AND CAUSE RUPTURE OR EXPLOSION.
ATTACHMENTS & ACCESSORIES:
EXCEEDING THE PRESSURE RATING OF AIR TOOLS, SPRAY
GUNS, AIR OPERATED ACCESSORIES, TIRES AND OTHER
INFLATABLES CAN CAUSE THEM TO EXPLODE OR FLY
APART, AND COULD RESULT IN SERIOUS INJURY.
MGP-FA752-3A
4 — ENG
FOR ESSENTIAL CONTROL OF AIR PRESSURE, YOU MUST
INSTALL A PRESSURE REGULATOR AND PRESSURE GAUGE
TO THE AIR OUTLET OF YOUR COMPRESSOR. FOLLOW THE
EQUIPMENT MANUFACTURERS RECOMMENDATION AND
NEVER EXCEED THE MAXIMUM ALLOWABLE PRESSURE
RATING OF ATTACHMENTS. NEVER USE COMPRESSOR TO
INFLATE SMALL LOW-PRESSURE OBJECTS SUCH AS
CHILDREN’S TOYS, FOOTBALLS, BASKETBALLS. ETC.
HAZARD
RISK FROM FLYING OBJECTS
WHAT CAN HAPPEN
THE COMPRESSED AIR STREAM CAN CAUSE SOFT TISSUE

ALWAYS PLACE COMPRESSOR ON A PROTECTIVE MAT WHEN
TRANSPORTING TO PROTECT AGAINST DAMAGE TO VEHICLE
FROM LEAKS. REMOVE COMPRESSOR FROM VEHICLE
IMMEDIATELY UPON ARRIVAL AT YOUR DESTINATION.
GLOSSARY
SCFM or CFM: Standard Cubic Feet per Minute; a unit of
measurement of air delivery.
PSIG or PSI: Pounds per square inch gauge.
U.L. Listed: Products with the U.L. mark are listed by
Underwriters Laboratories, Inc. (U.L.). Samples of these
products have been evaluated by U.L. and meet the
applicable U.L. Standards for Safety.
DUTY CYCLE
All DeVilbiss Air Power manufactured air compressors
should be operated on not more than a 50% duty cycle. This
means an air compressor that pumps more than 50% of one
hour, is considered misuse, because the air compressor is
undersized for the required air demand. Maximum compressor pumping time per hour is 30 minutes.
DESCRIPTION OF OPERATION
Air Compressor Pump: To compress air, the piston
moves up and down in the cylinder. On the downstroke,
air is drawn in through the air intake muffler (valves). The
exhaust valve remains closed. On the upstroke of the
piston, air is compressed. The intake valves close and
compressed air is forced out through the exhaust valve and
then through the air hose.
Adjustable Pressure Valve: The pressure valve controls
the amount of pressure going from the air compressor to
the accessory. The pressure adjusting valve can be used
to set approximate pressure between 10 and 125 P.S.I.
(125 P.S.I. is the highest pressure this compressor will
deliver). It is normal for the adjustable pressure valve to
release air during operation.
Accumulator Tank: Your accumulator tank is equipped
with a relief (pop-off) valve to prevent an over pressure
condition in the tank. This 2 gallon tank is not designed to
store air, but rather to provide the additional volume of
compressed air necessary to operate a wide variety of air
tools. When starting your compressor, attach the tool to
the hose, set the pressure adjusting valve at the required
pressure, wait a few moments until the tank fills with air.
You will know the tank is filled when you hear air bleeding
through the pressure adjusting valve. Depending on the
type and size of tool being used, you will occasionally need
to wait for the tank to refill before continuing. When you are
finsihed or changing tools, turn the compressor switch off
and set the pressure adjusting valve to 10 PSI and wait for
the tank to discharge completely.
ALWAYS SET THE PRESSURE VALVE AT OR BELOW
THE REQUIRED PRESSURE FOR THE ACCESSORY
BEING USED BEFORE STARTING YOUR COMPRESSOR. FOR INFLATION OR OTHER USES REQUIRING
ACCURATE PRESSURE, USE A PRESSURE GAUGE.

MGP-FA752-3A
INSTALLATION AND BREAK-IN PROCEDURES
Location of the Air Compressor
Your compressor comes to you completely assembled
and ready for use. Operate the air compressor in a dry,
clean, cool and well ventilated area. The air compressor
pump and case are designed to allow for proper cooling.
Clean or blow off dust or dirt that collects on the air
compressor. A clean air compressor runs cooler and
provides longer service. The ventilation openings on your
air compressor are necessary to maintain proper operating
temperature. Do not place rags or other containers on or
near these openings.
Extension Cords
Use extra air hose instead of an extension cord to avoid
voltage drop and power loss to the motor. Low voltage can
cause damage to the motor.
Do not modify the plug that has been provided. If it
does not fit the available outlet, the correct outlet
should be installed by a qualified electrician.
If repairing or replacing cord or plug, the grounding
wire must be kept separate from the current-carrying
wires. Never connect the grounding wire to a flat blade
plug terminal. The grounding wire has insulation with
an outer surface that is green - with or without yellow
stripes.
If these grounding instructions are not completely
understood, or if in doubt as to whether the compres
sor is properly grounded, have the installation checked
by a qualified electrician.
120 Volt Models
If an extension cord must be used, be sure it is:
• a 3-wire extension cord that has a 3-blade grounding
plug, and a 3-slot receptacle that will accept the plug on
the compressor
• in good condition
• no longer than 50 feet
• 14 gauge (AWG) or larger. (Wire size increases as
gauge number decreases.) 12 AWG, 10 AWG and 8
AWG may also be used. DO NOT USE 16 OR 18 AWG.
120 Volts, 15 Amps
GROUNDING INSTRUCTIONS
Air Hose
RISK OF ELECTRICAL SHOCK! In the event of
a short circuit, grounding reduces the risk of
shock by providing an escape wire for the
electric current. This air compressor must be
properly grounded.
The air compressor is equipped with a cord having a
grounding wire with an appropriate grounding plug. The
plug must be used with an outlet that has been installed
and grounded in accordance with all local codes and
ordinances. The outlet must have the same configuration
as the plug. See illustration. DO NOT USE AN
ADAPTER.
Inspect the plug and cord before each use. Do not use if
there are signs of damage.
IMPROPER GROUNDING CAN RESULT IN
ELECTRICAL SHOCK.
MGP-FA752-3A
8 — ENG
The air hose attached to your comporessor has an integral
pressure adjusting valve at the working end of the hose.
Should service or replacement be required, make sure that
the pressure adjusting valve is present in the air hose line.
It is normal for the adjustable pressure valve to release air
during operation.
DO NOT REPLACE THE HOSE WITH STANDARD HOSE THAT IS NOT EQUIPPED WITH
THE PRESSURE ADJUSTING VALVE. THE
APPROPRIATE HOSE ASSEMBLY FOR YOUR
COMPRESSOR IS AVAILABLE AT SEARS.
Do not allow hose to become kinked or
pinched at any time. This is important to avoid
damage to your compressor and to maintain
pressure adjusting valve control.
OPERATING PROCEDURES
1. Before plugging in the air compressor, set the adjustable pressure valve to "10" PSI. Make sure the "ON/
OFF" switch is in the "OFF" position.
2. Connect the air tool or accessory to the air hose.
Tighten securely.
3. Plug the power cord into the grounded outlet.
4. Start the compressor by setting the "ON/OFF" switch
to the "ON" position.
5. Check the manufacturer's maximum pressure rating
for the air tool, accessory or vehicle tire being used.
The air compressor outlet pressure must never exceed the maximum pressure rating.
6. Slowly increase the pressure setting of the adjustable
pressure valve. You should be able to hear and feel
air pressure being relieved by the adjustable pressure
valve. If pressure is not being relieved, turn the air
compressor off immediately. The pressure valve must
be replaced.
TOO MUCH AIR PRESSURE COULD CAUSE AN
AIR TOOL OR VEHICLE TIRE TO RUPTURE OR
EXPLODE. CAREFULLY FOLLOW STEPS 5 AND 6
EACH TIME YOU USE YOUR COMPRESSOR.
Compressed air from the outfit may contain water
condensation. Do not spray unfiltered air at an
item that could be damaged by moisture. Some
air operated tools or devices may require filtered
air. Read the instructions for the air tool or device.
STORAGE
When you have finished using the air compressor:
1. Set the "ON/OFF" switch to "OFF" and unplug the
cord.
4. After the water has been drained, close the drain cock
or drain valve.
2. Relieve all pressure from the air compressor head and
air hose by setting the adjustable pressure valve to 10
P.S.I.
5. Protect the electrical cord and air hose from damage by
winding them loosely around the air compressor.
3. Drain water from air tank.
6. Store the air compressor in a clean and dry location.
