Chain and BAR Lubrication

MAINTENANCE AND REPAIR INSTRUCTIONS

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).

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).

CAUTION: Never starve the bar and chain of lubrica-

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: A loose chain can jump off the bar while

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.

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: The Chain Brake® should not be used

for starting and stopping the saw during normal operation
