MAINTENANCE
Cooling system
To maintain as low operating
temperature as possible the
engine is equipped with a
cooling system.
The cooling system consists
of:
1. An air intake on the
starter unit.
2. Cooling fins on the
flywheel.
3. Cooling fins on the
cylinder
4. Cylinder cover (leads
cold air onto the
cylinder).
Clean the cooling system
using a brush at least once a
week, in difficult conditions
more often.
A dirty or blocked cooling
system leads to the engine
overheating resulting in
damage to the cylinder and
piston.
Muffler
NOTE!
Some mufflers are fitted with
a catalytic converter. See
“Technical data” to see
whether you clearing saw is
fitted with a catalytic
converter.
The muffler is designed to
dampen the noise level and to
direct the exhaust fumes away
from the user. The exhaust
fumes are hot and can
contain sparks, which can
result in fire if the exhaust
fumes are directed towards a
dry and inflammable mate-
rial. Some mufflers are
equipped with a special spark
arrest screen. If your machine
is fitted with this type of
screen it should be cleaned
regularly. This is done using a
wire brush. On mufflers
without a catalytic converter
the screen should be cleaned
weekly, or replaced if
necessary. On mufflers fitted
with a catalytic converter the
screen should be checked and
cleaned monthly. If the
screen is damaged it should
be replaced. If the screen is
frequently blocked, this can
be a sign that the function of
the catalytic converter is
impaired. Contact your dealer
to inspect the muffler. A
blocked screen will cause the
engine to overheat resulting
in damage to the cylinder and
piston. Also see under
“Maintenance”.
NOTE!
Never use a machine with a
defective muffler.
!
WARNING!
Mufflers fitted with catalytic converters
become extremely hot during use and
after stopping. This also applies at idling
speeds. Contact can result in burns to
the skin. Be observant to the risk of fire!
