Maintenance Operation & Maintenance Manual

Inspection
Examine the filter element. Examine all hoses and tubes, and replace if necessary.
Reassembly
Thoroughly clean the orifice/drop tube and filter gasket contact area before reassembly. Install
the new element.
WARNING
!
Do not remove the staple from the anti–static gasket on the separator
element since it serves to ground any possible static build–up. Do not
use gasket sealant since this will affect electrical conductance.
Reposition the cover plate, taking care not to damage the gasket, and replace the cover plate
screws tightening in a
criss–cross pattern to the recommended torque (refer to the TORQUE
SETTING TABLE later in this section).
Replace the drop–tube and reconnect all hoses and tubes to the separator tank cover plate.
Replace the compressor oil (refer to LUBRICATION later in this section).
CAUTION
!
Start the machine (refer to PRIOR TO STARTING and STARTING THE
UNIT in the OPERATING INSTRUCTIONS section of this manual) and
check for leakage before the machine is put back into service.
Compressor Oil Cooler and Engine Radiator Air Charge Cooler
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.
