Running in the engine
1. During the first ten hours of work, run the engine at a
moderate RPM.
2. We advise you in any case not to maintain your engine at
a high speed as the different components must settle with
each other during the process of running in the engine.
3. It is at the end of the running in period that the engine
will reach its maximum power.
4. After the first two hours of work, stop and make sure
that all nuts and screws are securely fastened, and
tighten them if necessary.
Use of the petrol line trimmer
This petrol line trimmer is only made to cut grass, small
bushes, and shrubs.
• Always use the shoulder strap, when using the tool to
avoid serious personal injury.
• Perform a few accelerations of the motor without
reaching maximum speed and without working to make
sure that everything is in good working order.
• Start the engine only when you are close to the
working area.
• Place yourself in a well balanced position, stable on
both feet.
Grass cutting
Cut the grass like you are in a corridor about 1.5m wide.
Move step by step, moving the machine from left to right
and vice-versa. Make sure at each step that you are still
well balanced on your feet.
The line trimmer has a bump feed mechanism which
releases line without having to stop the engine. To release
additional line lightly tap the cutting line and spool
assembly (1) on the ground while operating the unit at
high speed.
NOTE. Always keep the trimming line fully extended. Line
release becomes more difficult as the cutting line becomes
shorter.
Each time the head is bumped it releases approximately
2cm of line. The cut off knife (2) on the blade guard will
automatically cut off any excess line. For best results tap
the head on hard soil or bare ground.
Do not hit stones (even small ones), piles of earth, and
small pieces of wood or anything else that could be
hidden or poorly visible in the grass. If you hit a large
object by accident, or if you block the cutting tool due to
overloading or having the cutter jammed with grass, you
must stop the engine.
NOTE. All protective devices of the machine as well
as protective equipment must be maintained in good
operation condition during the period of use.
WARNING. The engine of the petrol line trimmer must be
at a complete stop during assembling, repair and cleaning
operations that could be necessary.
Petrol line trimmer 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.
Maintenance
Air filter
Accumulated dust in the air filter will reduce engine
efficiency. Increase fuel consumption and allow abrasive
particles to pass into the engine. Remove the air filter as
often as necessary to maintain a clean condition.
• Remove filter cover (12) by
pressing in the sides and
lifting it off.
• Light surface dust can readily
be removed by tapping
the filter.
• Heavy deposits should be
washed out in suitable
detergent.
