Checking the chain lubrication

Never work with the chain saw without sufÞ cient chain lubri -ca-

tion. 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 sufÞ cient, you will see a light oil trace be-

cause oil will be ß ung 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.

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.

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

inß uence the oil ß ow rate. While working make sure there is

enough chain oil in the tank. If necessary, add oil.
