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.

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.
