Description
The Campbell Hausfeld portable
contractor air compressor is intended for
use in construction and workshop
conditions. An oil lubricated, electric
motor driven compressor provides
compressed air to power nailers, staplers,
paint guns and other air tools. The
compressed air produced by the unit will
contain traces of oil and water. In-line
filters may be required for some
applications.
A pressure switch shuts off the
compressor when the tank is filled to 125
PSI. When air is used and the tank
pressure drops to 100 PSI, the compressor
will restart automatically. The regulator
may be set to provide a line pressure
lower than the tank pressure.
The valve on the compressor outlet
fitting vents air for ease in motor startup.
The sound of vented
air is especially
noticeable when the tank pressure is low
and is not a defect.
The pressure switch also has an unloader
valve to vent air when the compressor
stops.

Preparation
LUBRICATION
THIS UNIT
CONTAINS NO OIL!
Fill the crankcase to the full line on the
dipstick before turning unit on. Crankcase
requires 7.1 fluid oz. (210 ml) of oil to fill.
Operating without oil, even for just a few
seconds will damage the pump.
Use Chevron synthetic 5W-30, Mobil 1
5W-30 or 0W-30 synthetic motor oil in this
compressor. Using other types of oil will
cause starting problems.
1. Check and tighten all bolts, fittings,
etc., before operating compressor.
2. Operate compressor in a ventilated
area so that compressor may be
properly cooled.
3. Locate compressor on a level surface
where it can be directly plugged
NOTICE
into an outlet. If accidentally
bumped, ensure compressor will
not fall on anyone or anything.
4. If extension cord is used, refer to
chart on page 3 to select the
appropriate cord.
5. To avoid loss of power and
overheating, use additional air hose
instead of extension cords to reach
work area.
WIRING
Local electrical wiring codes differ from
area to area. Source wiring, plug and
protector must be rated for at least the
amperage and voltage indicated on
motor nameplate and meet all
electrical codes for this minimum.
NOTE: This compressor unit may be

MOISTURE IN COMPRESSED AIR
Moisture in compressed air will form
into droplets as it comes from an air
compressor pump. When humidity is
high or when a compressor is in
continuous use for an extended
period of time, this moisture will
collect in the tank. When using a
paint spray or sandblast gun, this
water will be carried from the tank
through the hose, and out of the gun
as droplets mixed with the spray
material.
IMPORTANT: This condensation will
cause water spots in a paint job,
especially when spraying other than
water based paints. If sandblasting, it
will cause the sand to cake and clog
the gun, rendering it ineffective.
A filter in the air line, located as near
to the gun as possible, will help
eliminate this moisture.
