stores.
that a 50%-75% average duty
cycle be maintained; that is, the air
compressor pump should not run
more than 30-45 minutes in any given
hour.
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.
Branch Circuit: Circuit carrying
electricity from electrical panel to
outlet.

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 A11969
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 an extension cord,
increase the working reach of the
air hose by attaching another length
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-blade grounding plug, and a
3-slot receptacle that will accept
the plug on the product
• in good condition
• no longer than 50 feet
• 14 gauge (AWG) or larger. (Wire
size increases as gauge number
decreases. 12 AWG and 10 AWG
may also be used. DO NOT USE
16 OR 18 AWG.)
Voltage and Circuit Protection
Refer to the specification chart for the
voltage and minimum branch circuit
requirements.
Risk of Opertion.
Certain air
compressors can be operated on
a 15 amp circuit if the following
conditions are met.
1. Voltage supply to circuit must
comply with the National
Electrical Code.
2. Circuit is not used to supply any
other electrical needs.
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 - ENGA11969
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.
Regulator: Controls the air
pressure shown on the outlet
pressure gauge. Turn regulator knob
clockwise to increase pressure
and counterclockwise to decrease
pressure.
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.
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.
Description of Operation
Become familiar with these controls
before operating the unit.
On(I)/Off(O) Switch: Place this switch
in the ON (I) position to provide
automatic power to the pressure
switch and OFF (O) to remove power
at the end of each use.
Pressure Switch (not shown): 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).
Tank Pressure Gauge: The tank
pressure gauge indicates the reserve
air pressure in the tank.

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.
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.
