5. Muffler
• Never use a machine that
has a defective muffler.
• Check regularly that the
muffler is secure.
• If your muffler is fitted
with a spark arrest screen
then it should be cleaned
regularly. A blocked
screen leads to the engine
overheating with serious
damage as a result. Never
use a muffler with a
defective spark arrest
screen.
6. Blades
To ensure good cutting
results it is important that
the contact pressure
between the blades is
correct.
The contact pressure
between the blades is
adjusted by tightening the
screws on the underside of
the bar as far as they will go,
then backing them off 1/4
turn. Lock the screws using
the locking nuts on the top
face of the bar. The washers
should still slide freely
under the screw heads after
the screws have been
tightened.
When the blades are
correctly adjusted the play
between the blades should
be 0.2–0.4 mm, measured
at the screws.
The edges of the blade are
too hard to be filed. Dull
blades should be sharpened
using a grinder.
Replace the blades if they
are bent or damaged.

8. Gearbox
• The gearbox gets hot
when the hedge trimmer

touch the gearbox.
