Operation & Maintenance Manual
Compressor Oil Cooler, Engine Radiator, and other Heat
Exchangers
When grease, oil, and dirt accumulate on the exterior surfaces of the heat exchangers, the
efficiency is impaired. It is recommended the heat exchangers be cleaned per the
Maintenance Schedule in this manual. Directing a jet of compressed air should remove any
accumulation of oil, grease, and dirt from the exterior cores of the cooler so the entire cooling
area can radiate heat into the air stream. Access doors are located on each side of the
compressor to aid in cleaning the heat exchangers.
Hot engine coolant and steam can cause injury. When adding coolant or
antifreeze solution to the engine radiator, stop the engine and allow
radiator to cool prior to releasing the radiator pressure cap. Using a cloth
to protect the hand, slowly release the pressure cap, absorbing any
released fluid with the cloth. Do not remove the pressure cap until all
excess fluid is released and the engine cooling system fully
depressurized.
Follow the instructions and precautions provided by the antifreeze
supplier when adding or draining the antifreeze solution. Wear personal
protective equipment to prevent skin and eye contact with the antifreeze
solution.
Air Filter Elements
The air filter elements should be replaced regularly (refer to the Maintenance Schedule) or
when indicated on the control panel, whichever comes first. The air cleaner precleaner dumps
should be cleaned as indicated in the Maintenance Schedule (more frequently in dusty
operating conditions).
Removal
Never remove and replace element(s) when the compressor is in
operation.
Clean the exterior of the filter housing of dirt and debris and remove the primary filter element
by releasing the retaining wing nut.
If the safety element is to be replaced, thoroughly clean the interior of the filter housing prior
to removing the safety element.
