MAINTENANCE
Muffler
CAUTION! Some mufflers are fitted with a catalytic
converter. See chapter on Technical data to see whether
your machine is fitted with a catalytic converter.
The muffler is designed to reduce the noise level and to
direct the exhaust gases away from the operator. The
exhaust gases are hot and can contain sparks, which may
cause fire if directed against dry and combustible
material.
CAUTION! Never use a machine with a defective muffler.
Cooling system
To keep the working temperature as low as possible the
machine is equipped with a cooling system.
The cooling system consists of:
1 Cooling fins on the cylinder.
2 Cylinder cover (directs cold air over the cylinder).
3 Air intake through the crankcase (inside the tank).
Clean the cooling system with a brush once a week, more
often in demanding conditions. A dirty or blocked cooling
system results in the machine overheating which causes
damage to the piston and cylinder.
Spark plug
The spark plug condition is influenced by:
•
Incorrect carburettor adjustment.
•
An incorrect fuel mixture (too much or incorrect type
of oil).
•
A dirty air filter.
These factors cause deposits on the spark plug
electrodes, which may result in operating problems and
starting difficulties.
WARNING! Mufflers fitted with catalytic
converters get very hot during use and
remain so for some time after stopping.
This also applies at idle speed. Contact
can result in burns to the skin.
Remember the risk of fire!
!
Before proceeding to adjust or repair
the machine, be sure to stop the engine
and detach the spark plug.
After the engine has stopped, the
muffler is still hot.
