DUAL CONTROL
Dual control allows the compressor to operate in the constant
run or the stop/start mode of operation. The unloader valve (H)
is used to control the compressor when operating in the constant
run mode. The pressure switch is used to control the compressor
when operating in the stop/start mode. The mode of operation is
determined by the amount of time the compressor will be required to
supply air. If the demand for air is infrequent, then the unit should be
operated in the stop/start mode to minimize unnecessary run time
and to save energy. If there is a frequent or extended demand for
air, and/or the unit is located in a remote area where access to the
compressor is difficult, the unit should be operated in the constant
run mode to minimize the number of times the motor must start in
an hour to ensure good motor life.
UNLOADER VALVE
When the maximum air tank pressure is
H
obtained, the unloader valve (H) will blow-off.
This will cause the compressor to exhaust the
air to the atmosphere and not the tank. The
valve is preset by the manu facturer and must not
be removed or modified in any way.
PRESSURE SWITCH
The pressure switch (M) 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. The pressure release valve located on the side of the pres-
sure 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.
SAFETY VALVE
This valve (I) is designed to prevent system
I
failures by relieving pressure from the system
when the compressed air reaches a predeter-
mined level. The valve is preset by the manu-
facturer and must not be removed or modified in
any way.

AIR INTAKE FILTER
The filter (A) is designed to clean air entering the pump.
A
To ensure the pump continually receives a clean, cool
and dry air supply the filter must always be clean and
the filter intake must be free from obstructions.
AIR TANK DRAIN VALVE
The drain valve (J) is used to remove
J
moisture from the air tank after the air
compressor is shut off.

REGULATED PRESSURE GAUGE
The regulated pressure gauge (E)
indicates the air pressure available at
the outlet side of the regulator. This
pressure is controlled by the regulator and is always less or equal to
the air tank pressure.
REGULATOR
The regulator knob (F) controls the air pressure coming from the air
tank.
To Adjust Regulator:
1. Pull regulator knob (F) out.
2. Turn knob clockwise to increase regulated pressure and
counterclockwise to decrease regulated pressure.
3. When desired pressure is shown on the regulated pressure
gauge push knob in to lock.
MOTOR OVERLOAD PROTECTOR
The motor has a thermal overload protector. If the motor overheats
for any reason, the overload protector will shut off the motor. The
motor must be allowed to cool down before restarting. To restart:
1. Set the On/Off switch to OFF and unplug unit.
2. Allow the motor to cool.
3. Depress the red reset button on the motor.
4.
Plug the power cord into the correct branch circuit receptacle.
5. Set the On/Off switch to ON/AUTO position.

CFM: Cubic feet per minute.
SCFM: Standard cubic feet per minute; a unit of measure of air
delivery.
PSI: Pounds per square inch; a unit of measure of pressure.
Code Certification: Products that bear one or more of the following
marks: UL, CUL, ETL, CETL, have been evaluated by OSHA
certified independent safety laboratories and meet the appli-
cable Underwriters Laboratories Standards for Safety.
California Code: Unit may comply with California Code 462 (l) (2)/
(M) (2). Specification/model label is on the side of the air tank
on units that comply with California Code.
Cut-In Pressure: While the motor is off, air tank pressure drops
when accessory is used. 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: The circuit carrying electricity from electrical panel
to outlet.
Duty Cycle: This air compressor pump is capable of running con-
tinuously. However, to prolong the life of your air compressor,
it is recommended 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.
