in the Description of Operation
paragraph in the Operation Section.
NOTE: Adjust the regulated
pressure under flow conditions
(while accessory is being used).
Decrease amount of air usage.

it is higher than the SCFM or pressure
supplied by your air compressor,
you need a larger compressor.
Check and replace if required.
Have checked by a Trained
Service Technician.
