This does constitute a defect! Place the saw on a suitable surface. Adjusting the chain lubrication A The engine must be switched off. PTOP) W You can adjust the oil pump feed rate with the adjusting screw (1). The adjusting screw is on the bottom side of the housing. The oil pump comes factory-set to a medium feed rate. To change the feed quantity use a screwdriver and adjust the adjusting screw in the following way: Turn to the right to reduce the feed rate. - Turn to the left to increase the feed rate. Even very small adjustments to the adjusting screw (1) can influence the oil flow rate. While working make sure there is enough chain oil in the tank. If necessary, add oil. 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. After the saw has been turned off it is normal for residual chain oil to drip from the oil feed system, the guide bar and the chain for a time. This does constitute a defect! Place the saw on a suitable surface. 6 5 I BI A @ @ * Starting the engine Start the chain saw only after having assembled it com- pletely and inspected. Move at least 10 feet (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). 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. Cold-starting: Pull the choke (1)out until it audibly clicks. This simultaneously actuates the half-throttle lock. Move the l/STOP ignition switch (3) as shown by the arrow. Slowly pull out the starter cable until you notice resistance (the piston is positioned before the top dead centre). Push the starting valve (2) (option). Now pull the starter cable with a fast and forceful movement until you hear the first ignition. CAUTION: Do not pull out the starter cable more than approx. 50 cm, and lead it back by hand. Push the starting valve (2) (option). Depress the choke (1) and pull the starter cable again. As soon as the engine is running, grasp the rear handle (this actuates the grip safety (5)) and tap the throttle (6).This will release the half-throttle lock and the engine will run in 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 starting: As described for cold starting, except before starting pull the choke (1) all the way out and back in one time, in order to activate the half-throttle lock. Stopping the engine Move the I/STOP ignition switch to the "STOP" position. Checking the chain brake Do not work with the chain saw without first checking the chain brake1 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 my with one hand and hold thi e grip 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 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 chain saw. Take Adjusting the carburetor Important information: The carburetor of this tool is fitted with limiter caps which restrict the range of adjustment and prevents over-rich mixture settings. This ensures providing good engine power and efficient fuel consumption. Before installing the limiter caps, the manufacturer performs the "Basic Setting" procedure. 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. 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. 950 233 210) for optimum adjustment. Do not go below the specified basic setting of the main nozzle (H). Doing so may cause engine damage due to overheating and insufficient lubrication! Use the supplied carburetor screwdriver (8) for carburetor adjustment. It has a moulded-on projection that aids in adjusting. Before undertaking the adjustcent, run the engine for 3-5 minutes to warm it up, but not at high speed! For proper adjustment, proceed as follows: 1. Basic setting (engine off) Start engine and warm up. 2. Set idle 3. Check top speed 4. Check acceleration 5. Check idle speed Repeat steps 2-5 until you get the right idle speed, good acceleration and maximum per...
