Checking the chain lubrication Never work with the chain saw withoute sufÞcient chain lubrication. 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. 15 cm above a trunk or the ground (use an appropriate base). If the lubrication is sufÞcient, you will see a light oil trace because oil will be ßung 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. 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. You can set the chain oil feed rate to minimum, moderate, and maximum feed rate. To adjust the supply rate, use a small screwdriver to turn the adjusting screw: • to the right for a faster • to the left for a slower oil feed rate. Pick one of the three settings depending on the length of the guide bar. While working make sure there is enough chain oil in the tank. If necessary, add oil. + - 1 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. 23 21
