feed roll grooves.
7. Adjust the pressure of the feed rolls with the pressure adjustment wheels. The pressure is the same for both feed
roll pairs.
The graduated scales on the pressure handle indicate the pressure applied to the feed rolls. Adjust the pressure of the
feed rolls according to the table below.
