This latches the trigger for starting. n Pull starter grip until engine runs. n Push choke lever all the way in to the RUN position. n Squeeze and release the throttle trigger to return the engine to idle. STOPPING THE ENGINE See Figures 12 - 13. Release the throttle trigger and let the engine return to idle. To stop the engine, move the ignition switch to the STOP () position. Do not put the chain saw on the ground when the chain is still moving. For additional safety, set the chain brake when the saw is not in use. In the event that the ignition switch will not stop the saw, pull the choke lever out to the fully extended position (FULL CHOKE / ) and engage chain brake to stop the engine. If the ignition switch will not stop the saw when set to the STOP position, have the ignition switch repaired before using the chain saw again to prevent unsafe conditions or serious injury. NOTE: When you are finished using the saw, always relieve tank pressure by loosening, then retightening, the chain oil and fuel mix caps. Allow the engine to cool before storing. OPERATION TRIGGER RELEASE 1 3 THROTTLE LOCK BUTTON THROTTLE TRIGGER 2 Fig. 11 IGNITION SWITCH IN THE STOP POSITION Fig. 12 BRAKE POSITION Fig. 13 OPERATION ADJUSTING IDLE SPEED See Figure 14. n If the engine starts, runs, and accelerates, but will not idle, turn the idle speed screw “T” clockwise to increase idle speed. n If the chain turns at idle, turn the idle speed screw “T” counterclockwise to reduce the idle RPM and stop the chain movement. If the saw chain still moves at idle speed, contact an authorized service center for adjustment and discontinue use until the repair is made. WARNING: THE SAW CHAIN SHOULD NEVER TURN AT IDLE. Turn the idle speed screw “T” counterclockwise to reduce the idle RPM and stop the chain, or contact an authorized service center for adjustment and discontinue use until the repair is made. Serious personal injury may result from the saw chain turning at idle. PULL AND PUSH See Figure 15. The reaction force of the saw is always opposite to the direction the chain is moving. Thus, the operator must be ready to control the PULL when cutting on the bottom edge of the bar and the PUSH when cutting along the top edge. NOTE: The chain saw has been fully factory tested. It is normal to find some slight oil residue on the saw. WARNING: KICKBACK occurs when the moving chain contacts an object at the upper portion of the tip of the guide bar or when the wood closes in and pinches the saw chain in the cut. Contact at the upper portion of the tip of the guide bar can cause the chain to dig into the object and stop the chain for an instant. The result is a lightning-fast reverse reaction which kicks the guide bar up and back toward the operator. If the saw chain is pinched along the top of the guide bar, the guide bar can be driven rapidly back toward the operator. Either of these reactions can cause loss of saw control, which can result in serious injury. Do not rely exclusively upon the safety devices built into the saw. As a chain saw user, you should take steps to keep your cutting jobs free from accident or injury. See General Safety Rules for more details. IDLE SPEED SCREW “T” Fig. 14 PULL PUSH Fig. 15 KICKBACK PRECAUTIONS See Figures 16 - 17. Rotational kickback occurs when the moving chain contacts an object at the Kickback Danger Zone of the guide bar. The result is a lightning-fast reverse reaction, which kicks the guide bar up and back towards the operator. This reaction can cause loss of control, which can result in serious injury. PREPARING FOR CUTTING PROPER GRIP ON HANDLES See Figure 18. See General Safety Rules for appropriate safety equipment. n Wear non-slip gloves for maximum grip and protection. n Hold the saw firmly with both hands. Always keep your left hand on the front handle and your right hand on the rear handle so that your body is to the left of the chain line. WARNING: Never use a left-handed (cross-handed) grip or any stance that would place your body or arm across the chain line. n Maintain a proper grip on the saw whenever the engine is running. The fingers should encircle the handle and the thumb is wrapped under the handlebar. This grip is least likely to be broken by a kickback or other sudden reaction of the saw. Any grip in which the thumb and fingers are on the same side of the handle is dangerous because a slight kick of the saw can cause loss of control. OPERATION KICKBACK DANGER ZONE Fig. 16 ROTATIONAL KICKBACK Fig. 17 PROPER HAND GRIP POSITION PROPER GRIP IMPROPER GRIP CHAIN LINE WARNING: DO NOT operate the throttle trigger with your left hand and hold the front handle with your right hand. Never allow any part of your body to be in the chain line while operating a saw. Fig. 18 PROPER CUTTING STANCE See Figure 19. ..n Balance your weight with both feet on solid ground. n Keep left arm with elbow locked in a “straight arm” position to withstand any kickback force. n Keep your body to the left of the ...
