ADJUSTING IDLING SPEED
(1) Idle speed adjuster
1. When the engine tends to stop frequently at idling
mode, turn the idle speed adjuster clockwise.
2. When the cutting head keeps rotating after releasing
the trigger, turn the idle speed adjuster counter-
clockwise.
NOTE
• Warm up the engine before adjusting the idling
speed.
CUTTING WORK (TRIMMER HEAD USAGE)
WARNING
1. Always wear eye protection such as safety gog-
gles. 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 cutting attachment guard 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.
1. Hold the unit so the head is off the ground and is
tilted about 20 degrees toward the sweep direction.
2. You can avoid thrown debris by sweeping from your
left to the right.
3. Use a slow, deliberate action to cut heavy growth.
The rate of cutting motion will depend on the mate-
rial being cut. Heavy growth will require slower action
than will light growth.
4. Never swing the unit so hard as you are in danger of
losing your balance or control of the unit.
5. Try to control the cutting motion with the hip rather
than placing the full workload on the arm and
hands.
6. 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 brush cutters are equipped with a semi- auto
type nylon trimmer 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.
