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)/

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.
