AWrning
Improper operation or m.aintenance of this product could result in serious injury and/or property damage. Read and
understand all of the warnings and safety instructions provided before using this equipment.
The air compressor should be operated on a dedicated 15 amp circuit. If the circuit
does not have 15 free amps available, a larger circuit must be used. Always use
t^MITION
more air hose before utilizing extension cords. All extension cords used must be 12
gauge with a maximum length of 25 ft. The circuit fuse type must be a time delay. Low
voltaae could cause damaoe to the motor.
Risk of Moving Parts
Risk of Burns
Risk of Falling
Risk from Flying Objects
If the air compressor is in operation, all guards and covers should be attached or
installed correctly, if any guard or cover has been damaged, do not operate the
equipment until the proper personnel has correctly repaired the equipment. The power
cord should be tree of any moving parts, twisting and./or crimping while in use and
while in storage.
There are surfaces on your air compressor that while in operation and thereafter can
cause serious burns if touched. The equipment should be allowed time to cool before
any maintenance is attempted. Items such as the compressor pump and the outlet
tube are normally hot during and after operation.
Operation of the air compressor should always be in a position that is stable. Never
use the air compressor on a rooftop or elevated position that could allow the unit to fall
or be tipped over. Use additional air hose for elevated jobs.
Always wear ANSI Z87.1 approved safety glasses with side shields when the air
compressor is in use. Turn off the air compressor and drain the air tank before
performing any type of maintenance or disassembly of the hoses or fittings. Never
point any nozzle or sprayer toward any part of the body or at other people or animals.
Lnp-ortani Safety Inst-uctíons S¡ Guidelines
Risk of Breathing
Risk of
Eiectrical Shock
Risk of
Explosion or Fire
Risk of Bursting
Avoid using the air compressor in confined areas. Always have adequate space
(12 inches) on all sides of the air compressor. Also keep children, pets, and others out
of the area of operation. This air compressor doss not provide breathable air for anyone
or any auxiliary breathing device. Spraying material will always need to be in another
area away from the air compressor to not allow intake air to damage the air compressor
filter,
Never utilize the air compressor in the rain or wet conditions. Any electrical issues
or repairs should be performed by authorized personnel such as an electrician and
should comply with all national and local electrical codes. The air compressor should
also have the proper three prong groundirig plug, correct voltage, and adequate fuse
protection.
Never operate the compressor near combustible materials, gasoline or solvent vapors.
If spraying flammable materials, locate the air compressor at least 20 feet away from
the spray area. Never operate the air compressor indoors or in a confined area.
Always drain the air compressor tank daily or after each use. If the tank develops a leak,
then replace the air compressor. Never use the air compressor after a leak has been
found or try to make any modifications to the tank. Never modify the air compressor's
factory settings which control the tank pressure or any other function.

Glossary
CFM: Cubic feet per minute.
SCFM: Standard cubic feet per minute; a unit of measure
for air delivery.
PSIG: Pounds per square inch gauge; a unit of measure
for pressure.
ASME: American Society of Mechanical Engineers.
California Code: Unit may comply with California Code
462 (I) (2)/ (M) (2).
Cut-in Pressure: The air compressor will automatically
start to refill the tank when the pressure drops
below the prescribed minimum.
Cut-Out Pressure: The point at which the motor stops
wCen the tank has reached maximum air
pressure.
Code Certification: Products that bear one or more of
the following marks: UL, ULc, ETL, CSA, have
been evaluated by OSHA-certified independent
safety laboratories and meet the applicable
Undenvriters Laboratories Standards for Safety.
Duty Cycle
This is a 50% duty cycle air compressor. Do not run the air compressor more than 30 minutes of one hour. Doing so
could damage the air compressor. ■
Parts & Features
See figures below tor reference.
Air Intake Filter
Provides dean air to the pump and must always
be kept free ot debris. Check on a daily basis or
before each use,
Regulator Gauge
Indicates the outgoing air pressure to the tool and is
controlied by the regulator.
Tank Pressure Gauge
Indicates the reserve air pressure in the tank.
Pressure Switch
This controls the power to the motor and also
the cut-in/cut-out pressure settings, This switch
serves as the Auto-On/Off positions for the unit.
Pressure Relief Valve
The pressure relief valve, located on
the side of the pressure switch, is
designed to automatically release
compressed air when the air
compressor reaches cuPout
pressure. The released air should
only escape momentarily and the
valve should then close.
Tank Drain Valve
Used to drain condensation from the
air tank, Located at bottom of tank.
Tank Safety Valve
Used to allow excess tank pressure
to escape into the.atmosphere. This
valve should only open when the
tank pressure is above the
maximum rated pressure.
Regulator
The air pressure coming from the air
tank is controlled by the regulator.
To increase the pressure, turn the
knob clockwise and to decrease the
pressure turn the knob
counterclockwise.
Quick Connect
Offers a quick release feature for attaching and removing the
air hose.
Check Valve
When the pump is not in operation, the valve closes to retain
air pressure inside the tank. An interna! component.
Instaflation & Assembly
The air compressor should be turned off, unplugged from
the power source, the air bled from the tank and the unit
allowed time to cool before any maintenance is performed.
Personal injuries could occur trom moving parts, electrical
sources, compressed air or hot surfaces. The quick
connect assembly must be attached before use. Failure
to assemble correctly could result in leaks and possible
injury. If unsure of assembly instructions or you experience
difficulty in the assembly please call our toll free number
for assistance.
A WARNING
tnstailmg Wheels
The wheels and handle do not provide adequate clearance
stability or support for pulling the unit up and down stairs
or steps. The unit must be lifted or pushed up a ramp.
It may be necessary to brace or support one end of the
air compressor when attaching the wheels, because it will
have a tendency to tip,
* •
Getting Started-Location of the Air Compressor
The air compressor should always be located in a clean,
dry, and well ventilated environment. The unit should have
at minimum, 12 inches of space on each side. The air intake
filter should be free of any debris or obstructions. Check
the air filter on a daily basis to be sure it is clean and in
working order.

wire with an appropriate grounding plug. (See the figure
below.) The plug must be plugged into an outlet that is
property installed and grounded in accordance with all
local codes and ordinances. Check with a qualified
electrician or service personnel if these instructions are
not completely understood or if in doubt as to whether the
tool is properly grounded.

A WARNING
Improper installation of the grounding plug will result in a
risk of electric shock. If repair or replacement of the cord
or plug is necessary, do not connect the grounding wire to
either flat blade terminals. Check with a qualified electrician
or serviceman if the grounding instructions are not
completely understood, or if in doubt as to whether the
product is properly grounded. Do not modify the plug
provided; if it will not fit the outlet, have the proper outlet
installed by a qualified electrician.
This product is for use on a circuit having a nominal rating
of 120 volts and is factory-equipped with a specific electric
cord and plug to permit connection to a proper electric
circuit. Make sure that the product is connected to an
outlet having the same configuration as the plug. No
adapter should be used with this product. If the product
must be reconnected for use on a different type of electric
circuit, qualified service personnel should make the
reconnection.
Extension Cords
Use only a 3-wire extension cord that has a 3-blade
grounding plug, and a 3-slot receptacle that will accept
the plug on the product. Make sure your extension cord
is in good condition. When using an extension cord, be
sure to use one heavy enough to carry the current your
product will draw. Cords must not exceed 25 feet and
No. 12 AWG size must be used. An undersized cord wit!
cause a drop in line voltage resulting in loss of power and
overheating.
Break In Procedures
No break in procedure is required by the user. This
product is factory tested to ensure proper operation and
performance.
