WARNING!
The cutting blades may move (oscil-
late) when the engine is started. Keep
away from the cutter assembly while
starting the engine!
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).
2. 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 (Figure 13) and fully
depress the throttle lever with your left
hand, then pull the starter handle rap-
idly 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.

Starting the Engine
5. While holding the outer tube firmly
with left hand. Use your other hand
to slowly pull the recoil starter handle
until resistance is felt, then pull quickly
to start the engine.
3. Press the primer bulb until fuel can be
seen flowing in the transparent return
tube.
Make sure the
cutting attach-
ment
is clear of
obstructions!
IMPORTANT!
Engine ignition is controled by a two
position switch mounted on the throttle
housing labeled, "I" for ON or START and
"O" for OFF or STOP.

IMPORTANT!
The primer system only pushes fuel
through the carburetor. Repeatedly
pressing the primer bulb will not ood 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.
ON
1. Slide the ignition switch to the “ON”
position. See Figure 9.
2. Set the throttle lever to the “fast idle”;
a. Squeeze the throttle lever toward the
handgrip on the shaft tube.
b. Depress and hold the throttle lock
button.
c. While depressing the throttle lock
button, release the throttle lever.
Then release the throttle lock button.
See Figure 9.

4. Set the choke
lever to the
CLOSED posi-
tion if engine is
cold.
Never start the engine from the oper-
ating position.
When the Engine Starts...
n After the engine starts, allow the engine
to warm up at idle 2 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 oscillating. 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 ooded
with fuel. If ooding 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.
6. When the engine starts, slowly move
the choke lever to the "OPEN" position.
See Figure 13. (If the engine stops
after the initial start, close the choke
and restart.)
