COMPRESSOR LUBRICATING OIL
Refer to the SERVICE/MAINTENANCE CHART in this section for
service intervals.
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.
RUNNING GEAR WHEEL BEARINGS
Wheel bearings should be packed with heavy duty wheel bearing
grease every 6 months.
Wheel bearings should be greased per the Maintenance Schedule in
this manual. The type of grease used should conform to specifications
below:
Grease
Thickener Type Lithium Complex
Dropping Point 215°C (419°F) Minimum
Consistency NLGI No.2
Additives EP, Corrosion & Oxidation Inhibitors
Viscosity Index 80 Minimum
NOTE: If the machine has been operating under adverse conditions,
or has suffered long shutdown periods, then more frequent service
intervals will be required.
WARNING: 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).
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.
CAUTION: Some oil mixtures are incompatible and result in the
formation of varnishes, shellacs or lacquers which may be insoluble.
