Take your unit to the place of purchase if purchased from a servicing dealer, or to the nearest authorized 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 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 STARTING A WARM ENGINE 1. Move ON/STOP switch to the ON position. 2. Pull the choke/fast idle lever out to the HALF CHOKE position. 3. Pull the starter rope quickly with your right hand until the engine starts. 4. Squeeze and release the throttle trigger to allow engine to return to idle speed. DIFFICULT STARTING (or starting a flooded engine) The engine may be flooded 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. Ensure the ON/STOP switch is in the ON position. Starting could require many pulls depending on how badly unit is flooded. If engine still fails to start, refer to 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 authorized service dealer if any part is worn to less than 0.020″ 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. Grip the rear handle with your right hand and the front handle 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. CUTTING METHODS IMPORTANT POINTS S Check chain tension before first use and after 1 minute of operation. See CHAIN TENSION in the ASSEMBLY section. 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. 10
