NOTE:
● If the engine fails to start, release the
start switch, then push the start switch
again. Pause a few seconds before the
next attempt. Each cranking should be as
short as possible to preserve battery en-
ergy. Do not crank the engine more than
10 seconds on each attempt.
● If the battery is discharged, pull the recoil
starter to start the engine.

(choke) in position

the starter (choke) in position

the starter (choke) in this position to
warm up the engine.

idles smoothly and return the starter

To start a warm engine, refer to the “Starting a
cold engine” section. The starter (choke)
should not be used. The throttle should be
opened slightly.

Warming up
To get maximum engine life, always warm up
the engine before starting off. Never acceler-
ate hard with a cold engine! To see whether or
not the engine is warm, check if it responds to
the throttle normally with the starter (choke)
turned off.
