6.Pull the starter rope sharply with your right hand until the engine starts.

7.Allow the engine to run for approximately 30 seconds. Then, squeeze and release throttle trigger to allow engine to return to idle speed.

STARTING A WARM ENGINE

1.Move ON/STOP switch to the ON posi- tion.

2.Slowly press the primer bulb 6 times.

3.Pull the choke/fast idle lever out to the HALF CHOKE position.

4.Pull the starter rope sharply with your right hand until the engine starts.

5.Squeeze and release throttle trigger to allow engine to return to idle speed.

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, re- fer to the TROUBLESHOOTING TABLE.

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 authorized service dealer if any part is worn to less than 0,02″ (0,5

mm)thick. Repairs on a chain brake should be made by an authorized service dealer. Take your unit to the place of purchase if purchased from a servicing dealer, or to the nearest autho- rized master service dealer.

S This 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 acti- vated if the front hand guard is pushed for- ward, either manually or by centrifugal force.

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

S When cutting with the saw, the chain brake must be disengaged.

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 fol- lowing 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 top of the guide bar fall forward and contact the stump. When the tip of the bar hits the stump, the brake should activate.
