manual abstract


The next time you use the saw, fill 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. I t-1waste oil & u A - & chain oil fuelloil mixture B NEVER USE WASTE OIL Waste oil is very dangerous for the environment. Waste oil contains high amounts of carcinogenic substances. Residues in waste oil result in a high degree of wear and tear at the oil pump and the sawing device. 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. 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! Refuelling FOLLOW THE SAFETY PRECAUTIONS! Be careful and cautious when handling fuels. The engine must be switched off! Thoroughly clean the area around the caps, to prevent dirt from getting into the fuel or oil tank. Unscrew the cap and fill the tank with fuel (fuel/oil mixture) or chain oil as the case may be. Fill up to the bottom edge of the tiller neck. Be careful not to spill fuel or chain oil! Tightly screw on the cap. Clean screw cap and tank after refuelling. Lubricating the chain During operation there must always be sufficient chain oil in the chain-oil tank to provide good chain lubrication. One filling is sufficient for about one half-hour of continuous operation. Checking the chain lubrication Never work with the chain saw withoute sufficient chain lubri- cation. 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. ,\ \ I 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 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.
