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.
This air compressor pump is capable
of running continuously. However, to
prolong the life of your air compressor,
it is recommended that a 50%-75%
average duty cycle be maintained; that
is, the air compressor pump should
not run more than 30-45 minutes in
any given hour.

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.

11- ENG A08188
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 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.

A08188
Description of Operation
Become familiar with these controls before operating the unit.
On/Auto/Off Switch: Turn this switch
"ON/AUTO" 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.
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.
