12 MAINTENANCE
12.1
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 explained in this section, is
essential to keep your saw in good working condition.
12.2
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.
