MAINTENANCE AND REPAIR INSTRUCTIONS
Breaking in a New Saw Chain
A new chain and bar will need chain readjustment after
as few as 5 cuts. This is normal during the break-in
period, and the interval between future adjustments will
begin to lengthen quickly.
WARNING:
from a loop of chain. This could cause dam-
age to the sprocket.
Chain Lubrication
Always make sure the automatic oiler system is working
properly. Keep the oil tank filled with Genuine Factory
Parts Chain, Bar and Sprocket Oil.
Adequate lubrication of the bar and chain during cutting
operations is essential to minimize friction with the guide
bar.
Never starve the bar and chain of lubricating oil.
Running the saw dry or with too little oil will decrease
cutting efficiency, shorten saw chain life, cause rapid
dulling of chain, and lead to excessive wear of bar from
overheating. Too little oil is evidenced by smoke or bar
discoloration.
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 Authorized Service Center. If you feel comfort-
able sharpening your own saw chain, special tools are
available from your Authorized Service Center.
CHAIN REPLACEMENT INFORMATION
There may be other quality equivalent replacement com-
ponents for achieving kickback protection.
