OPERATION

ADJUSTING IDLE SPEED

See Figure 28.

If the engine starts, runs, and accelerates but will not idle, turn the idle speed screw “ T ” clockwise to increase idle speed.

If the chain turns at idle, turn the idle speed screw “ T ” counterclockwise to reduce the idle RPM and stop the chain movement. If the saw chain still moves at idle speed, contact a Homelite Service Center for adjust- ment and discontinue use until the repair is made.

WARNING:

THE SAW CHAIN SHOULD NEVER TURN AT IDLE. Turn the idle speed screw “T” counterclockwise to reduce the idle RPM and stop the chain, or contact a Homelite Service Center for adjustment and discontinue use until the repair is made.

Serious personal injury may result from the saw chain turning at idle.

FELLING TREES

HAZARDOUS CONDITIONS

WARNING:

Do not fell trees during periods of high wind or heavy precipitation. Wait until the hazardous weather has ended.

When felling a tree, it is important that you heed the following warnings to prevent possible serious injury.

Do not cut down trees having an extreme lean or large trees with rotten limbs, loose bark, or hollow trunks. Have these trees pushed or dragged down with heavy equipment, then cut them up.

Do not cut trees near electrical wires or buildings.

Check the tree for damaged or dead branches that could fall and hit you during felling.

Periodically glance at the top of the tree during the backcut to assure the tree is going to fall in the desired direction.

If the tree starts to fall in the wrong direction, or if the saw gets caught or hung up during the fall, leave the saw and save yourself!
