Otherwise the service life of the chain and guide bar will be reduced. Before starting work check the oil level in the tank and the oil feed. Check the oil feed rate as described below: Start the chain saw (see „Starting the engine”). Hold the running chain saw approx. 6" (15 cm) above a trunk or the ground (use an appropriate base). If the lubrication is sufficient, you will see a light oil trace because oil will be flung off the sawing device. Pay attention to the direction the wind is blowing and avoid unnecessary exposure to the oil spray! Note: 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 not constitute a defect! Place the saw on a suitable surface. 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. Note: 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 not constitute a defect! Place the saw on a suitable surface. E D Adjusting the chain lubrication The engine must be switched off. 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 the 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. Adjustment range 70° 25 Starting the engine Start the chain saw only after having assembled it completely 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. 2 4 3 1 6 5 A 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. 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 chain saw. Take the chain saw to a DOLMAR service center. 7 C B Cold.starting: Pull the choke (1) out until it audibly clicks. This simultane ously actuates the half-throttle lock. Move the I/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 center). Push the decompression 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 decompression 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 throttle stopper (5)) and tap the throttle lever (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. 26 E Working in winter In order to prevent carburetor icing in conditions of low temperature combined with high humidity, and below + 5°C in order to get up to operating temperature faster, heated air can be taken from the cylinder. Remove the filter hood (see „Cleaning air filter“) Remove the insert (10) and insert it as shown in position B for cold-weather operation. At temperatures above + 5°C the carburetor must NOT be fed heated air. Failure to follow these instructions can lead to damage to the cylinder and piston! At temperatures over +5°C place the insert in position A for normal operation. Position A - Normal operation Position B - Cold-weather operation Reinstall the filter hood.
