How do I change the drive rolls on the Miller 350P?

The drive assembly comes equipped with factory-installed .035/.045 combination drive rolls. To change them, loosen the securing screw and slide the inlet wire guide as close to the drive rolls as possible without touching, then tighten the screw. Install the correct drive roll for the wire size and type you are using, then turn the drive roll securing nut one click to secure it. Make sure all 4 drive rolls are installed correctly. (Page 31)
