ENGINE
Your air compressor is powered by a Honda®gasoline engine. Most
accidents with engines can be prevented if youfollow all instructions
in this manual, the engine owner’s manual and on the engine. Some
of the most common hazards are discussed herein, along with the
best way to protect yourself and others:
• Know how to stop the engine quickly, and understand
the operation of all controls.
• Never permit anyone to operate the engine without proper
instructions.
• Do not allow children to operate the engine.
• Keep children and pets away from the area of operation.
Refuel with care: ALLOW THE ENGINE TO COOL. Gasoline is
extremely flammable, and gasoline vapor can explode. Refuel out-
doors, in a well-ventilated area, with the engine off. Never smoke
near gasoline, and keep flames and sparks away. Always store gas-
oline in an approvedcontainer. If any fuel is spilled, move compress-
or to another location before starting the engine.
Carbon Monoxide Hazards: Exhaust gas contains poisonous car-
bonmonoxide.Avoidinhalationof exhaustgas. Never run the engine
in a closed garage or confined area.

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, en-
durance 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
Inspectfor signs ofobvious orconcealed freight damage. Reportany
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 com-
pressor serial number is located on the shroud of the compressor.
Please write the serial number in the space provided in the service
section for future reference.
DEWALT Air Compressor Features
Pilot Valve
Pilot valves maintain a constant pressure range while running
continuously. The pilot valve may be used tooperate a discharge line
unloader or an unloading device in the
compressor head. The DEWALTcom-
pressor unloads through the com-
pressor head. Unloading occurs when
the receivers (tanks) reach a preset cut-
out pressure limit. The pilot valve opens, actuating the unloading
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 com-
pressor once again pumps air into the tanks.
Manual Lock
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 leverto an in-line position (dashed lines). Be sure
to return lever to the loaded position after
starting theengineor the pump will not operate
at preset pressures.
SAFETY RELIEF VALVE
This valve is designed to prevent system
failures by relieving pressure from the system
when the compressed air reaches a predeter-
mined level.The valveis preset by themanufacturer and must not be
