■ STOPPING ENGINE
1. Release the throttle lever and run the
engine for a half minute.
2. Shift the ignition switch to the STOP
position.
• Except for an emergency, avoid stopping
the engine while pulling the throttle lever.
■ ADJUSTING IDLING SPEED
1. When the engine tends stop frequently at
idling mode, turn the adjusting screw
clockwise.
2. When the cutting head keeps rotating after
releasing the trigger, turn the adjusting
screw counter-clockwise.
• Warm up the engine before adjusting the
idling speed.
■ LINE HEAD USAGE
1. Always wear eye protection such as
safety goggles. Never lean over the
rotating cutting head. Rocks or other
debris could be thrown into eyes and
face and cause serious personal injury.
2. Keep the debris guard attached in
place at all times when the unit is
operated.
TRIMMING GRASS AND WEEDS
• Always remember that the TIP of the line
does cutting. You will achieve better results
by not crowding the line into the cutting
area. Allow the unit to trim at its own pace.
WARNING
NOTE
NOTE
1. Hold the unit so the head is off the ground
and is tilted about 20 degrees toward the
sweep direction.
2. Use full throttle when cutting.
3. You can avoid thrown debris by sweeping
from your left to the right.
4. Use a slow, deliberate action to cut heavy
growth. The rate of cutting motion will
depend on the material being cut. Heavy
growth will require slower action than will
light growth.
5. Never swing the unit so hard as you are in
danger of losing your balance or control of
the unit.
6. Try to control the cutting motion with the
hip rather than placing the full workload on
the arm and hands.
7. Take precautions to avoid wire, grass and
dead, dry, long-stem weeds from wrapping
around the head shaft. Such materials can
stall the head and cause the clutch to slip,
resulting in damage to the clutch system if
repeated frequently.
ADJUSTING THE LINE LENGTH
• Your brushcutters is equipped with a semi-
auto type nylon line head that allows the
operator to advance the line without
stopping the engine. When the line
becomes short, lightly tap the head on the
ground while running the engine at full
throttle.
• Each time the head is bumped, the line
advance about 1 inch(25.4 mm). For better
effect, tap the head on bear ground or hard
soil. Avoid bumping in thick, tall grass as
the engine may stall by overload.
