FEATURES (Fig. 1)
ON/OFF SWITCH
Place this switch (A) in the ON position to
provide automatic power to the pressure
switch and OFF to remove power at the
end of each use.
PRESSURE SWITCH
The pressure switch (J) 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.
PRESSURE RELEASE VALVE
The pressure release valve located on the side of the pressure
switch, is designed to automatically release compressed air from
the compressor head and the outlet tube when the air compressor
reaches cut-out pressure or is shut off. The pressure release valve
allows the motor to restart freely. When the motor stops running,
air will be heard escaping from this valve for a few seconds. No air
should be heard leaking when the motor is running or after the unit
reaches cut-out pressure.
SAFETY VALVE
If the pressure switch does not shut off the air compressor at its cut-
out pressure setting, the safety valve (G) will protect against high
pressure by popping out at its factory set pressure (slightly higher
than the pressure switch cut-out setting).
CHECK VALVE
When the air compressor is operating, the check
valve (F) is open, allowing compressed air to enter
G J
the air tank. When the air compressor reaches cut-
out pressure, the check valve closes, allowing air
pressure to remain inside the air tank.
A
TANK PRESSURE GAUGE
The tank pressure gauge (B) indi-
cates the reserve air pressure in
the tank.
OUTLET PRESSURE GAUGE
The outlet pressure gauge (C)
indicates the air pressure available
at the outlet side of the regulator. This pressure is controlled by the
regulator and is always less than or equal to the tank pressure.
REGULATOR
The regulator (D) controls the air pressure shown on the outlet
pressure gauge. Turn regulator knob clockwise to increase pressure
and counterclockwise to decrease pressure.
UNIVERSAL QUICK CONNECT BODIES (IF EQUIPPED)
The universal quick connect body (E) 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. The two quick connect bodies allow the use of two
tools at the same time.
