8. Operation

CUTTING WORK (LINE 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 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 cut-

ting. 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

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 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 cutter 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 advances

about 25 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.
