GUIDE bAR mAINtENANcE

Frequent lubrication of the guide bar (railed bar which
supports and carries the saw chain) sprocket tip is
required. Proper maintenance of the guide bar, as ex-
plained in this section, is essential to keep your saw in
good working condition.
Sprocket tip lubrication:
cAUtIoN: The sprocket tip on your
new saw has been pre-lubricated at the factory.
Failure to lubricate the guide bar sprocket tip as
explained below will result in poor performance
and seizure, voiding the manufacturer's
warranty. Lubrication of the sprocket tip is
recommended after 10 hours of use or once a
week, which ever occurs first. Always thoroughly
clean guide bar sprocket tip before lubrication.

tools for lubrication:
The lube gun (not included in the kit) is recommended
for applying grease to the guide bar sprocket tip. The
lube gun is equipped with a needle nose tip which
is necessary for the efficient application of grease to
the sprocket tip.
WARNING: Wear heavy duty work
gloves when handling the bar and chain.
1. Move the STOP switch down.
NotE. It is not necessary to remove the saw chain
to lubricate the guide bar sprocket tip. Lubrication
can be done on the job.

Most guide bar problems can be prevented merely
by keeping the chain saw well maintained.
Insufficient guide bar lubrication and operating the
saw with chain that is too tight will contribute to rapid
bar wear.
To help minimize bar wear, the following guide bar
maintenance procedures are recommended.
chain sharpening:
Chain sharpening requires special tools to ensure
that cutters are sharpened at the correct angle and
depth. For the inexperienced chain saw user, we
recommend that the saw chain be professionally
sharpened by the nearest professional service cen-
tre. If you feel comfortable sharpening your own saw
chain, special tools are available from the profes-
sional service centre.
