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 meas-
ure 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 accesso-
ry. 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 pres-
sure before the motor automatically shuts off - pro-
tecting 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 elec-
trical panel to outlet.

4. If these grounding instructions are not completely
understood, or if in doubt as to whether the com-
pressor is properly grounded, have the installation
checked by a qualified electrician.
IMPROPER GROUNDING
CAN RESULT IN ELEC-
TRICAL SHOCK.
Do not modify the plug provided. If it does
not fit the available outlet, a correct outlet
should be installed by a qualified electri-
cian.
Repairs to the cord set or plug MUST be
made by a qualified electrician.
Extension Cords
Use extra air hose instead of an extension cord to
avoid voltage drop and power loss to the motor, and
to prevent overheating.
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.)
Grounding Pin
Grounded
Outlets
Plug
Voltage and Circuit Protection
Refer to the Specification section 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 marked “D”.
If any of the above conditions cannot be met, or if
operation of the compressor repeatedly causes inter-
ruption of the power, it may be necessary to operate it
from a 20 amp circuit. It is not necessary to change
the cord set.
INSTALLATION
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 compres-
sor pump and shroud are designed to allow for proper
cooling. The ventilation openings on the compressor
are necessary to maintain proper operating tempera-
ture. Do not place rags or other containers on or near
these openings.
HOW TO SET UP YOUR UNIT
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 ground-
ing 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 ordi-
nances.
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.

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 high-
er 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 reg-
ulator 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.
Drain Valve: The drain
valve is located at the
base of the air tank and is
used to drain condensa-
tion at the end of each
use.
Cooling System (not shown): This compressor con-
tains an advanced design cooling system. At the heart
of this cooling system is an engineered fan. It is per-
fectly 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 operat-
ing, the check valve is
“open”, allowing com-
pressed air to enter the air
tank. When the air com-
pressor reaches “cut-out”
pressure, the check valve “closes”, allowing air pres-
sure to remain inside the air tank.

Technician.
Excessive tank pressure - safety
valve pops off.
Tube fittings are not tight enough. Tighten fittings where air can be
heard escaping. Check fittings
with soapy water solution. DO
NOT OVERTIGHTEN.
Air leaks at fittings.
Air leaks at pressure switch
release valve.

Technician.
Air leaks in air tank or at air tank
welds.
Defective air tank. Air tank must be replaced. Do not
repair the leak.
Do not drill into, weld or otherwise
modify air tank or it will weaken.
The tank can rupture or explode.
Air leaks between head and valve
plate.
Leaking seal. Contact a Trained Service
Technician.
Pressure reading on the regulated
pressure gauge drops when an
accessory is used.
It is normal for “some” pressure
drop to occur.
If there is an excessive amount of
pressure drop when the accessory
is used, adjust the regulator follow-
ing the instructions on page 6.
NOTE: Adjust the regulated pres-
sure under flow conditions (while
accesory is being used).
Possible defect in safety valve. Operate safety valve manually by
