remove the spark plug.
Replacing the return spring unit 9 Remove and reinstall the fan housing and cable drum (see ”Replacing the starter cable”). Carefully remove the return spring unit (9) from the fan housing. CAUTION: Danger of injury! If the spring is broken it can jump out! Carefully fit the new return spring unit. C Cleaning the muffler CAUTION: If the engine is hot there is a risk of burning. Wear protective gloves. Remove the sprocket guard (see ”PUTTING INTO OPERATION” Fig. B).
