Operating & Maintenance Manual
Lubrication
General Information
Lubrication is an essential part of preventive maintenance, affecting to a great extent the
useful life of the unit. Different lubricants are needed and some components in the unit require
more frequent lubrication than others. Therefore, it is important that the instructions regarding
types of lubricants and the frequency of their application be explicitly followed. Periodic
lubrication of the moving parts reduces to a minimum the possibility of mechanical failures.
The Preventive Maintenance Schedule shows those items requiring regular service and the
interval in which they should be performed. A regular service program should be developed to
include all items and fluids. These intervals are based on average operating conditions. In the
event of extremely severe (hot, cold, dusty or wet) operating conditions, more frequent
lubrication than specified may be necessary. Details concerning lubrication of the running gear
are in Maintenance Section.
All filters and filter elements for air and compressor lubricant must be obtained through
Ingersoll-Rand to assure the proper size and filtration for the compressor.
Compressor Oil Change
These units are normally furnished with an initial supply of oil sufficient to allow operation of
the unit for approximately 6 months or 1000 hours, whichever comes first. If a unit has been
completely drained of all oil, it must be refilled with new oil before it is placed in operation.
Refer to specifications in Lubrication Table.
Some oil types are incompatible when mixed and result in the formation
of varnishes, shellacs, or lacquers which may be insoluble. Such
deposits can cause serious troubles including clogging of the filters.
Where possible, do NOT mix oils of different types and avoid mixing
different brands. A type or brand change is best made at the time of a
complete oil drain and refill.
If the unit has been operated for the time/hours mentioned above, it should be completely
drained of oil. If the unit has been operated under adverse conditions, or after long periods in
storage, an earlier change period may be necessary as oil deteriorates with time as well as by
operating conditions.
