COOLING SYSTEM
To keep the working temperature as low as
possible the machine is equipped with a
cooling system.
The cooling system consists of:
S Air intake on the starter
S Air guide plate
S Fins on the flywheel
S Cooling fins on the cylinder
S Cylinder cover (directs cold air over the
cylinder)
Clean the cooling system with a brush after
each use, more often in demanding condi-
tions. A dirty or blocked cooling system re-
sults in the machine overheating which
causes damage to the piston and cylinder.

steps after each use:
S Allow the engine to cool, and secure the
