COMPRESSOR LUBRICATING OIL
Refer to the MAINTENANCE CHART in this section for service intervals.
NOTE: If the machine has been operating under adverse conditions, or
has suffered long shutdown periods, then more frequent service intervals
will be required.
DO NOT, under any circumstances, remove any drain plugs or the oil
filler-plug from the compressor lubricating and cooling system without
first making sure that the machine is stopped and the system has been
completely relieved of all air pressure (refer to STOPPING THE MACHINE
in the OPERATING INSTRUCTIONS section of this manual).
Completely drain the receiver/separator system including the piping and
oil cooler by removing the drain plug(s) and collecting the used oil in a
suitable container.
Replace the drain plug(s) ensuring that each one is secure.
NOTE: If the oil is drained immediately after the machine has been
running, then most of the sediment will be in suspension and will
therefore drain more readily.
Some oil mixtures are incompatible and result in the formation of
varnishes, shellacs or lacquers which may be insoluble. Refer to Portable
Compressor Fluid Chart.
RUNNING GEAR WHEEL BEARINGS
Wheel bearings should be packed with grease every 12 months. The type of grease used
should conform to specification MIL-G-10924.
