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 res ervoir up.

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
adjusting screw and turn in the desired direction
(there are three incremental settings):
(a) Clockwise-decrease lubrication.
(b)Counter clockwise-increase lubrication.
