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

7.Allow the engine to run for approximately 5 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.Pull the choke/fast idle lever out to the HALF CHOKE position.

3.Slowly press the primer bulb 6 times.

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, refer to the TROUBLESHOOTING TABLE or call 1-800-554-6723.

CHAIN BRAKE

CUTTING METHODS 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.

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

IMPORTANT POINTS 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 inches (35 cm) above a stump or other wooden surface. Re- lease 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.

CUTTING METHODS

IMPORTANT POINTS

SCheck chain tension before first use and after 1 minute of operation. See CHAIN

TENSION in the ASSEMBLY section.

SCut wood only. Do not cut metal, plastics,

masonry, non-wood building materials, etc.

SStop the saw if the chain strikes a foreign object. Inspect the saw and repair or re- place parts as necessary.

SKeep the chain out of dirt and sand. Even a

small amount of dirt will quickly dull a chain and thus increase the possibility of kickback.

SPractice cutting a few small logs using the following techniques to get the “feel” of us- ing your saw before you begin a major sawing operation.

S Squeeze the throttle trigger and allow the engine to reach full speed before cutting.

S Begin cutting with the saw frame against the log.

S Keep the engine at full speed the entire time you are cutting.

S Allow the chain to cut for you. Exert only light downward pressure. If you force the cut, damage to the bar, chain, or en- gine can result.
