14 CLEANING AND MAINTENANCE
Always pull the plug out of the power socket before doing any work on the
chainsaw!
Keep the cooling vents on the motor housing clean and unobstructed at all times.
Only the maintenance work described in these operating instructions may be carried out.
Any other maintenance work must be carried out by our Customer Service.
Do not modify the power saw in any way as this could jeopardize its safety.
Should the chainsaw fail despite our careful manufacturing and inspection procedures,
have it repaired by an authorized Customer Service work-shop.
14.1
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.
14.2
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 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.
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.
Rotate saw chain by hand. Repeat lubrication procedure until the entire sprocket tip has
been greased.
14.3
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.
