your specific application.
HAZARD
RISK OF BURSTING
Air Tank: The air tank on your Air Compressor is designed and may be UM coded
(for units with air tanks greater than 6 inch diameter) according to ASME Section VIII,
Div. 1 rules. All pressure vessels should be inspected once every two years. To find
your state pressure vessels inspector, look under the Division of Labor and Industries
in the government section of a phone book .
The following conditions could lead to a weakening of the air tank, and result in a
violent air tank explosion:
WHAT CAN HAPPEN HOW TO PREVENT IT

GLOSSARY
ACCESSORIES
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
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
