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 Air intake on the starter.
2 Air guide plate.
3 Fins on the flywheel.
4 Cooling fins on the cylinder.
5 Cylinder cover (directs cold air over the cylinder).
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.
Winter use
Running problems can occur when using the machine in
the cold and snowy conditions caused by:
• Too low engine temperature.
• Icing of the air filter and carburettor.
Special measures are therefore often required:
• Partly mask the air inlet on the starter to increase the
working temperature of the engine.
• Preheat the intake air to the carburettor by using the
heat from the cylinder.
Temperature 0°°
°°
C or colder:
Twist the cover so that preheated air from the cylinder can
enter the carburettor space to prevent icing of the air filter,
etc., then fit the rubber seal to the fuel pipe by the main air
intake.

IMPORTANT! If the temperature rises above -5°C or
0
°C respectively the machine MUST be restored to its
normal set-up. Otherwise there is a risk of overheating,
which can cause severe engine damage.
IMPORTANT! Any maintenance other than that
described in this manual must be carried out by your
servicing dealer (retailer).
