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:

For proper operation of your air compressor, it

is recommended that a 50% duty cycle be maintained; that
is, the air compressor should not run more that 5 minutes in
any 10 minute period.
