12.6 Chain maintenance
Chain tension:
Check the chain tension frequently and adjust as often as necessary to keep the chain snug
on the bar, but loose enough to be pulled around by hand.
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: never have more than 3 links removed from a loop of chain. This
could cause damage to the sprocket.
Chain lubrication:
Always make sure the automatic oiler system is working properly. Keep the oil tank filled with
good quality 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:
For the inexperienced chain saw user, we recommend that the saw chain be professionally
sharpened by the nearest professional service centre. If you feel comfortable sharpening your
own saw chain, special tools are available from the professional service centre.
