temporary adapter should be used only until a properly grounded outlet
can be installed by a qualified electrician, The green-colored rigid ear,
lug, and the like, extending from the adapter must be connected to a
permanent ground such as a properly grounded outlet box.

Introduction
Congratulations on the purchase of your new D
E
WALT 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 D
E
WALT 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
