FEATURES
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 (I) 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
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 the air tank. When the
air compressor reaches cut-out pressure, the check valve closes,
allowing air pressure to remain inside the air tank.
TANK PRESSURE GAUGE
The tank pressure gauge (B) indicates 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. Pull the knob out and turn clockwise to increase
pressure and counterclockwise to decrease pressure. When the
desired pressure is reached push knob in to lock in place.
UNIVERSAL QUICK CONNECT BODIES
The universal Quick Connect body (E) accepts the three most
A
I
popular styles of Quick Connect plugs: Industrial, automotive, and
F
G
ARO. One hand push-to-connect operation makes connections
simple and easy.
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 each use. See Draining Air Tank under
Maintenance.
COOLING SYSTEM
This compressor contains an advanced design cooling system.
It is normal for this fan to blow air through the vent holes in large
amounts. The cooling system is working when air is expelled.
AIR COMPRESSOR PUMP
The pump compresses air into the air tank. Working air is not
available until the compressor has raised the air tank pressure
D
above that required at the air outlet.
B
PRESSURE RELEASE VALVE
C
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
E
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.
