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. !0 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 suppiy through branch
circuit is 15 amps.
2. Circuit is not used to supply any
other electrica! 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 famiIiarize yourself with
the location of various controls and adjustments. Save this manual for future
reference. On/Auto/Off Switch
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 wil! 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 outtet
pressure gauge indicates the air
pressure avaiIable 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 outiet pressure gauge.
Turn the knob clockwise to increase
pressure and counterclockwise to
decrease pressure.
Drain VaBve: The drain valve is
located at the base of the air tank
and is used to drain condensation at
the end of each use.
CooBing 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.
A08595 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.
Oheek 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.
