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 (optional) 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.
To lubricate sprocket tip:
Warning: wear heavy duty work gloves when handling the bar and chain.
Press 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.
Clean the guide bar sprocket tip.
Using the lube gun (optional), insert needle nose into the lubrication hole and inject grease
until it appears at outside edge of sprocket tip (Fig. 20).
Rotate saw chain by hand. Repeat lubrication procedure until the entire sprocket tip has
been greased.
12.3
Guide bar maintenance
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.
Warning: always wear protective gloves during maintenance operations. Do
not carry out maintenance when the engine is hot.
12.4
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 center. For non-experienced
users of the chain saw, we recommend to have the chain sharpened by a specialist in any
authorized service.
Warning: when having wrong sharpened chain, there may occur a higher
danger of kickback.
