OPERATION

8.Pull STARTER until engine attempts to start.

Slowly pull the starter grip out for a short distance until you feel the starter engage, then briskly pull straight up. Do not pull to the end of the rope; this may damage the starter. Hold onto the grip during rewinding.

Pull the starter rope until the first firing of the engine is heard (no more than five pulls).

NOTE: A new unit may require additional pulls.

9.Push choke lever to half choke position.

10.Pull starter until engine runs.

NOTE: Allow the saw to run in this position 15-30 seconds, depending on the temperature.

11.Push choke lever all the way IN.

12.Immediately SQUEEZE and release the throttle trigger.

Immediately depress the throttle trigger, which releases the trigger lock button. Squeeze and release the throttle trigger to let the engine idle.

13.Move chain brake to RUN position.

Place chain brake lever/hand guard into the RUN position. Refer to “Operation – Operating the Chain Brake” later in this manual for additional information.

CAUTION:

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.

Now you are ready to pick up the saw. Use the proper grip for both handles. Refer to “Operation - Proper Grip on Handles” later in this manual for additional information.

STARTING A WARM ENGINE:

Follow the instructions for starting a cold engine (steps

1-9), but do not attempt to start in the full choke position (skip step 5). Push and release primer bulb 7 times. Pull the choke out and push back it in to the original run position.

STOPPING THE ENGINE

Release the throttle trigger and let the engine return to idle. To stop the engine, move the ignition switch to the “O” stop position. Do not put the chainsaw 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 “O” stop position, have the ignition switch repaired before using the chainsaw again to prevent unsafe conditions or serious injury.

Important: When you have finished using the saw, relieve tank pressures by loosening the CHAIN OIL and FUEL MIX caps. Then retighten the caps. Allow the engine to cool before storing.
