BEDKNIFE REPLACEMENT
Bedknives that cannot be repaired by lapping or grind-
ing should be replaced. The bedknife is held to the
bedknife shoe by flat head screws. When replacing a
bedknife, the bedknife should be lightly ground to level
the cutting edge.
1. When a bedknife is installed, clean the backing
prior to installation.
2. Secure the installed bedknife by tightening the
mounting screws, starting with those at the center
and working out to the ends.
3. A new bedknife must be ground to assure straight-
ness and parallelism with the reel cylinder (see
Section 12D).
