152 3Checking the chain lubricationNever work with the chain saw without sufficient chain lubri-ca-tion. Otherwise the service life of the chain and guide bar willbe reduced. Before starting work check the oil level in the tankand the oil feed.Check the oil feed rate as described below:Start the chain saw (see ÑStarting the engineî).Hold the running chain saw approx. 15 cm above a trunk or theground (use an appropriate base).If the lubrication is sufficient, you will see a light oil trace be-cause oil will be flung off the sawing device. Pay attention to thedirection the wind is blowing and avoid unnecessary exposureto the oil spray!Note:After the saw has been turned off it is normal for residual chainoil to drip from the oil feed system, the guide bar and the chainfor a time. This does not constitute a defect!Place the saw on a suitable surface.CTo ensure troublefree operation of the oil pump the oil guidegroove at the crank case (2) and the oil inlet bore in the guidebar (3) must be cleaned regularly.Note:After the saw has been turned off it is normal for residual chainoil to drip from the oil feed system, the guide bar and the chainfor a time. This does not constitute a defect!Place the saw on a suitable surface.E1DAdjusting the chain lubricationThe 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 theadjusting screw in the following way:ï Turn to the right to reduce the feed rate.ï Turn to the left to increase the feed rate.Even very small adjustments to the adjusting screw (1) caninfluence the oil flow rate. While working make sure there isenough chain oil in the tank. If necessary, add oil.Adjustmentrange 70∞
