6. OPERATION

LINE HEAD USAGE

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.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 brushcutter 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.
