Operation & Maintenance Manual

General Information

Lubrication is an essential part of preventive maintenance, affecting to a great extent the
useful life of the compressor. Different lubricants are needed and some components 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 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. The intervals are based on normal operating conditions. In the event of
extreme (hot, cold, dusty, or wet) operating conditions, more frequent lubrication may be
necessary.
All filters and filter elements for air and compressor oil must be obtained through Portable
Power to ensure the proper size and filtration for the compressor.

Compressor Oil Change

The compressor is normally furnished with an initial supply of oil sufficient to allow operation
until the first service interval indicated in the Maintenance Schedule. If a compressor has been
completely drained of all oil, it must be refilled with new oil before it is placed in operation.
Refer to specifications in the Portable Compressor Oil Chart in this section.
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 compressor has been operated for the time/hours indicated in the Maintenance
Schedule, it should be completely drained of oil. If the compressor has been operated under
adverse conditions, or after long periods in storage, an earlier change may be necessary as
oil deteriorates with time as well as by operating conditions.
In severe applications, such as, sandblasting, quarry drilling, well
drilling, and oil and gas drilling, more frequent service intervals will be
required to ensure long component life.
