If, for any reason, the unit has been drained, it must be re−filled with
new oil before it is put into operation.

recommended intervals. Refer to the Engine section of this manual.
ENGINE LUBRICATING OIL SPECIFICATION
Refer to the Engine section of this manual.
ENGINE OIL FILTER ELEMENT
The engine oil filter element should be changed at the engine
manufacturer’s recommended intervals. Refer to the Engine section of
this manual.
COMPRESSOR LUBRICATING OIL
Refer to the SERVICE/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.
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 UNIT 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.
CAUTION: Some oil mixtures are incompatible and result in the
formation of varnishes, shellacs or lacquers which may be insoluble.
NOTE: Always specify PRO−TEC oil for use at all ambient
temperatures above −23C.
COMPRESSOR OIL FILTER ELEMENT
Refer to the SERVICE / MAINTENANCE CHART in this section for
service intervals.
