BAR GROOVES
Bar grooves (or rails which support and carry the chain)
should be cleaned if the saw has been heavily used or if
the saw chain appears dirty. Rails should always be
cleaned every time the saw chain is removed.
TO CLEAN GUIDE BAR RAILS:
1.
Remove sprocket cover, bar and chain. Refer to Saw
Chain Replacement / Installation.
2.
Using a screwdriver, putty knife, wire brush or other
similar instrument, clear residue from the rails on the
guide bar (Fig. 6).
This will keep the oil passages open to provide prop-
er lubrication to the bar and chain.
3.
Reinstall the bar, chain and bar bolt retaining nuts.
Refer to Saw Chain Replacement / Installation.

OIL PASSAGES
Oil passages at bar pad 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.

CHAIN MAINTENANCE
WARNING: Unless you have experience and
specialized training for dealing with kickback
(see Important Safety Instructions), always
use a low-kickback saw chain, which signifi-
cantly 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.
A low-kickback saw chain should always be used in con-
junction with other kickback protection devices such as
the hand guard, which is furnished with your unit.
Always use a replacement saw chain designed as "low-
kickback" or a saw chain which meets the low-kickback
performance.
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.
Low-Kickback Saw Chain
A low-kickback saw chain is a chain which has met the
kickback performance requirements of ANSI B175.1. Do
not use other replacement chain unless it has met these
requirements for your specific model.
By keeping the 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.
WARNING: Never remove, modify or make
inoperative any safety device furnished with
your unit. The hand guard and low-kickback
saw chain are major safety features provided
for your protection.
WARNING: Ensure that the unit is off and the
spark plug is disconnected (for gas power-
heads) when working on the saw chain. Wear
heavy duty gloves too.
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. Refer to Saw Chain
Tension Adjustment.
BREAKING IN A NEW SAW CHAIN
A new chain and bar will need 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 possi-
ble to obtain correct chain tension adjustment, a link will
have to be removed to shorten the chain. See your Troy-
Bilt Authorized Service Center to have this repair per-
formed.
WARNING: Never use a loop of chain that
has more than 3 links removed from it. This
could damage the sprocket.
