Holding the lawn trimmer
Before using the unit, place
yourself in the operating position
(Fig. 12). Check the following:
– The user is wearing eye protec-
tion and the correct clothing.
– The shoulder strap has been
set to the correct height.
– The handle bar has been set
in such a way that you can grip
it with both hands without having
to stretch out your arms.
– The unit is below waist height.
– Hold the cutting attachment
parallel to the ground so that
the vegetation to be cut can
easily be reached without the
user having to bend forward.
Setting the length
of the trimmer line
(depending on model)
You can release the trim line with
the bump knob cutting attachment
without stopping the engine.
To release more line, tap the
cutting attachment on the ground
(Fig. 13) while running the lawn
trimmer at a higher speed.
Note
The trim line should always
be at max. length.
The shorter the trim line becomes,
the more difficult it is to release.
Each time the head is bumped,
.
approx. 25 mm of cutting line are
released. A blade in the cutting
attachment cover cuts the line back
to the correct length if too much line
is released.
