MAINTENANCE AND REPAIR INSTRUCTIONS
Never have more
than 3 links
removed from a loop of chain. This could
cause damage to the sprocket.
WARNING:
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
comfortable sharpening your own saw chain, special
tools are available from your Authorized Service Center.
CHAIN MAINTENANCE
A low-kickback saw chain should always be used in
conjunction with other kickback protection devices such
as the Chain Brake®/Hand Guard furnished with your unit.
Always use a replacement saw chain designed as “low-
kickback” or a saw chain which meets the low-kickback
performance requirements of ANSI (American National
Standards Institute).
A standard saw chain (a chain which does not have the
kickback reducing guard links) should only be used by an
experienced professional chain saw operator.
What is a Low-Kickback Saw Chain?
A low-kickback saw chain is a chain which has met the
kickback performance requirements of ANSI B175.1.
By keeping the Chain Brake® and saw chain in good
working condition and correctly serviced as
recommended in this manual, you will be able to
maintain the safety system of your chain saw over the life
of the product.
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.
Over a period of time, however, the moving parts of the
saw chain will become worn, resulting in what is called
CHAIN STRETCH. This is normal. When it is no longer
possible to obtain correct chain tension adjustment, a
link will have to be removed to shorten the chain. See
your Authorized Service Center to have this repair
performed.
Unless you have
experience and
specialized training for dealing with
kickback (see Safety Precautions), always
use a low-kickback saw chain, which
significantly reduces the danger of
kickback. Low-kickback saw chain does
not completely eliminate kickback. A low-
kickback or “safety chain”, should never be
regarded as total protection against injury.
WARNING:
Never remove,
modify or make
inoperative any safety device furnished with
your unit. The Chain Brake® / Hand Guard
and low-kickback saw chain are major
safety features provided for your protection.
WARNING:
CHAIN REPLACEMENT INFORMATION
There may be other quality equivalent replacement
components for achieving kickback protection.
