Repairs to the cord set or pmug
MUST be made by a quamified
emectrician.
11- ENG A09708

Extension Cords
Using extension cords is not
recommended. The use of extension
cords wiII cause voltage to drop
resulting in power Ioss to the motor
and overheating.
Instead of using an extension cord,
increase the working reach of the
air hose by attaching another Iength
of hose to its end. Attach additional
lengths of hose as needed.
If an extension cord must be used,
be sure it is:
® a 3-wire extension cord that has
a 3-bIade grounding ptug, 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.)
Vomtage 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 famiIiarize 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/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 vaIve 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 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 Iess 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.
Universal Quick-Connect Body:
The universal quick-connect body
accepts the three most popular styles
of quick-connect plugs: industrial,
automotive (Tru-fiate), and ARC. One
hand push-to-connect operation
makes connections simple and easy.
Brain Vamve:The drain valve is
located at the
base of the
air tank and is
used to drain Drain
condensation Valve
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 bIow air through the vent hotes
in large amounts. You know that the
cooling system is working when air is
being expelled.
13= ENG A09708

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",
a!lowing
compressed
air to enter Check
the air tank.
When the air
compressor reaches "cut-out"
pressure, the check valve "closes",
a!lowing air pressure to remain inside
the air tank.
Pressure Release Vatve: 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.
Air Intake Filter (not shown): This
filter is designed to clean air coming
into the pump. This filter must
always be clean and ventilation
openings free from obstructions. See
"Maintenance".
Motor Overload Protector: The
motor has an automatic reset
thermal overload protector. If the
motor overheats for any reason, the
overload protector will shut off the
motor. The motor must be allowed
to cooI down before restarting. The
compressor will automatically restart
after the motor cools.
How to Use Your Unit
How to Stop:
