Brake function test:
The chain brake must be checked several times daily. Place the
saw on firm ground. Keep a firm grip on the saw with your right
hand on the rear handle and your left hand on the front handle,
and with your thumbs and fingers encircling both handles squeeze
the trottle. Then activate the chain brake by turning your left wrist
against the hand guard without releasing your grip on the front
handle. The chain should stop immediately (illustr.).
Inertia-activation function test
The chain brake must be checked several times daily. Hold the
chain saw approximately 18 inches (45 cm) above a trunk or
other firm wooden object. Release your grip on the front handle
and let the saw fall, rotating around the rear handle. When the
tip of the guide bar hits the trunk, the brake should activate.
IMPORTANT!
Failure to check and maintain the chain brake may result in the
failure of the chain brake to activate in the event of a kickback.
CAUTION!
Always disconnect power cable before fitting parts or performing
adjustments.
WARNING!
Dirt and wear effect brake funktion. Follow all maintenance
instructions carefully. If anything about your chain brake is not in
order, contact your service dealer.
Maintenance:
With the motor shut off, move front hand guard back and forth
to ensure that the mechanism works freely and that the brake is
activated. If necessary, clean resin and chips from the brake.
Lubricate the mechanism and bearing surfaces with oil. Check
that the brake band is at least 0.65 mm (0.026 in) thick where
most worn.
Motor overload protection
The saw is equipped with a slipping clutch which protects it from
overload.
If the chain stops while the motor is running, the saw is overloaded.
Ease up on the cutting pressure until the chain begins to turn
again. If the blade has jammed, stop the saw immediately and
free the blade. If the chain stops frequently while cutting, it may
be due to a dull chain. If so, stop and sharpen the chain.
