Outlets
Plug
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 A08595
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.

12- ENG

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.
Turn the knob clockwise to increase
pressure and counterclockwise to
decrease pressure.
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.
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.
