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
50 cm (20 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.
Rear handle should be gripped lightly with the
right hand.
WINTER OPERATION
