Features
AUTO (1) / OFF (O) SWITCH
Place this switch (E) in the AUTO (1) position
to provide automatic power to the pressure
switch and OFF (0) to remove power at the
end of each use.
DANGER: Risk of Shock. ALWAYS ensure the switch (E) is in the
OFF (0) position and unit is unplugged before removing or
replacing pressure switch cover.
PRESSURE SWITCH
The pressure switch (not shown) automatically starts the motor
when the tank pressure drops below the factory set cut-in
pressure. It stops the motor when the tank pressure reaches the
factory set cut-out pressure.
SAFETY VALVE
This valve (A) is designed to prevent system
failures by relieving pressure from the system
when the compressed air reaches a predeter-
mined level. The valve is preset by the manu-
facturer and must not be removed or modified
in any way.
CHECK VALVE
When air compressor is operating, the check
valve (B) is open, allowing compressed air to
enter the tank. When the air compressor reach-
es cut-out pressure, the check valve closes,
allowing air pressure to remain inside the tank.

AIR INTAKE FILTER
The filter (C) is designed to clean air entering
the pump. To ensure the pump continually
receives a clean air supply, the filter must
always be clean and the filter intake must be
free from obstructions.
TANK DRAIN VALVE
The drain valve (I) is located at the base of the
tank and is used to drain condensation at the
end of each use. See Draining Tank under
Maintenance.
TANK PRESSURE GAUGE
The tank pressure gauge (G) indicates the
reserve air pressure in the tank.

REGULATOR
(Sold separately, not shown) An air pressure
regulator or a separate air transformer which
combines the functions of air regulation and/
or moisture and dirt removal is recommended
for most applications. See Air Distribution System paragraph
under Installation.

DANGER: Risk of Bursting. Too much air pressure causes a hazardous
risk of bursting. Check the manufacturer's maximum pressure rating for
air tools and accessories. The outlet pressure must never exceed the
maximum pressure rating of the tools or accessories.
