DIFFICULT STARTING (or starting a flooded engine)

The engine may be flooded with too much fuel if it has not started after 10 pulls. Flooded engines can be cleared of excess fuel by pushing the choke/fast idle lever in completely (to the OFF CHOKE position) and then following the warm engine starting procedure listed above. Ensure the ON/ STOP switch is in the ON position.

Starting could require pulling the starter rope handle many times depending on how badly the unit is flooded. If engine fails to start, refer to the TROUBLESHOOTING TABLE or call 1-800-554-6723.

CHAIN BRAKE

WARNING: If the brake band is worn too thin it may break when the chain brake is triggered. With a broken brake band, the chain brake will not stop the chain. The chain brake should be replaced by an autho- rized service dealer if any part is worn to less than 0.020(0.5 mm) thick. Repairs on a chain brake should be made by an autho- rized service dealer. Take your unit to the place of purchase if purchased from a ser- vicing dealer, or to the nearest authorized master service dealer.

SThis saw is equipped with a chain brake. The brake is designed to stop the chain if kickback occurs.

S The inertia--activated chain brake is activated if the front hand guard is pushed forward, either manually (by hand) or automatically (by sudden movement).

S If the brake is already activated, it is disengaged by pulling the front hand guard back toward the front handle as far as possible.

SWhen cutting with the saw, the chain brake must be disengaged.

Disengaged

Engaged

Braking function control CAUTION: The chain brake must be

checked several times daily. The engine must be running when performing this proce- dure. This is the only instance when the saw should be placed on the ground with the en- gine running.

Place the saw on firm ground. Grip the rear handle with your right hand and the front han- dle with your left hand. Apply full throttle by fully depressing the throttle trigger. Activate the chain brake by turning your left wrist against the hand guard without releasing your grip around the front handle. The chain should stop immediately.

Inertia activating function control

WARNING: When performing the following procedure, the engine must be turned off.

Grip the rear handle with your right hand and the front handle with your left hand. Hold the chain saw approximately 14(35 cm) above a stump or other wooden surface. Release your grip on the front handle and use the weight of the saw to let the tip of the guide bar fall forward and contact the stump. When the tip of the bar hits the stump, the brake should activate.
