4.15 Cleaning cooling fins and
cooling air intake opening
Note
L
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.
Dry dirt

Dry clean the entire cooling air area like cylin-
der head, cylinder flywheel blower and blow it
out with compressed air (Fig. 37).
Wet or oily dirt
Danger
