RUNNING IN THE ENGINE
A factory-new machine should run at moderate speed for the first 2-3 hours of
work, as different components need to settle with each other during the process of
running in the engine.
The engine can reach its maximum power after this running in period.
After the first 2-3 hours of works, stop and make sure that all nuts and screws are
securely fastened, and tighten them if necessary.
WARNING!
Never direct the line trimmer discharge stream toward people or
animals. Always be aware of the strength and direction of stream.
NOTE:
Petrol line trimmers transmit vibrations to the operator during use. These
vibrations can generate increased fatigue. For this reason, we recommend taking
regular breaks during work. We also recommend taking a break after a few hours of
work to rest the engine. If abnormal noise or vibration occurs during operation, turn
the line trimmer off immediately and have the problem corrected.
1. Keep a firm grip on the trimmer with both hands while in operation. The
trimmer should be held at a comfortable position with the rear handle about
hip height.
2. Always operate the trimmer at an appropriate throttle level. Cut tall grass from
the top down to prevent grass from wrapping around the spool which may
cause the trimmer to overheat.
NOTE.
If grass becomes wrapped around the spool, stop the engine, disconnect
the spark plug wire, and remove the grass.
NOTE.
Prolonged cutting not at full throttle may result in oil dripping from the
muffler.
WARNING!
The engine of the petrol line trimmer must be at a complete stop
during assembling, repair and cleaning operations that could be necessary.
FEEDING THE LINE
The line trimmer has a bump feed mechanism which releases the line without
having to stop the engine.
To release additional line, lightly tap the cutting line and spool assembly on the
ground while operating the unit at high speed.
NOTE. Always keep the line fully extended. Line release becomes more difficult
as the cutting line becomes shorter. Each time the head is bumped it releases
