Blow off mud, dirt, leaves, etc. in radiator fins (3), aftercool-
er fins (4), air conditioner condenser fins (5), and oil cooler
fins (6) with compressed air.
NOTICE
Steam or water may be used instead of the com-
pressed air.
However, when using the powerful steam cleaning
equipment (high-pressure machine wash) for the heat
exchange equipment (radiator), keep a sufficient dis-
tance to the target.
If steam cleaning (high-pressure machine wash) is per-
formed at close distance, there is a danger that the in-
ternal fins of the heat exchange equipment may be de-
formed, and this will cause early clogging and break-
age of the equipment.
