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.
ASME: American Society of Mechanical Engineers;
made, tested, inspected and registered to meet the
standards of the ASME.
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

Cut-In Pressure: While the motor is off, air tank
pressure drops as you continue to use your acces-
sory. When the tank pressure drops to the factory
set low pressure 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 factory set 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.

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
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 com-
pletely understood, or if in doubt as to whether
the compressor is properly grounded, have the
installation checked by a qualified electrician.

INSTALLATION
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 locat-
ed at least 12" away from the wall or other obstruc-
tions 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 oper-
ating temperature. Do not place rags or other con-
tainers on or near these openings.The air filter must
be kept clear of obstructions which could reduce air
flow to the air compressor.
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 electrician.
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.)
Voltage and Circuit Protection
Refer to the Parts Manual for the voltage and mini-
mum 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.

OPERATION
Know Your Air Compressor
READ THIS OWNER’S MANUAL AND SAFETY RULES BEFORE OPERATING YOUR UNIT. Compare the illus-
trations with your unit to familiarize yourself with the location of various controls and adjustments. Save this
manual for future reference.
Drain Valve (not shown): The drain valve is located
at the base of the air tank and is used to drain con-
densation at the end of each use.
Motor Thermal Overload Protector (not shown):
The electric motor has an automatic thermal over-
load 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 (A): Turn this switch ON to
provide automatic power to the pressure switch and
OFF to remove power at the end of each use.
Air Intake Filter (not shown): This filter is
designed to clean air coming into the pump. This fil-
ter must always be clean and ventilation openings
free from obstructions. See "Maintenance".
Air Compressor Pump (not shown): Compresses
air into the air tank.
Check Valve (not shown): When the air compres-
sor 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 (not shown): The pres-
sure release valve located on the side of the pres-
sure 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.
Pressure Switch (B): The pressure switch automati-
cally 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 (C): 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 set-
ting).
Outlet Pressure Gauge (D): The outlet pressure
gauge indicates the air pressure available at the out-
let side of the regulator. This pressure is controlled
by the regulator and is always less than or equal to
the tank pressure. All four outlets operate at this
pressure.
Tank Pressure Gauge (E): The tank pressure
gauge indicates the reserve air pressure in the tank.
The “quadraport” is equipped with an tank pressure
gauge to be read at a remote location.
Regulator (F): 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.

not work properly, over-
pressurization may occur, causing air tank
rupture or an explosion. 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 oper-
ate 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 approximate-
ly 20 psi. Release safety valve ring.
5. Drain water from air tank by opening drain valve
(counter-clockwise) on bottom of tank.

NOTE: See “Operation” section for the location of controls.
To ensure efficient operation and longer life of the air compressor outfit, a routine maintenance schedule
should be prepared and followed. The following routine maintenance schedule is geared to an outfit in a nor-
mal working environment operating on a daily basis. If necessary, the schedule should be modified to suit the
conditions under which your compressor is used. The modifications will depend upon the hours of operation
and the working environment. Compressor outfits in an extremely dirty and/or hostile environment will require
a greater frequency of all maintenance checks.
Unit cycles automatically when power is on. When performing maintenance, you
may be exposed to voltage sources, compressed air, or moving parts. Personal
injuries can occur. Before performing any maintenance or repair, disconnect power source from the
compressor and bleed off all air pressure.

3. If dirty, rinse air filter with warm water and
squeeze dry.
4. Replace air filter and air filter cover.
NOTE: If the air filter is extremely dirty it will need to
be replaced. Refer to the “Repair Parts” for the cor-
rect part number.
Motor
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 restart-
ing. The compressor will automatically restart after
the motor cools.
If the overload protector shuts the motor off fre-
quently, check for a possible voltage problem. Low
voltage can also be suspected when:
1. The motor does not get up to full power or
speed.
2. Fuses blow out when starting the motor; lights
dim and remain dim when motor is started and

7. Unscrew the check valve (turn counterclock-
wise) 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. Replace the shroud and air filter.
14. Perform the Break-in Procedure. See “Break-in
Procedure” in the Operation section.
SERVICE AND ADJUSTMENTS
Unit cycles automatically when power is on. When doing Maintenance, you may be
exposed to voltage sources, compressed air or moving parts. Personal injuries can occur.
Before performing any Maintenance or repair, unplug the compressor and bleed off all air pressure.
ALL MAINTENANCE AND REPAIR OPERATIONS NOT LISTED MUST BE PERFORMED
BY TRAINED SERVICE TECHNICIAN.
To Replace or Clean Check Valve
1. Release all air pressure from air tank. See “To
Drain Tank” in the Maintenance section.
2. Unplug outfit.
3. Using a phillips screwdriver remove the air filter
cover.
4. Remove the rear shroud using T-20 torx wrench.
5. Using an adjustable wrench loosen outlet tube
nut at air tank and pump. Carefully move outlet
tube away from check valve.

STORAGE
Before you store the air compressor, make sure you
do the following:
1. Review the "Maintenance" section on the
preceding pages and perform scheduled
maintenance as necessary.
2. Set the “ON/AUTO” lever to “OFF”.
3. Turn the regulator counterclockwise and set the
outlet pressure to zero.
4. Remove the air tool or accessory.
TANK CAN CONTAIN 175
PSI OF AIR PRESSURE.
ALWAYS STAND CLEAR WHEN BLEEDING
AIR THROUGH SAFETY VALVE.
5. Pull ring on safety valve allowing air to bleed
from the tank until tank pressure is
approximately 20 psi. Release safety valve ring.
6. Drain water from air tank by opening drain cock
valve 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.
7. After the water has been drained, close the
drain cock or drain valve.
NOTE
If drain cock valve is plugged, release all air
pressure. The valve can then be removed,
cleaned, then reinstalled.
8. Protect the electrical cord and air hose from
damage (such as being stepped on or run over).
9. While lifting tab (A) rotate handle (B) into
storage position.
10. Store the air compressor in a clean and dry
location.
To Transport unit
1. Fold handles into storage position.
The unit is too heavy to
be lifted by one person.
Use two people to lift unit.
2. Locate the lift handles (C) on each side of the
unit.
3. With a person on each side, carefully lift unit
using handle (B) and lift handle (C).
