WARNING:
If the saw is operated
with a loose chain, the chain could jump
off the guide bar and result in serious in-
jury.
CHECK CHAIN SHARPNESS
A sharp chain makes wood chips. A dull
chain makes a sawdust powder and cuts
slowly. See
CHAIN SHARPENING

SERVICE AND ADJUSTMENTS

CHECK GUIDE BAR
Conditions which require guide bar main-
tenance:
S Saw cuts to one side or at an angle.
S Saw has to be forced through the cut.
S Inadequate supply of oil to the bar and
chain.
Check the condition of the guide bar each
time the chain is sharpened. A worn guide
bar will damage the chain and make cut-
ting difficult.
After each use, with unit disconnected
from power source, clean all sawdust from
the guide bar and sprocket hole.
To maintain guide bar:
S Disconnect the chain saw from the pow-
er source.
S Loosen and remove bar clamp nuts.
Remove bar and chain from saw.
SERVICE AND ADJUSTMENTS
CHAIN SHARPENING
WARNING:
Improper chain sharp-
ening techniques and/or depth gauge
maintenance will increase the chance of
kickback which can result in serious injury.
WARNING:
Wear
gloves when handling chain. The chain
is sharp and can cut you even when it is
not moving.
S Clean the oil holes and bar groove after
each 5 hours of operation.
S Burring of guide bar rails is a normal
process of rail wear. Remove these
burrs with a flat file.
S When rail top is uneven, use a flat file to
restore square edges and sides.
Worn Groove
Replace the guide bar when the groove is
worn, the guide bar is bent or crack--ed, or
when excess heating or burring of the rails
occurs. If replacement is necessary, use
only the guide bar specified for your saw in
the repair parts list or on the decal located
on the chain saw.

Bar Oil Fill Cap
S Check bar and chain oil before use and
every 15 minutes while operating the
saw. See

INSPECT AND CLEAN UNIT AND
LABELS
S After each use, inspect complete unit for
loose or damaged parts. Clean the unit
and labels using a damp cloth with a
mild detergent.
S Wipe off the unit and labels with a clean
dry cloth.
Conditions which indicate the need for
chain sharpening:
S Reduction in size of wood chips. The
size of the wood chip will decrease as
the chain gets duller until it becomes
more like a powder than a chip. Note
that dead or rotted wood will not pro-
protective
duce a good chip.
S Saw cuts to one side or at an angle.
