BAR WEAR - Turn guide bar frequently at regular
intervals (for example, after 5 hours of use), to ensure
even wear on top and bottom of bar.
OIL PASSAGES - Oil passages on the bar should be
cleaned to ensure proper lubrication of the bar and chain
during operation.
NOTE: The condition of the oil passages can be easily
checked. If the passages are clear, the chain will
matically give off a spray of oil within seconds of starting
the saw. Your saw is equipped with an automatic oiler
system.
• 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 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
auto-
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 professional Service Center. If you feel
comfortable sharpening your own saw chain, special
tools are available from the professional Service Center.
