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.
NOTE:
Warm up the engine before adjusting the
idling speed.
Trimmer Head Usage:
WARNING
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.
1. Hold the unit so the head is off the
ground and is tilted about 20 degrees
toward the sweep direction. (OP6)
2. You can avoid thrown debris by sweeping from your right to the left.
3. 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.
4. Never swing the unit as 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.

in turn may cause mechanical failure on the part of
the brush cutter
