OPEN
■ After starting the engine,
gradually open choke by
pushing the choke knob and
finally keep it fully opened.
■ Do not fully open the choke
immediately when the engine is
cold or the ambient temperature
is low, because the engine may
stop.

Choke adjustment is
not necessary for the
auto-choke engine.
RUNNING
ACCELERATION LEVER
After the engine starts, set the
acceleration lever at the low
speed position and warm it up
without load for a few minutes.
Gradually move the acceleration
lever toward the high speed
position and set it at the required
engine speed.
TIP
Whenever high speed operation is
not required, slow the engine down
(idle) by moving the acceleration
lever to save fuel and extend
engine life.
