METHOD FOR CHECKING AND CLEANING RADIATOR FINS, OIL COOLER FINS,
AFTERCOOLER FINS, FUEL COOLER FINS, AND AIR CONDITIONER CONDENS-
ER FINS
If the compressed air, high-pressure water, or steam hits your body directly or dirt is scattered by use of
it, there is a danger of personal injury. Wear the protective equipment such as the protective eyeglasses
and dust mask.
NOTICE
When using the compressed air, blow it from some distance to avoid damaging the fins. Especially
when blowing the compressed air against the fuel cooler and aftercooler by 45 ° angle, keep the nozzle
300 mm or more away from them.
Blow it vertically as possible toward the core. Damage on the fins can cause water leakage and over-
heating.
In a dusty job site, check the fins every day, regardless of the maintenance interval.
