Operation - Campbell Hausfeld Air compressor Operating Instructions Manual

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/nil removal equipment
and controls as necessary for the
intended application.
Failure to install
I NOTICE I app.pria
waterloil removal equipment may result
in damage to machinery or workpiece.
GUARDING
The belt 9uard 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 to the
center of _m sight gauge or maximum
mark on dipsttck (see Figure 5).
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. Fillpump with single-viscosi-
ty, ISO100, non_etergent, compressor
oil. Recommended ST126700AV com-
pressoroil 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 causeoil to leak
and sprayout during operation. Fill to
the center of the sight gauge or max-
imum mark on dipstick (see Figure
5).
Using any other
I_CAUTIONI type ofoilmy
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

ready for use.

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

IMPORTANT: Change oil after first 50

NOTE; Thiscompressorhasa maximum
operating pressureof 175 psifor two-
stage compressors or 135 psi for single
stage compressors. D o not alter pressure
settingson control componentsabove 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).
