Since there can be variations in the mounting sur-
Relief Angle
face of the bedbar, a new bedknife will not be perfectly
flat after it is installed. It is therefore necessary to back-
lap or grind a new bedknife after installing it to the bed-
bar. Follow the existing angle that was ground into the
bedknife and grind only enough to make sure the top
surface is true.

Regrinding Bedknife
Remove bedbar assembly from cutting unit before at-
tempting to regrind a used bedknife (see Bedbar Re-
moval).
NOTE: When grinding, be careful to not overheat the
bedknife. Remove small amounts of material with each
pass of the grinder.
NOTE: If the height of cut is 1/2 inch (13mm) or lower
on the cutting unit, the front angle can be increased to
30
o for improved performance.
