3. Hook the screw head on cutting edge of bedknife and
rest rear end of bar on rear roller (Figure 19).
4. Rotate the adjusting screw until the front roller contacts
the gauge bar (Figure 19). Adjust both ends of roller
until entire roller is parallel to the bedknife.

3. Nut
Important: When set properly, the rear and front
rollers will contact the gauge bar and the screw
will be snug against the bedknife. This ensures
that the height-of-cut is identical at both ends of
the bedknife.
5. Tighten nuts to secure adjustment. Do not overtighten
nut. Tighten enough to remove play from washer.
