GLOSSARY
CFM: Cubic feet per minute.
SCFM: Standard cubic feet per minute; a unit of measure of
air delivery.
PSIG: Pounds per square inch gauge; a unit of measure of
pressure.
ASME: American Society of Mechanical Engineers; made,
tested, inspected and registered to meet the standards of
ASME.
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 of Safety.
California Code: Unit may comply with California Code 462
(L) (2)/(M) (2). Specification/model label is on the side of the
tank on units that comply with California Code.
Cut-In Pressure: While the motor is off, air tank pressure
drops as you continue to use your accessory or air tool. When
the tank pressure drops to a certain low level the motor will
restart automatically. The low pressure at which the motor
automatically re-starts is called “cut-in pressure.”
Cut-Out Pressure: When you turn on your air compressor
and it begins to run, air pressure in the air tank begins to build.
It builds to a certain high pressure before the motor automatically shuts off - protecting your air tank from pressure higher
than its capacity. The high pressure at which the motor shuts
off is called “cut-out pressure.”
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 air 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.
GENERAL INFORMATION
You have purchased an air compressor unit consisting of an
aluminum 2 cylinder, single-stage air compressor pump (with
cast iron sleeves), an air tank, wheels, handle, associated
controls and instruments.
Your air compressor can be used for operating paint spray
guns, air tools, caulking guns, grease guns, air brushes,
sandblasters, inflating tires and plastic toys, spraying weed
killers, insecticides, etc. An air pressure regulator is required
for most of these applications.
An air line filter is usually required for removal of moisture and
oil vapor in compressed air when a paint spray gun is used.
An in-line lubricator is usually required for air tools to prolong
tool life.
Separate air transformers which combine the functions of air
regulation and/or moisture and dirt removal should be used
where applicable.
ON-RECEIPT INSPECTION
Each air compressor outfit is carefully tested and checked
before shipment. With improper handling, damage may result
in transit and cause problems in compressor operation.
Immediately upon arrival, check equipment for both concealed and visible damages to avoid expenses being incurred
to correct such problems. This should be done regardless of
any visible signs of damage to the shipping container. If this
product was shipped directly to you, report any damages to
carrier and arrange for inspection of goods immediately.

Air Power Authorized Warranty Service Center, call our toll

DESCRIPTION OF OPERATION
Drain Valve: The drain valve is located at the base of the air
tank and is used to drain condensation at the end of each use.
Motor Thermal Overload Protector: The electric motor has
an automatic thermal overload protector. If the motor overheats for any reason, the thermal overload protector will shut
off the motor. The motor must be allowed to cool before
restarting.
ON/AUTO - OFF Switch (Pressure Switch): Turn this
switch ON to provide automatic power to the pressure switch
and OFF to remove power at the end of each use. The pressure
switch automatically starts the motor when the air tank
pressure drops below the factory set “cut-in” pressure. It
stops the motor when the air tank pressure reaches the
factory set “cut-out” pressure.
Air Intake Filter: This filter is designed to clean air coming
into the pump. This filter must always be clean and ventilation
openings free from obstructions. See "Maintenance".
Air Compressor Pump: To compress air, the pistons moves
up and down in the cylinder. On the downstroke, air is drawn
in through the air intake 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, through the outlet tube, through the check
valve and into the air tank. Working air is not available until
the compressor has raised the air tank pressure above that
required at the air outlet.
Check Valve: When the air compressor is operating, the
check valve is “open”, allowing compressed air to enter the
air tank. When the air compressor reaches “cut-out” pressure, the check valve “closes”, allowing air pressure to remain
inside the air tank.
Pressure Release Valve: The pressure release valve located on the side of the pressure switch, is designed to
automatically release compressed air from the compressor
head and the outlet tube when the air compressor reaches
“cut-out” pressure or is shut off. If the air is not released, the
motor will try to start, but will be unable to. The pressure
release valve allows the motor to restart freely. When the
motor stops running, air will be heard escaping from the valve
for a few seconds. No air should be heard leaking when the
motor is running, or continuous leaking after unit reaches cutout pressure.
Safety Valve: If the pressure switch does not shut off the air
compressor at its cut-out pressure setting, the safety valve
will protect against high pressure by “popping out” at its
factory set pressure (slightly higher than the pressure switch
cut-out setting).
