NOTICE
Procedure
Flushing in a test tank
Before starting the engine, make sure to
supply water to the cooling water passag-
es. Otherwise, the engine could overheat
and be damaged.
Cooling system flushing is essential to pre-
vent the cooling system from clogging up
with salt, sand, or dirt. In addition, fogging/lu-
bricating of the engine is mandatory to pre-
vent excessive engine damage due to rust.
Perform the flushing and fogging at the same
time.

plate, or if the water supply is insuffi-
cient, engine seizure may occur.

Run the engine at a fast idle for a few
minutes in neutral position.
WARNING!
Do not touch or remove electrical
parts when starting or during opera-

Just prior to turning off the engine, quick-
ly spray “Fogging Oil” into the carbure-

engine at a fast idle until the fuel system
empties and the engine stops.
