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 (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.
REGULATED 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 regulated
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 BODY
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.
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.

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
above that required at the air outlet.
