The chain saw’s lubrication system should ensure
that the bar and chain receive an effective and
adequate lubrication during different operating
conditions and engine speeds.
The operation of the oil pump can take place either
via the clutch drum or directly by the crankshaft. In
the former case the pump is stopped during idling
(no unnecessary oil consumption) and in the latter
case it works continuously.
The lubrication system passages are small and
sensitive to dirt, which can result in the stop-
page of the oil flow. It is therefore of the greatest
importance that the passages and filter are
carefully cleaned during service work.
If the capacity of the oil pump is adjustable it is
important that the pump setting is checked
after service.

The design of the oil pump is basically the
same for all these saw models.
Remove the screws which hold the oil
pump and guard plate over the bar attach-
ment.
Lift off the oil pump cover and pump shaft
(1), and the rubber connection (2) at the
bar attachment.
Dismantle the pump gear by means of
extractor No. 530 03 11-36 and

Screw the extractor on the pump gear as
far as possible and pull off the wheel.
