IMPORTANT: This enriched valve only when
the engine is cold at the start, hot-start is not
required for this operation.
4. Your unit is de-
signed with a 3 posi-
tion choke: CLOSED
' ', PARTIAL ' '
y OPEN ' '. Move
choke lever to CLOSED
position.
5. Grip handle firmly;
depress safety trigger & throttle trigger to
FULL THROTTLE position.
6. Pull the recoil starter grip slowly to engage
the starter (at approximately 10 cm), then
give a short, quick pull. A smooth rapid pull is
required for a strong spark. Pull starter rope
briskly 4 times.
7. Once engine starts, allow to run idle for ten
seconds.
8. Move the choke to OPEN position.
NOTE: lf engine fails to start after repeated at-
tempts, refer to 'troubleshooting' section.
NOTE: Always pull starter rope straight out.
Pulling starter at an angle will cause rope to
rub against the eyelet. This friction will cause
the rope to fray and wear more quickly. Always
hold starter handle when rope retracts. Never
allow rope to snap back from extended posi-
tion. This could cause rope to snag or fray and
also damage the starter assembly.
WARM ENGINE START
1. Place trimmer on firm flat surface.
2. Move ignition switch to the "RUN (l)" position.
3. Grip handle firmly, squeeze throttle trigger
to FULL THROTTLE position.
4. Pull starter rope briskly until engine starts,
but no more than 6 times.
5. If engine does not start, please operate
"STARTING A COLD ENGINE" again.
TO STOP ENGINE
Release throttle trigger. Let engine return to
idle. Push and hold ignition stop switch until
engine stops.
OPERATING THE TRIMMER
SAFETY HARNESS
1. Attach the headgear clip on the handle of
the shaft.
E N G L I S H •
2. Adjust the harness to place it in a comfort-
able position.
WARNING: Always place the motor head to
your right side. If you place the trimmer motor
on your left side, you will be exposed to the
motor heat and muffler outlet, this can cause
posible serious injury.
Hold the trimmer with the right hand on the
rear handle and the left hand on the front "D"
handle. Keep a firm grip with both hands while
in operation. Trimmer should be held at a com-
fortable position with the rear handle about
hip height.
Always operate trim-
mer at full throttle.
Cut tall grass from the
top down. This will
prevent grass from
wrapping around
the driveshaft hous-
ing and string head
which may cause dam-
age from overheat-
ing. If grass becomes
wrapped around the
string head, stop the engine, disconnect the
spark plug wire, and remove the grass. Pro-
longed cutting at partial throttle will result in
oil dripping from the muffler.
ADVANCING THE STRING
String advance is con-
trolled by tapping
string head on grass
while running engine
at full throttle.
1. Run engine at full
throttle.
2. Tap string head on ground to advance string.
String advances each time the head is tapped.
3. Several taps may be required until string
strikes the cut off blade.
4. Resume trimming.
NOTE: If the string is worn too short you may
not be able to advance the string by tapping
it on the ground. If so, STOP THE ENGINE, and
manually advance the string.
CUTTING TIPS
• Keep the trimmer tilted toward the area be-
ing cut; the section closest to the ground is the
best cutting area.
