8. Operation
Adjusting Oil Flow Rate
WARNING
Never fill the oil reservoir nor adjust the oiler with
the engine running.
IMPORTANT
An increase in bar oil flow rate will speed oil consump-
tion, requiring more frequent checks on the oil reservoir.
To ensure sufficient lubrication, it may be necessary to
check the oil level more frequently than at fuel tank
refills.
The guide bar and chain are lubricated automatically
by a pump that operates whenever the chain rotates.
The pump is set at the factory to deliver a minimum flow
rate, but it can be adjusted in the field. A temporary
increase in oil flow is often desirable when cutting things
like hardwood or wood with a lot of pitch.
Adjust the pump as follows:
1. Stop the engine and make sure the stop switch is in
the OFF position.
2. Place the unit on its side with the oil reservoir up.
(1) Oil tank
GB-12
(2) Chain cover
IMPORTANT
The oil flow adjusting screw must be pressed in slightly
in order to turn. Failure to do so could damage the pump
and screw.
3. With a screwdriver, push in on the oil flow rate adjust-
ing screw and turn in the desired direction (there are
three incremental settings):
(a) Clockwise-decrease lubrication
(b) Counter clockwise-increase lubrication
(c) Middle
WARNING
• Always wear work gloves made of leather or some
other sturdy material when using the pruner.
• Falling branches may fall onto the face or into the
eyes, resulting in injuries, scratches, and cuts,
and for this reason you should always be sure to
wear a helmet and face protector when using your
pruner.
