MAINTENANCE AND REPAIR INSTRUCTIONS
CHAIN AND BAR LUBRICATION
Adequate lubrication of the saw chain during cutting oper-
ations is essential to minimize friction with the guide bar.
Your chain saw is equipped with an automatic oiler system.
The oiler automatically delivers the proper amount of oil to
the bar and chain. There is no flow adjustment.
You can check the oil reservoir level using the oil reservoir
window (D) provided on the right side of the saw. The
reservoir is full when oil is at the top of the window (Fig.
25).
D
CAUTION:
tion oil. Running the saw DRY or with TOO
LITTLE OIL will decrease cutting efficiency,
shorten chain saw life, and cause rapid
dulling of the chain and excessive wear of
the bar from overheating. Too little is evi-
denced by smoke or bar discoloration.
NOTE: The saw chain stretches during use, particularly
when it is new, and occasional adjustment will be
needed. A new chain requires more frequent
adjustment during the break-in period. This is nor-
mal. See Section Saw Chain Tension Adjustment
for instructions.
WARNING:
you are cutting, as well as wear the bar and
chain. A chain that is too tight can damage
the saw. Either situation, chain too loose or
too tight, could cause serious personal injury.
CHAIN BRAKE® / HAND GUARD
This chain saw is equipped with chain brake/hand guard.
The Hand Guard protects your left hand in the event it
slips off the front handle.

A loose chain can

The Chain Brake® is a safety feature which is activated if
pressure is applied against the guard or when, in the
event of kickback, the operator's hand strikes the lever.
When the Chain Brake® is activated, chain movement
abruptly stops and the power supply to the motor is
immediately cut off.
The purpose of the Chain Brake® is to reduce the possi-
bility of injury due to kickback. The Chain Brake® cannot,
however, provide the measure of intended protection if the
saw is carelessly operated.
The Chain Brake® is disengaged (chain can move) when
the brake is pulled back and locked. This is the normal
running position (Fig. 26).
The Chain Brake® is engaged (chain cannot move) when
the brake is in forward position (Fig. 27).
NOTE: The motor will not start if the Chain Brake® is in
the engaged position.
CAUTION:
for starting and stopping the saw during
normal operation
