Tank Pressure Gauge

The tank pressure gauge (B) indicates the reserve air pressure in the tank.

Features (Fig. 1)

Auto/Off Switch

Place this switch (A) in the AUTO (I) position to provide automatic power to the pressure switch and OFF (O) to remove power at the end of each use.

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

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.

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).

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	H

This compressor contains an advanced design cooling system. It is normal for this fan to blow air through the vent holes in large

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.

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.
