FOR FUTURE USEFEATURES

FEATURES

UNLOADER VALVE

When the maximum air tank pressure is obtained, the unloader

valve (H) will blow-off. This will cause the compressor to exhaust

the air to the atmosphere and not the tank.

Manual Lock: The manual lock allows you to

OPEN

CLOSED

manually unload the compressor with air

pressure in the air tank. To operate the

manual lock:

Rotate the manual lock unloaderlever to the

open position to prevent air tank pressure

buildup. Rotate manual lock unloader lever to

the closed position after starting the engine to allow air tank pressure

to build. NOTE: Air will not build in tank when manual lock unloader

lever in the open position.

SAFETY VALVE

This valve (I) is designed to prevent system failures

by relieving pressure from the system when the

compressed air reaches a predetermined level. The

valve is preset by the manufacturer and must not be

removed or modified in any way.

AIR INTAKE FILTER

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

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 (J) is used to remove moisture J

from the air tank after the air compressor is shut

off.

See Draining Air Tank under

Maintenance.

English

AIR TANK PRESSURE GAUGE

The air tank pressure gauge (D) indicates

air pressure in the air tank.

REGULATED PRESSURE GAUGE

The regulatedpressure gauge(E)indicates

the 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.

REGULATOR

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

tank.

Adjusting Regulator

1. Pull regulator knob (F) out.

2. Turn knob clockwise to increase regulated pressure and

counterclockwise to decrease regulated pressure.

3. When desired pressure is shown on the regulated pressure

gauge push knob in to lock.

THROTTLE CONTROL (Fig. 1)

When maximum air tank pressure is reached and the unloader valve

vents air, it activates the throttle control (K) on the engine. This gas

saving feature holds the engine at a factory-set idling speed until air

pressure in the air tank drops to reset pressure. The unloader valve

then reactivates the throttle control and accelerates the engine to

full throttle.

UNIVERSAL QUICK CONNECT BODIES

The universal quick connect body (G) 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.
