Note
Dirty operating conditions, especially lubrication
oil and fuel deposits on the cooling fins of the cyl-
inder and in the cooling air intake reduce the cool-
ing power. You should therefore immediately seal
any leaks in the area of the fuel tank, the cylinder
or the cooling air intake and clean the cooling fins
after.
!
Caution
For cleaning the engine must be stopped and
cooled down.
