GLOSSARY
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 applicable Underwriters Laboratories Standards for Safety.
English
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 3045 minutes in any given hour.

Regulator is not adjusted correctly for accessory being
used
It is normal for some pressure drop to occur when an accessory is used, adjust the regulator as instructed in Regulator
under Features if pressure drop is excessive.
NOTE: Adjust the regulated pressure under flow conditions
while accessory is being used.
8 Prolonged excessive use of air Decrease amount of air usage.
9 Compressor is not large enough for accessory Check the accessory air requirement. If it is higher than
the CFM or pressure supplied by your air compressor, a
larger compressor is needed to operate accessory.
