Operation

IMPORTANT: Check motor rotation
before operating the compressor.
All lubricated compressor pumps dis-
charge some condensed water and oil
with the compressed air. Install appro-
priate water/oil removal equipment
and controls as necessary for the
intended application.
Failure to install
NOTICE
!
appropriate
water/oil removal equipment may result
in damage to machinery or workpiece.

GUARDING

The belt guard provided
must be installed before
operating the unit.
All moving parts must be guarded. All
electrical covers must be installed
before turning on the power.
LUBRICATION
THIS UNIT CON-
TAINS NO OIL.
Before operating compressor, fill
crankcase with compressor oil accord-
ing to the oil capacity chart listed in
"Replacement Parts Manual."
Some residual oil may still be in the pump
leaving a thin coat on the sight glass,
however; there is not enough oil to oper-
ate the unit. Fill pump with single-viscosi-
ty, ISO100, non-detergent, compressor
oil. Use part number ST126700AV, one
gallon of compressor oil or Mobil 1
5W30 or 10W30 synthetic oil may also be
used. Add oil only through the oil fill
plug. Pouring oil into any other orifice
will cause oil to leak and spray out during
operation. Fill to the center of the sight
gauge or maximum mark on dipstick (see
Figure 5).
Using any other
type of oil may
shorten pump life and damage valves.

RECOMMENDED BREAK-IN PERIOD

The compressor should be run continu-
ously for one hour to allow proper
seating of the piston rings.
1. Open drain cock completely and run
the compressor for 60 minutes (See
Figure 6).

2. Turn off the compressor and close
drain cock. The compressor is now
ready for use.

If the compressor is run under humid
conditions for short periods of time, the
humidity will condense in the crankcase
and cause the oil to look creamy. Oil
contaminated by condensed water will
not provide adequate lubrication and
must be changed immediately. Using
contaminated oil will damage bearings,
pistons, cylinders and rings and is not
covered under warranty. To avoid water
condensation in the oil, periodically run
the compressor with tank pressure near

150 psi for two-stage compressors or 120
psi for single stage compressors by open-
ing the drain cock or an air valve con-
nected to the tank or hose. Run the
pump for an hour at a time at least once
a week or more often if the condensa-
tion reoccurs.
IMPORTANT: Change oil after first 50
hours of operation.
PRESSURE SWITCH, START - STOP
NOTE: This compressor has a maximum
operating pressure of 175 PSI for two-
stage compressors or 135 PSI for single
stage compressors. Do not alter pressure
settings on control components above
this limit.
The compressor unit starts and stops
based on preset pressure switch set-
tings. The pressure switch contains an
unloader which is a small valve that
vents air to allow the motor to start
easily (See Figure 7).
