Pressure  regulator:    A  pressure  regulator  is  required  to 
control  the  operating  pressure  of  the  nailer  between 
180PSI and 330PSI.

  Always  use  air  supply  hoses  with  a 

minimum working pressure rating equal to or greater than 
the pressure from the power source, or 600PSI, whichever 
is greater. Use 1/4 inch air hose for runs up to 50 feet. Use 
3/8 inch air hose for 50 feet, run or longer.

MINIMUM COMPONENTS 

REQUIRED FOR HOOKUP

Air  compressor:

  The  air  compressor  must  be  able  to 

maintain a minimum of 180PSI when the nailer is being 
used. An inadequate air supply can cause a loss of power 
and inconsistent driving.
