device that allows the compressor to run in an unloaded mode. When the tank pressure drops to the preset

cut-in pressure, the pilot valve closes allowing the unloading device to close and the compressor once again pumps into the tanks.

AIR INTAKE FILTER

C

This filter (C) is designed to clean air entering the pump.

 

To ensure the pump continually receives a clean, cool,

 

and dry air supply this filter must always be clean and

 

filter intake must be free from obstructions.

 

AIR TANK DRAIN VALVES

 

English

Manual Lock (for D55170 and D55180):

The manual lock allows you to manually unload the compressor with air pressure in the tank. To operate the unloading device in the head, rotate the flip lever to an in-line position (dashed lines). Be sure to return lever to the loaded position after starting the engine or the pump will not operate at preset pressures.

PRESSURE SWITCH

 

This switch (A) is used to start or stop the air

A

compressor. Moving the switch to the "ON"

 

position will provide automatic power to the

 

pressure switch which will allow the motor to start

 

when the air tank pressure is below the factory

 

set "cut-in" pressure. When in the "ON (AUTO)"

 

The drain valves (D) are used to remove moisture from the air tank after the air compressor is shutoff.

TANK PRESSURE GAUGE

The tank pressure gauge (E) indicates air pressure in the air tank.

REGULATED PRESSURE GAUGE

The regulated pressure gauge (F) 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.

D

F

G

position, the pressure switch stops the

compressor from charging air when the air tank pressure reaches the factory set "cut-out" pressure. For ease of starting this switch also has a pressure release valve located on the side of the switch designed to automatically release compressed air from the air compressor pump head and its discharge line when the air compressor reaches "cut-out"

pressure or is shut off. Moving the switch to the "OFF" position will

open the pressure switch contacts and stop the air compressor.

 

SAFETY RELIEF VALVE

 

This valve (B) is designed to prevent system failures

 

by relieving pressure from the system when the

 

compressed air reaches a predetermined level. The

B

valve is preset by the manufacturer and must not be

removed or modified in any way.

 

PRESSURE REGULATOR

The regulator knob (G) controls the air pressure coming from the air tank.

Common Procedures

230 VOLT OPERATION

• Ensure that cord requirements have been met.

• Ensure that motor requirements have been met.

• Ensure that dual voltage switch is in the proper position if so equipped.

CORD REQUIREMENTS

If it is desired to operate your compressor at 230 volts it is also necessary to replace the 115 volt plug, supplied with the motor, with a UL/CSA listed plug suitable for 230 volts and the rated current of the compressor as shown. A 230 volt plug as shown in the diagram can be
