Operation & Maintenance Manual
Compressor Oil Cooler
The compressor lubricating and cooling oil is cooled by means of the fin and tube type
oil cooler, located beside the radiator. The lubricating and cooling oil, flowing internally
through the core section, is cooled by the air stream from the cooling fan flowing past the
core section. When grease, oil, and dirt accumulate on the exterior surfaces of the oil cooler,
its efficiency is impaired.
Each month it is recommended that the oil cooler be cleaned by directing compressed air
which contains a nonflammable, non-caustic safety solvent through the core of the oil cooler.
This should remove the accumulation of grease, oil, and dirt from the exterior surfaces of
the oil cooler core so that the entire cooling area can transmit the heat of the lubricating and
cooling oil to air stream.
In the event foreign deposits, such as sludge and lacquer, accumulate in the oil cooler to
the extent that its cooling efficiency is impaired, a resulting high discharge air temperature is
likely to occur, causing shut down of the unit. To correct this situation it will be necessary
to clean the cooler using a cleaning compound in accordance with the manufacturer’s
recommendations.
Compressor Oil
The lubricating and cooling oil must be replaced every 500 hours of operation or six (6)
months, whichever comes first. Refer to warranty section about extended warranty.
Receiver Separator System
High pressure air can cause severe injury or death from hot oil and flying
parts. Always relieve pressure before removing caps, plugs, covers, or
other parts from pressurized air system.
•
Open service valve at end of machine.
•
Ensure pressure is relieved, with BOTH:
•
Discharge air pressure gauge reads zero (0).
No air discharging from service valve.
Remove plug near bottom of separator tank to drain compressor oil.
When adding oil, remove and replace (make tight) plug on top of separator tank.
The life of the oil separator element is dependent upon the operating environment (soot,
dust, etc.) and should be replaced every twelve months or 1000 hours. To replace the
element proceed as follows:
•
Ensure the tank pressure is zero (0).
•
Unscrew separator element from manifold.
•
Lubricate gasket with compressor oil. Install new element.
