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 INGERSOLL-RAND Pro-Tec
