3.Drain all bar and chain oil from tank into a container approved for oil.

4.Clean all foreign material from the saw.

5.Store it in a well-ventilated place that is inaccessible to children.

NOTE: Keep away from corrosive agents such as garden chemicals and de-icing salts.

Engine will not start.	1.	No spark.
(Make sure ignition switch
is in start position “I”.)
	2.	Flooded engine.

1.Check spark. Remove air filter cover. Remove sparking plug from cylinder. Reattach the sparking plug wire and lay sparking plug on top of cylinder with the metal part of plug touching the cylinder. Pull the starter rope and watch for spark at sparking plug tip. If there is no spark, repeat test with a new sparking plug.

Clean and reinstall sparking plug. Set ignition switch to run (I) position. Push and fully release primer bulb 7 times. Pull starter three times with choke lever at run. If engine does not start, move choke lever to choke and repeat normal starting procedure. If engine still fails to start, repeat procedure with a new sparking plug.
