If you have checked chain lubrication (see chapter "Guide
Bar, Saw Chain and Chain Sprocket") and found that no oil
is being delivered although the oil tank is full, switch off the
engine and start looking for the fault on the cutting attach-
ment.

Drain the chain oil tank. Remove the fastening screws!
and withdraw the oil pump.
If the oil pump is stuck, use a screwdriver to carefully pry it
away from the crankcase.
To do this, remove the chain sprocket cover, guide bar
and chain. Thoroughly clean the oil inlet holes as well
as the passage between the holes and the bar groove. Also
clean away dirt that may have collected at the end of the oil
hose and the area around it.
Pull off the hose" and remove the polymere disc#. Take
the filter$ off the stub. Now pull the cover% off the pump
housing, making sure that the diaphragm& does not stick
to the cover and tear.
Now check oil delivery again. If no oil emerges from
the hose , the oil pump must be removed from the
machine and cleaned.
Take the plunger and diaphragm & out of the pump
housing and remove the two gaskets ( Note the
spring ' between the pump housing and diaphragm. It
must not be lost.
Carefully wash the pump housing, cover, plunger with dia-
phragm and the filter in clean gasoline. Thoroughly clean
the gaskets and flange faces on the crankcase.
Reassemble the pump by reversing the above sequence.
Coat the plunger with a little lubricating oil before refitting.
