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 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.
