COOLING SYSTEM

Tokeep the working t emperatureas low as
possible the machine is equipped with a
cooling system.
The cooling system consists of:
SAir intake on the starter
SAir guide plate
SFins on the flywheel
SCooling fins on the cylinder
SCylinder 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.
