9.7.
COMPRESSOR OIL COOLER AND
ENGINE RADIATOR
When grease, oil and dirt accumulate on the exterior surfaces of
the oil cooler and radiator, the efficiency is impaired. It is
recommended that each month the oil cooler and radiator be
cleaned by directing a jet of compressed air, (carrying if possible
a non---flammable cleaning solvent) over the exterior core of the
cooler/radiator. This should remove any accumulation of oil,
grease and dirt from the exterior core of the cooler so that the
entire cooling area can radiate the heat of the lubricating and
cooling oil/water into the air stream.
WARNING
HOT ENGINE COOLANT AND STEAM CAN CAUSE
INJURY. WHEN ADDING COOLANT OR ANTIFREEZE
SOLUTION TO THE ENGINE RADIATOR, STOP THE
ENGINE AT LEAST ONE MINUTE PRIOR TO RELEASING
THE RADIATOR FILLER CAP. USING A CLOTH TO
PROTECT THE HAND, SLOWLY RELEASE THE FILLER
CAP, ABSORBING ANY RELEASED FLUID WITH THE
CLOTH. DO NOT REMOVE THE FILLER CAP UNTIL ALL
EXCESS FLUID IS RELEASED AND THE ENGINE
COOLING SYSTEM FULLY DEPRESSURISED.
