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). Hold the tubular handle tightly with one hand and press the chain saw to the ground. Steady the rear handle by standing in the hand guard. B STOP Cold start: Prime the fuel pump (5) by pressing it several times until you can see fuel in the pump. Move the combination switch (1) up (choke position). Grasp handle (hand pressure actuates the grip throttle lever lock (4)). Push the throttle (3) in all the way and hold it. Press the throttle lock (2) and release the throttle (3) (the throttle lock will hold the throttle at half-throttle position). Slowly pull out the starter cable (6) until you notice resistance (the piston is positioned before the top dead center). Now pull the starter cable with a fast and forceful move-ment until you hear the first ignition. CAUTION: Do not pull out the starter cable more than approx. 20"(50 cm), and lead it back by hand. When you hear the first ignition, put the combination switch (1) in position "I" and pull the starter cable again. As soon as the engine is running, press the throttle (3) to release the half-throttle lock (2), allowing the engine to idle. CAUTION: As soon as the engine is started it must be put in idle to prevent the chain brake from being damaged. Now release the chain brake. Warm start: As described above for cold starting, but without using the choke position. Stopping the engine Push the combination switch (1) down to position . Checking the safety chain brake Do not work with the saw without first checking the chain brake! Start the engine as described (make sure you have a good footing, and place the saw on the ground in such a way that the blade is free of contact). Grasp the tubular handle firmly with one hand and hold the rear handle with the other. 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. The chain should stop immediately. Immediately release the throttle and release the chain brake. IMPORTANT: If the chain does not stop immediately when you test the chain brake, do NOT use the saw! Take the saw to a MAKITA service center for repair. 7 Adjusting the carburetor (only an authorized service center) CAUTION: Optimum perfornance can only be achieved if the carburetor is adjusted correctly. For this work, which should be carried out only by an expert, the engine must be warmed up and the air filter must be clean. The carburetor has been adjusted by MAKITA on the basis of atmosheric pressure conditions at sea level. Other atmospher-SERVICE ic pressure conditions or the running-in process of a new engine may require readjustment of the carburetor. D E Set idle speed Adjust the idle speed using a screwdriver (8), blade width 0.16" (4 mm). If the chain turns when the engine is idling, unscrew the throttle-valve stop screw (9) until the chain stops. If the engine runs unevenly, screw the screw (9) in. 9 8 MAINTENANCE Sharpening the saw chain STOP 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. 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 file will be enough. Have the chain resharpened at a service center when you have already sharpened it yourself several times. A 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. Minimum cutter length is 0.11" (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 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 the depth-limiter depth of .025" (0.65 mm). CAUTION: Excessive depth increases the risk of kickback!B min. 3 mm (0.11”) .025" (0.65 mm) .025" (0.65 mm) 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 breakage. 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 automatica...
