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 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.

HOW TO SET UP YOUR UNiT iMPROPERGROUNDING
CAN RESULT iN ELEC=
Location of the Air Compressor TRICAL SHOCK.
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.The air filter must be kept clear of
obstructions which could reduce air flow to the air
compressor.
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.
_Grounded
/ Outlets
Grounding Pin
.
Inspect the plug and cord before each use. Do
not use if there are signs of damage.
.
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.
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.)
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 isequipped 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 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.

Know Your Air Compressor
READ THIS OWNER'S MANUAL AND SAFETY RULES BEFORE OPERATING YOUR UNIT. Compare the illustra-
tions with your unit to familiarize yourself with the location of various controls and adjustments. Save this manual
for future reference.
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 operating, the
check valve is "open", allow-
ing 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
pressure release valve located Release
on the side of the pressure
Valve
switch, is designed to auto-
matically 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 leak-
ing when the motor is running, or continuous leaking
after unit reaches "cut-out" pressure.

complete compressor pump has been replaced.
1. Make sure the On/Auto/Off lever is in the "OFF"
position.
NOTE: If quick connect is installed, pull coupler back
until it clicks to prevent air from escaping through the
quick connect.
following break-in instructions are
4. Move the On/Auto/Off lever to "ON/AUTO" posi-
tion. 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.
6. After 15 minutes close the drain valve (clockwise).
The air receiver will fill to "cut-out" pressure and
the motor will stop.
The compressor is now ready for use.
Before Each Start=Up:
1. Place On/Auto/Off lever to "OFF".
.
Pull regulator knob out, turn counter-clockwise
until it stops. Push knob in to lock in place.
.
Attach hose and accessories. NOTE: The hose or
accessory will require a quick connect plug if the
air outlet is equipped with a quick connect.
Too much air pressure
causes a hazardous risk of
bursting. Check the manufacturer's maximum
pressure rating for air tools and accessories.
The regulator outlet pressure must never
exceed the maximum pressure rating.
Switch
.
Plug the power cord into the correct branch circuit
receptacle. (Refer to Voltage and Circuit
Protection paragraph in the Installation section of
this manual.)
.
Open the drain valve
fully (counter-clock-
wise) to permit air to
escape and prevent air
pressure build up in
the air tank during the
break-in period.
How to Start:
1. Turn the On/Auto/Off lever to "AUTO" and allow
tank pressure to build. Motor will stop when tank
pressure reaches "cut-out" pressure.
2. Pull the regulator knob out and turn clockwise to
increase pressure. When the desired pressure is
reached push knob in to lock in place. The com-
pressor is ready for use.
