FEATURES (Fig. 1)
ON/OFF SWITCH
Place this switch (L) in the ON position to	L
provide automatic power to the pressure
switch and OFF to remove power at the
end of each use.
PRESSURE SWITCH	H
The pressure switch (H) automatically
starts the motor when the air tank pres-
sure drops below the factory set cut-in

pressure. It stops the motor when the air tank pressure reaches the factory set cut-outpressure.

SAFETY VALVE

If the pressure switch does not shut off the air

compressor at its cut-out pressure setting, the

REGULATED PRESSURE GAUGE

The regulated pressure gauge (D) indicates the air pressure avail- able at the outlet side of the regulator. This pressure is controlled by the regulator and is always less than or equal to the tank pres- sure.

REGULATOR

The regulator (F) controls the air pressure shown on the regulated pressure gauge. Turn regulator knob clockwise to increase pres- sure and counterclockwise to decrease pressure.

UNIVERSAL QUICK CONNECT BODIES

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.

safety valve (G) will protect against high pressure
by popping out at its factory set pressure (slightly	G
higher than the pressure switch cut-out setting).

CHECK VALVE

When the air compressor is operating, the check valve is open, allowing compressed air to enter the air tank. When the air

DRAIN VALVE

The drain valve (M) is located at the base of the air tank and is used to drain condensa- tion at the end of each use. See Draining

Air Tank under Maintenance.

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 (K) indi-	E
cates the reserve air pressure in
the tank.

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.
