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 mainte-
nance procedures are recommended.
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.
BAR GROOVES (B) Bar grooves (or rails which support
and carry the chain) should be cleaned if saw has been
used heavily or if saw chain appears dirty. Rails should
always be cleaned every time saw chain is removed.

OIL PASSAGES (A) Oil passages on the bar should be
cleaned to ensure proper lubrication of the bar and chain
during operation. This can be done using a soft wire small
enough to insert into the oil discharge hole.

NOTE: The condition of the oil passages can be easily

checked. If the passages are clear, the chain will
automatically 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.

MAINTENANCE AND REPAIR INSTRUCTIONS

Never have more
than 3 links removed

from a loop of chain. This could cause dam-
age to the sprocket.

WARNING:

INERTIA CHAIN BRAKE® ACTION

NOTE: THIS SAW IS EQUIPPED WITH AN INERTIA

CHAIN BRAKE. IF THE SAW KICKS BACK WHILE
IN USE, THE INERTIA OF THE MOVING SAW
WILL ACTIVATE THE BRAKE. A BRAKE BAND
AROUND THE CLUTCH DRUM ACTIVATES AND
STOPS THE MOVING CHAIN.

CHAIN REPLACEMENT INFORMATION

Chain Lubrication

Always make sure the automatic oiler system is working
properly. Keep the oil reservoir filled with Chain, Bar and
Sprocket Oil.
Adequate lubrication of the bar and chain during cutting oper-
ations 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 effi-
ciency, 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 cut-
ters 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 comfortable sharp-
ening your own saw chain, special tools are available from
your Authorized Service Center.
