Introduction

Congratulations on the purchase of your new DEWALT Air Com- pressor! You can be assured that this tool has been constructed with the highest level of precision and accuracy. Each component has been rigorously tested by technicians to ensure the quality, endurance and performance of this air compressor.

By reading and following the safety, operation, maintenance and troubleshooting steps described in this manual, you will receive years of trouble-free operation.

The manufacturer reserves the right to make changes in price, color, materials, equipment specifications or models at any time without notice.

Inspection of Compressor

Inspect for signs of obvious or concealed freight damage. Report any damage to the delivering freight carrier immediately. Be sure that all damaged parts are replaced and any mechanical problems are corrected prior to the operation of the air compressor. The air

compressor serial number is located on the deck of the air compressor and pump bearing cap. Please write the serial number in the space provided in the service section for future reference.

Features

DUAL CONTROL

This feature allows the compressor to operate in either the constant run or the stop/start mode of operation. The pilot valve is used to control the compressor when operating in the constant run mode. The pressure switch is used to control the compressor when operating in the stop/start mode. The mode of operation is determined by the amount of time the compressor will be required to supply air. If the demand for air is infrequent, then the unit should be set up for stop/start operation to minimize unnecessary run time and to save energy. If there is a frequent or extended demand for air, and/or the unit is located in a remote area where access to the compressor is difficult, the unit should be set up for constant run to minimize the number of times the motor must start in an hour to ensure good motor life.

DUAL VOLTAGE

This feature allows the compressor to operate in either 120 or 240 volt environments. The advantage of running in the 240 volt range is a lower current draw. Lower current draw may be necessary in areas with a poor power source. Lower current also reduces operating costs. If running in the 240 volt mode, the plug end must be replaced with the appropriate plug.

PILOT VALVE

Pilot valves are used to maintain a constant pressure range while running continuously. The pilot valve may be used to operate a discharge line unloader or an unloading device in the compressor head. The DEWALT compressor unloads through the compressor head. Unloading occurs when the receivers (tanks) reach a preset cut-out pressure. The pilot valve opens, actuating the unloading
