Checking the chain lubrication
Never work with the chain saw withoute sufficient chain lubri-
cation. 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.
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
because oil will be flung
off
the sawing device. Pay attention to
the direction the wind is blowing and avoid unnecessary
exposure to the oil spray!

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.
