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.

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.

Accessories for this unit are available at the store the unit was purchased.

SPECIFICATIONS

GLOSSARY

DUTY CYCLE

ACCESSORIES

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.
