Know Your Air Compressor
READ THIS OWNER'S MANUAL AND SAFETY RULES BEFORE
OPERATING YOUR UNIT. Compare the illustrations with your
unit to familiarize yourself with the location of various controls
and adjustments. Save this manual for future reference.
FEATURES
AUTO (-) / OFF (O) SWITCH
Place this switch (B) in the "Auto (-)" position to
provide automatic power to the pressure switch
and "Off (O)" to remove power at the end of each
use.
PRESSURE SWITCH
The pressure switch (not shown) automatically starts the motor when
the air tank pressure drops below the factory set cut-in pressure.
It stops the motor when the air tank pressure reaches the factory set
cut-out pressure.
SAFETY VALVE
This valve (G) 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 the air compressor is operating, the
check valve (K) is open, allowing compressed
air to enter the air tank. When the air
compressor reaches cut-out pressure, the
check valve closes, allowing air pressure to
remain inside the air tank.

AIR INTAKE FILTER
The filter (A) is designed to clean air entering the pump. To ensure the
pump continually receives a clean, cool, and dry air
supply the filter must always be clean and the filter
intake must be free from obstructions.
AIR TANK DRAIN VALVE
The drain valve (H) is located at the base of the air
tank and is used to drain condensation at the end of
B
each use. See Draining Air Tank under MAINTENANCE.
REGULATED PRESSURE GAUGE
The regulated pressure gauge (D) indicates the
air pressure available at the outlet side of the
regulator. This pressure is controlled by the
regulator and is always less or equal to the air tank pressure.
TANK PRESSURE GAUGE
The tank pressure gauge (C)
indicates the reserve air pressure in
the tank.
UNIVERSAL QUICK CONNECT
BODY
G
The universal quick connect body
(L) accepts the three most popular
styles of quick connect plugs: Industrial, automotive, and ARO.
One hand push-to-connect operation makes connections simple
and easy.
REGULATOR

tank.
