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

continuously. 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.
