correct outlet should be installed
by a qualified electrician. Repairs
to the cord set or plug MUST be
made by a qualified
electrician.
11- ENG D27304
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.
Instead of using extension cords
attach extra air hoses to each other
starting at the air outlet.
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 sat.

Description of Operation
Become familiar with these controls
before operating the unit.
Orv'Aute/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 "cutqn"
pressure, It stops the motor when the
air tank pressure reaches the factory
sat "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.
Regulater: 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:
Ihe universal quick-connect body
accepts the three most popular styles
of quick-connect plugs: Industrial,
automotive (Tru-flate}, and ARC, One
hand push-to-connect operation
makes connections simple and easy.
Brain 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.
