GLOSSARY
Become familiar with these terms before operating the unit.
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.
Code Certification: Products that bear one or more of the following marks:
UL, CUL, ETL, CETL, have been evaluated by OSHA certified independent
safety laboratories and meet the applicable Underwriters Laboratories
Standards for Safety.
Cut-In Pressure: While the motor is off, air tank pressure drops as you
continue to use your accessory. When the tank pressure drops to a certain low
level the motor will restart automatically. The low pressure at which the motor
automatically restarts is called “cut-in” pressure.
Cut-Out Pressure: When an air compressor is turned on and 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.
Branch Circuit: Circuit carrying electricity from electrical panel to outlet.
DUTY CYCLE
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.
Accessories for this unit are available at the store the unit was purchased.

INSTALLATION
GROUNDING INSTRUCTIONS
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 portable air compressor is equipped with a cord having a grounding wire
with an appropriate grounding plug (see following illustrations). The plug must
be used with an outlet that has been installed and grounded in accordance
with all local codes and ordinances.
1. The cord set and plug with this unit contains a grounding pin. This plug
MUST be used with a grounded outlet.
IMPORTANT: The outlet being used must be installed and grounded in
accordance with all local codes and ordinances.
2. Make sure the outlet being used has
the same configuration as the
grounded plug. DO NOT USE AN
ADAPTER. See illustration.
3. Inspect the plug and cord before each
use. Do not use if there are signs of
damage.
4. If these grounding instructions are not completely understood, or if in
doubt as to whether the compressor is properly grounded, have the
installation checked by a qualified electrician.
IMPROPER GROUNDING CAN RESULT IN ELECTRICAL
SHOCK.
Do not modify the plug provided. If it does not fit the available outlet, a
correct outlet should be installed by a qualified electrician.
Repairs to the cord set or plug MUST be made by a qualified electrician.
HOW TO SET UP YOUR UNIT
Location of the Air Compressor
Locate the air compressor in a clean, dry and well ventilated area. The air
compressor should be located at least 12" away from the wall or other
obstructions that will interfere with the flow of air. The air compressor pump
and shroud are designed to allow for proper cooling. The ventilation openings
on the compressor are necessary to maintain proper operating temperature. Do
not place rags or other containers on or near these openings.The air filter must
be kept clear of obstructions which could reduce air flow to the air compressor.

13- ENG D26368
Extension Cords
Using extension cords is not recommended. The use of extension cords will
cause voltage to drop resulting in power loss to the motor and overheating.
Instead of using an extension cord, increase the working reach of the air hose
by attaching another length of hose to its end. Attach additional lengths of
hose as needed.
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 product
•in good condition
•no longer than 50 feet
•12 gauge (AWG) or larger. (Wire size increases as gauge number
decreases. 10 AWG and 8 AWG may also be used. DO NOT USE 14 OR
16 AWG.)
Voltage and Circuit Protection
Refer to the Parts Manual for the voltage and minimum branch circuit
requirements.
Certain air compressors can be operated on a 15 amp circuit if the following
conditions are met.
1. Voltage supply through branch circuit is 15 amps.
2. Circuit is not used to supply any other electrical needs (lights, appliances,
etc.).
3. Extension cords comply with specifications.
4. Circuit is equipped with a 15 amp circuit breaker or 15 amp time delay
fuse. NOTE: If compressor is connected to a circuit protected by fuses,
use only time delay fuses. Time delay fuses should be marked “D”in
Canada and “T”in the US.
If any of the above conditions cannot be met, or if operation of the compressor
repeatedly causes interruption of the power, it may be necessary to operate it
from a 20 amp circuit. It is not necessary to change the cord set.
Some models have dual voltage motors. These motors are
factory wired for 120 volt operation, but can be converted
to 240 volt operation. The three prong 120V cord assembly must be
replaced by a three prong 240V cord assembly to convert to 240 Volt
operation. This cord assembly may be purchased through an Authorized
Warranty Service Center.
See the label located on the motor for the correct 240 volt conversion
instructions.

OPERATION
Description of Operation
Become familiar with these controls before operating the unit.
On/Auto/Off Switch: Turn this switch ON
to provide automatic power to the pressure
switch and OFF to remove power at the
end of each use.
Pressure Switch: 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.
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).
Outlet Pressure Gauge: The outlet pressure gauge indicates the air pressure
available at the outlet side of the regulator. This pressure is controlled by the
regulator and is always less than or equal to the tank pressure.
Tank Pressure Gauge: The tank pressure gauge indicates the reserve air
pressure in the tank.
Regulator: Controls the air pressure shown on the outlet pressure gauge. Pull
the knob out and turn clockwise to increase pressure and counterclockwise to
decrease pressure. When the desired pressure is reached push knob in to lock
in place.
(if equipped) Universal Quick-Connect Body: The universal quick-connect
body accepts the three most popular styles of quick-connect plugs: Industrial,
automotive (Tru-flate), and ARO. One hand push-to-connect operation makes
connections simple and easy.

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.
Cooling System (not shown): This compressor
contains an advanced design cooling system. At
the heart of this cooling system is an engineered
fan. It is perfectly normal for this fan to blow air
through the vent holes in large amounts. You know that the cooling system is
working when air is being expelled.
Air Compressor Pump (not shown): Compresses air 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. The pressure release valve allows the motor to
restart freely. When the motor stops running, air will be
heard escaping from this valve for a few seconds. No
air should be heard leaking when the motor is running,
or continuous leaking after unit reaches “cut-out”
pressure.
Motor Overload Protector: The motor has an
automatic reset thermal overload protector. If the motor overheats for any
reason, the overload protector will shut off the motor. The motor must be
allowed to cool down before restarting. The compressor will automatically
restart after the motor cools.

rating for air tools and accessories. The regulator outlet pressure must
never exceed the maximum pressure rating.
3. Open the drain valve fully (counter-clockwise) to permit air to escape and
prevent air pressure build up in the air tank during the break-in period.
NOTE: Always drain tank on a washable surface or in a suitable container to
prevent damaging or staining surfaces.
4. Move the On/Auto/Off lever to "ON/AUTO" position. The compressor will
start.
5. Run the compressor for 15 minutes. Make sure the drain valve is open and
there is minimal air pressure build-up in tank.

pressurization may occur, causing air tank rupture or an
explosion.
1. Before starting compressor, pull the ring on the safety valve to make sure
that the safety valve operates freely. If the valve is stuck or does not
operate smoothly, it must be replaced with the same type of valve.
To Drain Tank
1. Set the On/Auto/Off lever to “OFF”.
2. Pull the regulator knob out and turn clockwise to set the outlet pressure to
zero.
3. Remove the air tool or accessory.
4. Pull ring on safety valve allowing air to bleed from the tank until tank
pressure is approximately 20 psi. Release safety valve ring.
5. Drain water from air tank by opening drain valve (counter-clockwise) on
bottom of tank.
Water will condense in the air tank. If not drained, water
will corrode and weaken the air tank causing a risk of air
tank rupture.

Air Filter Inspection and Replacement
Hot surfaces. Risk of burn. Compressor heads are
exposed when filter cover is removed. Allow compressor
to cool prior to servicing.
Keep the air filter clean at all times. Do not operate the air
compressor with the air filter removed.
A dirty air filter will not allow the compressor pump to operate at full capacity.
Before you use the compressor pump, check the air filter to be sure it is clean
and in place.
If it is dirty, replace it with a new filter. On some models,the filter may be
removed by using a pair of needle nose pliers or a screwdriver. Pull or pry out
the old filter and carefully clean the filter area. Push in the new air filter.
6. After the water has been drained, close the drain valve (clockwise). The air
compressor can now be stored.
NOTE: If drain valve is plugged, release all air pressure. The valve can then be
removed, cleaned, the reinstalled.

7. Unscrew the check valve (turn
counterclockwise) using a 7/8”open end wrench. Note the orientation for
reassembly.
8. Using a screwdriver, carefully push
the valve disc up and down. NOTE:
The valve disc should move freely
up and down on a spring which
holds the valve disc in the closed
position; if not the check valve
needs to be cleaned or replaced.
9. Clean or replace the check valve. A
solvent, such as paint or varnish
remover can be used to clean the
check valve.
10. Apply sealant to the check valve threads. Reinstall the check valve (turn
clockwise).
11. Replace the pressure release tube. Tighten nuts.
12. Replace the outlet tube and tighten nuts.
13. (if equipped) Replace shrouds and console.
14. Perform the Break-in Procedure. See “Break-in Instructions”in the
Operation section.
