WARNING:
When starting engine,
hold the unit as illustrated. Do not set unit on
any surface except a clean, hard area when
starting engine or while engine is running. De-
bris such as gravel, sand, dust, grass, etc.
could be picked up by the air intake and
thrown out through the discharge opening,
damaging the unit or property, or causing seri-
ous injury to bystanders or the operator.
STARTING A COLD ENGINE (or a

4. Pull starter rope handle sharply until engine
sounds as if it is trying to start, but do not pull
rope more than 6 times.
5. As soon as engine sounds as if it is trying to
start, move choke lever to HALF CHOKE
position.
6. Pull starter rope sharply until engine runs,
but no more than 6 pulls. NOTE: If the en-
gine doesn’t start after 6 pulls (at the HALF
CHOKE position), move the choke lever to
the FULL CHOKE position and press the
primer bulb 6 times. Squeeze and hold the
throttle trigger and pull the starter rope 2
more times. Move the choke lever to the
HALF CHOKE position and pull the starter
rope until the engine runs, but no more
than 6 pulls. If the engine still doesn’t start,
it is probably flooded. Proceed to START-
ING A FLOODED ENGINE.
7. Once the engine starts, allow it to run 10 se-
conds, then move the choke lever to the
RUN position. Allow the unit to run for 30
more seconds at RUN before releasing the
throttle trigger. NOTE: If engine dies with
the choke lever in the RUN position, move
the choke lever to the HALF CHOKE posi-
tion and pull the rope until engine runs, but
no more than 6 pulls.
STARTING A WARM ENGINE
1. Move the choke lever to the HALF CHOKE
position.
2. Squeeze the throttle trigger fully and hold
through all remaining steps.
3. Pull starter rope sharply until engine runs,
but no more than 6 pulls.
4. Allow engine to run 15 seconds, then move
the choke lever to RUN.
NOTE: If engine has not started, pull starter
rope 5 more pulls. If engine still does not run, it
is probably flooded.
STARTING A FLOODED ENGINE
Flooded engines can be started by placing the
choke lever in the RUN position; then, pull the
rope to clear the engine of excess fuel. This
could require pulling the starter handle many
times depending on how badly the unit is
flooded. If the unit still doesn’t start, refer to
TROUBLESHOOTING TABLE.
