reaches cut-out pressure, the check valve closes, allowing air 

pressure to remain inside the air tank.

AIR INTAKE FILTER

 

The filter (A) is designed to clean air entering the 

A

pump. To ensure the pump continually receives a 

clean, cool, and dry air supply the filter must always 

be clean and the filter intake must be free from 

obstructions.

AIR TANK 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

.

REGULATED PRESSURE GAUGE

The regulated pressure gauge (D) indicates the

G C E D

L

 

air pressure available at the outlet side of the 

regulator. This pressure is controlled by the 

regulator and is always less or equal to the air 

tank pressure.

TANK PRESSURE GAUGE

The tank pressure gauge (C) indicates the 

reserve air pressure in the tank.

UNIVERSAL QUICK CONNECT BODY

The universal quick connect body (L) 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. 

REGULATOR

The regulator knob (E) controls the air pressure coming from the air 

tank.

To Adjust Regulator:
  1. Pull regulator knob (E) out.
 2. Turn knob clockwise to increase regulated pressure and 

counter-clockwise to decrease regulated pressure.

 3. When desired pressure is shown on the regulated pressure 

gauge push knob in to lock.

WARNING: 

 Risk of Bursting. Too much air pressure causes a

hazardous risk of bursting. Check the manufacturer’s maximum

pressure rating for air tools and accessories. The regulator outlet

pressure must never exceed the maximum pressure rating.

GLOBE VALVE/AIR DISCHARGE VALVE: 

(sold separately, not 

shown) 

Opens and closes air distribution from compressor. See 

Air 

Distribution System

 paragraph under

 Installation

.

REGULATOR 

(sold separately, not shown)

An air pressure regulator or a separate air transformer which 

combines the functions of air regulation and/or moisture and 

dirt removal is recommended for most  applications. See 

Air 

Distribution System

 paragraph under

 Installation.

 

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.

MOTOR OVERLOAD PROTECTOR

The motor has a thermal overload protector. 

M

If the motor overheats for any reason, the 

overload protector will shut off the motor. The 

motor must be allowed to cool down before 

restarting. To restart:
