tool receives sufficient, unobstructed 

airflow (CFM) and increase the 

pressure (PSI) output of the regulator 

up to the maximum air pressure 

rating of this tool.

and accessOrY failure, 

resulting in injurY: 

do not exceed the tool’s maximum 

air pressure rating.

 

If the tool still does not have sufficient 

force at maximum pressure and 

sufficient airflow, then a larger tool 

may be required.

discharge any residual air pressure in 

the tool, and release the trigger after
