air intake openings
Note
L
Dirty operating conditions, particularly lubrication
oil and fuel deposits on the cooling fins of the en-
gine and the cooling air intake opening have an
adverse effect on the cooling of he engine. You
should therefore immediately seal any oil or fuel
leaks near cooling fan, cylinder or cooling air in-
take and subsequently clean the cooling fins.
Fig. 31
Brush off dried on dirt from all cooling fins and
cooling openings and blow the dirt off with
compressed air (Fig. 31).
Clean an oily dirt with a cold cleansing agent.
Caution
Ä
Do not guide the water jet directly into air filter/
carburettor, starter/air intake and ignition
switch.
After a sufficient soaking time clean off with a
water or steam jet and blow out with com-
pressed air.
Run the engine warm for a while to avoid cor-
rosion.
