Compressor Oil Filter
Refer to the MAINTENANCE CHART in this section for the recommended servicing intervals.
Removal
Do not remove the filter(s) without first making sure that the machine is
stopped and the system has been completely relieved of all air pressure.
(Refer to STOPPING THE UNIT in the OPERATING INSTRUCTIONS section
of this manual).
Clean the exterior of the filter housing and remove the spin-on element by turning it in a
counter-clockwise direction.
Inspection
Examine the filter element.
If there is any indication of the formation of varnishes, shellacs or
lacquers on the filter element, it is a warning that the compressor
lubricating and cooling oil has deteriorated and that it should be changed
immediately. Refer to LUBRICATION later in this section.
Reassembly
Clean the filter gasket contact area and install the new element by screwing in a clockwise
direction until the gasket makes contact with the filter housing. Tighten a further ½ to ¾ of a
revolution.
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.
