TO LUBRICATE SPROCKET TIP:
WARNING
Wear heavy duty work gloves when
performing this application
to reduce risk of personal injury,
1, Unplug the chain saw from the power
source.
NOTE: It is not necessary to remove the
saw chain to lubricate the guide bar
sprocket tip. Lubrication can be done on
the job,
2
. Clean the guide bar sprocket tip.
Using disposable Lube gun, insert tip
of lube gun into the lubrication hole and
inject grease until it appears at the
outside edge of the sprocket tip (Figure
6-1 A).
Make sure that the CHAIN BRAKE® is
deactivated. Rotate the saw chain by
hand. Repeat the lubrication procedure
until the entire sprocket tip has been
greased.

aUlDE BAR MAINTENANCE
Most guide bar problems can be prevented
merely by keeping the chain saw well
maintained.
Incorrect filing and non-uniform cutter and
depth gauge settings cause most guide bar
problems, primarily resulting in uneven bar
wear. As the bar wears unevenly, the rails
widen, which may cause chain clatter and
difficulty in making straight cuts.
Insufficient guide bar lubrication and
operating the saw with a chain that is TOO
TIGHT will contribute to rapid bar wear
(see Section 6-2).
To help minimize bar wear, the foiiowing
guide bar maintenance is 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 - 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.
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,
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.
TO CLEAN GUIDE BAR RAILS:
1. Remove sprocket cover, bar and chain,
(see Section 3-3)
2. Using a screwdriver, putty knife, wire
brush or other similar instrument, clear
residue from the rails on the guide bar.
This will keep the oil passages open to
provide proper lubrication to the bar
and chain (Figure 6-1B).
3. Reinstall the bar, chain, sprocket cover
and bar bolt knob. (See Section 3-3),
6-2. CHAIN MAINTENANCE
INSTRUCTIONS
WARNING
Unless you have experience and specializ­
ed training for dealing with kickback (see
Safety Precautions), always use a low-
kickback saw chain, which significantly
reduces the danger of kickback. Low-kick-
back 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 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 iow-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 experien­
ced professional chain saw operator.
