technician.
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.
1. Dismount the Saw Chain (1) and Guide Bar (2) by following the instructions in
‘Assembling the chainsaw’ in reverse
2. Remove saw dust from the bar groove and oiling port using a small screwdriver, probe
(not included) (see Fig. 19), or compressed air
3. Inspect the Guide Bar and the sprocket on its tip. Lubricate the sprocket with a suitable
maintenance spray
4. Deburr, turn over or replace the Guide Bar as required
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.
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
