Description
Air compressor units are intended to
provide compressed air to power pneumatic tools, operate sprayguns and supply air for pneumatic valves and actuators. The pumps supplied with these
units have oil lubricated bearings. A
small amount of oil carryover ispresent
in the compressed air stream.
Applications requiring air free of oil
vapor should have the appropriate filter
installed. The air compressorunits are to
be mounted per the instructionsprovided on a solid floor. Any other use of
these units will void the warranty and
the manufacturer will not be responsible for problems or damages resulting
from such misuse.Refer to the enclosed
"Replacement Parts Manual" to identify
compressor as single stage or two-stage.

Unpacking
After unpacking the unit, inspect carefully for any damage that may have
occurred during transit. Make sure to
tighten fittings, bolts, etc., before
putting unit into service.
I WARNINGI
This compressor/pump is NOT
equipped and should NOT be used
"as is" to supply breathing quality
air. For any application of air for
human consumption, you must fit
the air compressor/pump with suitable in-line safety and alarm equipment. This additional equipment is
necessary to properly filter and purify the air to meet minimal specifications for Grade D breathing as
