To stop the engine, move the ON/STOP

switch to the STOP position.

To start the engine, hold the saw firmly on

the ground as illustrated below. Make sure

the chain is free to turn without contacting

any object.

Hold saw firmly while pulling starter rope.

Use only 15″ --- 1 8 ″ of rope per pull.

IMPORTANT POINTS TO REMEMBER

Whenpulling thestarterrope,donotuse thefull

extent ofthe rope as this can cause the ropeto

break. Do not let starter rope snap back. Hold

the handle and let the rope rewind slowly.

For cold weather starting, start the unitat full

choke; allow the engine to warm up before

squeezing the throttle trigger.

NOTE:Donotcut materialwith thechoke/fast

idle lever at the FULL CHOKE position.

STARTING A COLD ENGINE (or a

warm engine after running out of

fuel)

NOTE

:Inthefollowingsteps,whenthecho-

ke/fast idle lever is pulled out to the full ex-

tent, the correct throttle setting for starting is

set automatically.

DIFFICULT STARTING (or starting a

flooded engine)

The engine may be flooded with too much

fuel if it has not started after 10 pulls.

Flooded engines can be cleared of excess

fuel by pushing the choke/fast idle lever in

completely (to the OFF CHOKE position)

and then following the warm engine starting

procedure listed above. Ensure the ON/

STOP switch is in the ON position.

Startingcouldrequire pullingthe starterrope

handle many times dependingon how badly

the unit is flooded. If engine fails to start, re-

fer to the TROUBLESHOOTING TABLE.
