HEIGHT OF CUT

It is important to set the rear roll parallel to the bottom
blade (bedknife) in order to achieve the
minimum height of cut setting for the three
ranges of height, in the three sets of
mounting housing (D) bolt holes. Positions
'A','B' &'C'.
Setting the minimum height with the mounting
housings (D) in position 'A' will allow
minimum height and parallelism to be
achieved in each of the other two positions
'B' & 'C'.
Once the range has been chosen the actual height
of cut is set by adjusting the front roll only
by carriage screws (F) and locknuts (J).
TO SET REAR ROLL
with a new bottom blade (bedknife)
1.
Set the height of cut setting bar (G)as follows:
a. Screw X to 12mm(15/32in) under the head.
b. Screw Y to 6.5mm (1/4in) to screw thread
tip.
Note: The difference between screw X and screw Y
is 5.5mm (7/32in).
2.
Set roll carriage mounting housing(D) bolts
into holes 'A'.
3.
Place the setting bar (G)as shown at one end
of the bottom blade with the screw head X over
the lip and screw thread Y tip against base of

4.
Adjust the roll to the setting bar (G) with the
two locknuts(H) holding setting bar screws

5.
Repeat for other end of bottom blade
(bedknife).

follows:
a. Screw X to the required height of cut under
the head.
b. Screw Y is not used.

The height of cut range for each set of holes
takes into account the requirement of the
cutting unit to float. Increasing the maximum
height of cut in any of the hole setting ranges
could restrict the ability of the cutting unit to
float.
