air supply setup tips:
• 

if  the  air  hose  is  longer  than  25-feet, 
increase the air pressure to 100 psi to 
compensate for air flow restriction.

• 

For  consistent  air  flow,  use  air  hoses 
with an inside diameter of 

3

8

" or larger.

• 

to  eliminate  air  system  moisture  and 
maintain automatic lubrication, install a 
main or in-line filter water separator as 
far as possible from the air compressor, 
but  before  any  automatic  in-line  oiler.
