Failure to release partial throttle when chain brake lever is in the brake position will result in serious damage to the unit. Never squeeze and hold the throttle trigger while the chain brake is in the brake position.

To Start a Warm Engine:

nSet the ignition switch to the RUN ( I ) position.

nMake sure the chain brake is in the run position by pulling back on the lever/hand guard.

nFully press and release the primer bulb 7 times.

nPull choke lever half way out to HALF CHOKE position.

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.
