SAFETY INSTRUCTIONS
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 tight-
ened.
The edges of the blade are
too hard to be filed. Dull
blades should be sharp-
ened using a grinder.
7. Blade guard
• Replace the blades if they
are bent or damaged.
