CHOKE (SIDE VIEW) chase if purchased from a servicing dealer, or to the nearest authorized master service dealer. Choke Knob OFF FULL STARTING A WARM ENGINE S Move ON/STOP switch to the ON position. S Push the choke knob in completely (to the OFF position). S Slowly press primer bulb 6 times. S Squeeze and hold throttle trigger. With thumb press fast idle lock down; then release throttle trigger. S Sharply pull the starter rope with your right hand until the engine starts. S 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 following the warm engine starting procedure listed above. Insure 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: WE DO NOT REP- RESENT AND YOU SHOULD NOT ASSUME THAT THE CHAIN BRAKE WILL PROTECT YOU IN THE EVENT OF A KICKBACK. Kickback is a lightning fast action which throws the bar and rotating chain back and up toward the operator. Kickback can be caused by allowing contact of the bar tip in the danger zone with any hard object. Kickback can also be caused by pinching the saw chain along the top of the guide bar. This action may push the guide bar rapidly back toward the operator. Either of these events may cause you to lose control of the saw which could result in serious injury or even death. DO NOT RELY UPON ANY OF THE DEVICES BUILT INTO YOUR SAW. YOU SHOULD USE THE SAW PROPERLY AND CAREFULLY TO AVOID KICKBACK. Reduced--kickback guide bars and low--kickback saw chains reduce the chance and magnitude of kickback and are recommended. Your saw has a low kickback chain and bar as original equipment. 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 1/32" thick. Repairs on a chain brake should be made by an authorized service dealer.

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. S When 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 procedure. This is the only instance when the saw should be placed on the ground with the engine running. Place the saw on firm ground. Hold the handles with both hands and apply full throttle. 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. 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. CUTTING METHODS IMPORTANT POINTS S Cut wood only. Do not cut metal, plastics, masonry, non-wood building materials, etc. S Stop the saw if the chain strikes a foreign object. Inspect the saw and repair or replace parts as necessary. S Keep 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.

CHAIN BRAKE
WARNING:
WE DO NOT REP-
RESENT AND YOU SHOULD NOT AS-
SUME THAT THE CHAIN BRAKE WILL
PROTECT YOU IN THE EVENT OF A
KICKBACK. Kickback is a lightning fast ac-
tion which throws the bar and rotating chain
back and up toward the operator. Kickback
can be caused by allowing contact of the bar
tip in the danger zone with any hard object.
Kickback can also be caused by pinching the
saw chain along the top of the guide bar. This
action may push the guide bar rapidly back
toward the operator. Either of these events
may cause you to lose control of the saw
which could result in serious injury or even
death. DO NOT RELY UPON ANY OF THE
DEVICES BUILT INTO YOUR SAW. YOU
SHOULD USE THE SAW PROPERLY AND
CAREFULLY TO AVOID KICKBACK.
Re-
duced--kickback guide bars and low--kick-
back saw chains reduce the chance and
magnitude
of
kickback
and
are recom-
mended. Your saw has a low kickback chain
and bar as original equipment.
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 1/32” thick. Repairs on a chain
brake should be made by an authorized ser-
vice dealer. Take your unit to the place of pur-
chase if purchased from a servicing dealer,
or to the nearest authorized master service
dealer.
