HEIGHT OF CUT (FIG.44)
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 6mm(1/4in) under the head.
b.
Screw Y to 5.2mm (7/32in) to screw thread
tip.
Note: The difference between screw X and screw Y is
0.8mm (1/32in).
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 blade.
4.
Adjust the roll to the setting bar (G) with the two
locknuts(H)
holding setting bar screws in contact.
5.
Repeat for other end of bottom blade (bedknife).
TO SET HEIGHT OF CUT
Chose the range of height in which cutting is to be carried
out and then
adjust front roll only.
1.
Preset the height of cut setting bar (G)as follows:
a.
Screw X to the required height of cut under
the head.
b.
Screw Y is not used.
2.
At one end of the bottom blade (bedknife) lay
setting bar (G) on rear roll with screw head over
bottom blade (bedknife) lip.
3.
Adjust front roll to the setting bar by means of the
two front locknuts (J).
4.
Repeat for the other end of the bottom blade
(bedknife).
