GLOSSARY
Become familiar with these terms before operating the unit.
CFM: Cubic feet per minute.
SCFM: Standard cubic feet per minute; a unit of measure of air delivery.
PSIG: Pounds per square inch gauge; 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 applicable Underwriters Laboratories
Standards for Safety.
Cut-In Pressure: While the motor is off, air tank pressure drops as you
continue to use your accessory. 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.
DUTY CYCLE
Air compressors should be operated on not more than a 50% duty cycle. This
means an air compressor that pumps air more than 50% of one hour is
considered misuse, because the air compressor is undersized for the required
air demand. Maximum compressor pumping time per hour is 30 minutes.
Accessories for this unit are available at the store the unit was purchased.

A circuit breaker is preferred. Use only a fuse or circuit breaker that is the same
rating as the branch circuit the air compressor is operated on. 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.
