AUTOMATIC CHAIN BRAKE

Kickback produced from the tip of the guide bar will

trip the automatic chain brake. To make sure that

the automatic chain brake operates properly, follow

these steps:

1. Stop the engine.

2. Hold the saw with the guide bar approximately

35 cm (14 in.) above a wooden surface. Right

hand should hold the rear handle, and left hand

should hold the front handle.

3. Release the front handle and drop the end of the

guide bar against the wooden surface.

4. The impact should lock the chain brake.

IMPORTANT

When checking the operation of the automatic

chain brake, use a soft surface substance like

wood to provide the impact so the chain is not

damaged.

WINTER OPERATION

Use the winter plug to prevent carburetor trouble in

winter.
