4-1. TO START SAW

1.Make sure the CHAIN BRAKE® IS DISENGAGED. The motor will not start if the CHAIN BRAKE® is in the ENGAGED position. Disengage the CHAIN BRAKE® by pulling backward toward the motor (Figure 4-1A).

WARNING

Ensure the extension cord is of the proper size and type for your saw.

2.An extension cord retainer (A) (Fig. 4-1B) is built into the rear handle that prevents the extension cord from pulling out of the handle. To use this feature, simply double the extension cord, about a foot from the end, and insert it through the hole at the end of the handle. Hook the loop formed by doubling the cord over the tab. Gently tug on the cord to ensure that it is firmly retained in the saws handle. Plug the receptacle end of the extension cord into the tool’s power supply cord.

WARNING

Make sure the extension cord does not come in contact with the guide bar and saw chain.

3.Grip the saw with both hands, left hand holding the front handle (DO NOT HOLD CHAIN BRAKE®) and the right hand holding the rear handle. Thumbs and fingers should encircle both handles (Figure 4-1C).

4.With your RIGHT THUMB, depress the LOCK/OFF button on the top of the rear handle, and at the same time squeeze the trigger. To stop the saw, release the trigger (Figure 4-1D).

NOTE: It is not necessary to maintain pressure on the LOCK/OFF button once the trigger is squeezed and the motor is running. The LOCK/OFF button is a safety device to avoid accidental starting.

4-2.TO STOP MOTOR

The saw motor will automatically stop when the trigger is released. The LOCK/OFF button will have to be depressed and the trigger squeezed to restart the motor.

4-3. 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.

The oil tank level can be checked in the inspection slot (A) provided on the right side of the saw. Tank is full when oil is at the top of the slot (Figure 4-3A).

CAUTION

Never starve the bar and chain of lubrication 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 evidenced 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 normal. See Section 3-4, Saw Chain Tension Adjustment instructions.

WARNING / CAUTION

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.

4-4. CHAIN BRAKE® / HAND GUARD

This McCulloch 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 disengaged (chain can move) when the brake is pulled back and locked. This is the normal run- ning position (Figure 4-4A).

The CHAIN BRAKE® is engaged (chain cannot move) when the brake is in forward position (Figure 4-4B).

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.

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 imme- diately 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.
