Campbell Hausfeld Oil-Lubricated Compressor HL5403 - Manual (Page 3)

Pressure switch - Auto/Off Switch - In
the aUtO position, the compressor
shuts off automatically when tank
pressure reaches the maximum preset
pressure. 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 or when
changing air tools.
Regulator - The regulator controls
the amount of air pressure at the
hose outlet. Turning regulator knob
clockwise (to the right) will increase air
pressure at the outlet. Turning knob
counterclockwise (to the left) will lower
air pressure to the outlet. Turning knob
fully counterclockwise will shut off flow
of air completely.
asMe safety valve - This valve is
attached to the pressure switch. It will
automatically releases air if the tank
pressure exceeds the preset maximum.
exhaust 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 exhaust tube.
Check valve - This valve is located at
the end of the exhaust tube where it
meets the tank. It is a one-way valve
that allows air to enter the tank, but
prevents air in the tank from flowing
back into the compressor pump.
handle - Designed to move the
compressor.
Never use the
handle on wheeled
units to lift the unit completely off the
ground.
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.
Pressure Gauges - These gauges will
show air pressure in the compressor
tank and at the compressor outlet.

Glossary of terms
Outlet Pressure Gauge - Will show
air pressure at the outlet in pounds per
square inch (psi). Make sure this gauge
reads ZERO (by adjusting regulator
knob fully counterclockwise) before
changing air tools or disconnecting air
hose from outlet.
tank Pressure Gauge - Will show air
pressure in tank while the compressor
is running, indicating compressor
is building pressure properly. This
gauge will show maximum pressure
of compressor when it shuts off
automatically at the pressure switch.
Motor Reset - (not shown, located
inside motor). Designed to keep the
motor from overheating. The motor has
an auto reset protector. To reset once
the motor has cooled, turn the pressuer
switch to the OFF position, then to the
AUTO position.
This compressor is
equipped with an
overload protector which will shut off
motor if it becomes overloaded.
If the overload
protector is
actuated, the motor must be allowed
to cool down for approximately 30
minutes before it will reset.
Installation
LOCatIOn
It is extremely important to install the
compressor in a clean, dry, and well
ventilated area. The compressor must
be placed on a firm, level surface where
the surrounding air temperature will
not be more than 100°F.
A minimum clearance of 18 inches
between the compressor and a wall is
required because objects could obstruct
air flow.
Do not locate the
compressor air inlet
near steam, paint spray, sandblast areas
or any other source of contamination.
This debris will damage the motor.
eLeCtRICaL InstaLLatIOn
All wiring and
electrical
connections should be performed by a
qualified electrician. Installation must
be in accordance with local codes and
national electrical codes.
