Checking the chain lubrication

Never work with the chain saw withoute sufficient chain lubri-

 

 

cation. Otherwisethe service life of the chain and guide bar will

I

, \ \

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

 

 

becauseoil 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 normalfor 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

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 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 beenturned off it is normalfor residualchain 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.
