IMPORTANT!
The primer system only pushes fuel through
the carburetor. Repeatedly pressing the
primer bulb will not flood the engine with fuel.
CAUTION!
Do not pull the recoil starter to the end
of the rope travel. Pulling the recoil
starter to the end of the rope travel can
damage the starter.

5. When the engine starts, move the
choke lever to the OPEN position. Clear
excess fuel from the combustion chamber
by revving the engine several times with
the throttle trigger.
If The Engine Fails To Start
Repeat the appropriate cranking procedure
If the engine does not continue to run,
repeat the appropriate cranking procedure
(warm or cold engine).

IMPORTANT!
If the engine fails to start after several
attempts with the choke in the closed
position, the engine may be flooded
with fuel. If flooding is suspected,
move the choke lever to the open position
and repeatedly pull the recoil starter to
remove excess fuel and start the engine.
If the engine still fails to start, refer to the
troubleshooting section of this manual.
Starting A Flooded Engine
1. Disconnect the spark plug lead and use
the spark plug wrench to remove the
spark plug (turn counter clockwise to
remove).
When the Engine Starts...
n
After the engine starts, allow the engine
to warm up at idle or 3 minutes before
operating the unit.
n
Advancing the throttle makes the cut-
ting attachment
oscillate
faster; releas-
ing the throttle permits the attachment
to stop
oscillat
ing. If the cutting attach-
ment continues to
oscillate
when the
engine returns to idle, carburetor idle
speed should be adjusted (see "Adjust-
ing Engine Idle" on the next page).
IMPORTANT!
If the engine fails to start after several
attempts with the choke in the closed
position, the engine may be flooded
with fuel. If flooding is suspected,
move the choke lever to the open position
and repeatedly pull the recoil starter to
remove excess fuel and start the engine.
If the engine still fails to start, refer to the
troubleshooting section of this manual.
. Slide the ignition switch to the “O”
(STOP) position.
If the spark plug is fouled or soaked with
fuel, clean the plug as necessary.
3. Open the choke and fully depress the
throttle lever with your left hand, then
pull the starter handle rapidly with your
right hand to clear excess fuel from the
combustion chamber.
4. Reinstall the spark plug and tighten it
firmly. If a torque wrench is available,
torque the spark plug to 148–165 in.-lb
(170–190 kg/cm).
5. Repeat the starting procedure for a
warm engine.
6. If the engine still fails to start, refer to
the troubleshooting section near the
end of this manual.
