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.

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.

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.
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.

_ _Outlets
Grou_d_ing Pin
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.
D28900 10-ENG

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.
Attach extra air hoses at the air outlet
instead of using extension cords.
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 Specification Chart 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.

Know Your Air Compressor
READ THIS OWNER'S MANUAL AND SAFETY RULES BEFORE OPERATING
YOUR UNIT. Compare the illustrations with your unit to familiarize yourself with
the location of various controls and adjustments. Save this manual for future
reference.
Safety Valve
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.
D28900
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.
Drain
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.
12_ENG

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.
NOTE: Pull coupler back until it clicks
to prevent air from escaping through
the quick connect.
How to Use Your Unit
How to Stop:
1. Set the On/Auto/Off lever to
