Campbell Hausfeld Portable Air Compressor Operating Instructions Manual page 3

Introduction
R efer to Figures 1a or 1b to locate the
following items.
Pressure switch - Auto/Off Switch - In
the "auto" position, the compressor
shuts off automatically when tank
pressure reaches the maximum preset
pressure. After air is used from the tank
and drops to a preset low level, the
pressure switch automatically turns the
motor back on. In the "off" position,
the compressor will not operate. This
switch should be in the "off" position
when connecting or disconnecting the
power cord from the electrical outlet.
When the pressure switch turns the
motor off you will hear air leaking out
of the pressure switch unloader valve
for a short time. This releases the air
pressure from the discharge tube and
allows the compressor to restart easier.
For units without a manual switch,
whenever the procedures call for
turning the switch to the OFF position,
use the switch at the disconnect instead.
Regulator - The regulator controls the
amount of air pressure released at the
hose outlet (Sold separately).

ASME Safety Valve - This valve
automatically releases air if the tank
pressure exceeds the preset maximum.
Discharge tube - This tube carries
compressed air from the pump to the
check valve. This tube becomes very hot
during use. To avoid the risk of severe
burns, never touch the discharge tube.

Check valve - One-way valve that
allows air to enter the tank, but
prevents air in the tank from flowing
back into the compressor pump.

Tank Drain Valve - This valve is located
on the bottom of the tank. Use this
valve to drain moisture from the tank
daily to reduce the risk of corrosion.
Reduce tank pressure below 10 psi,
then drain moisture from tank daily to
avoid tank corrosion. Drain moisture
from tank(s) by opening the drain valve
located underneath the tank.
T ank Pressure Gauge - Indicates
amount of air pressure stored in tank.
Hose Pressure Gauge - Indicates
amount of air pressure in hose used to
operate tools. This pressure is increased
or decreased by the regulator.
