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.

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.
