Operation

Operating the die grinder

 

This Die Grinder is designed to operate on 90 PSIG. Lower 
pressure (below 90 PSIG) will reduce performance of 
the tool. Higher air pressure (over 90 PSIG) raises the 
performance of the tool beyond its rated capacity and 
could cause serious damage to the tool and the user.
