The curved slots (4 places) for the contact drive input
shaft need to be elongated by 21.0 mm (0.83 in).

25. Make two copies of page 12 at 1:1 (100%) size (or
print at 100% size from the PDF of this manual), for
use as marking templates. A ruler image is included
on the page to verify that the copy is 1:1 scale.
26. Mark the elongation boundary (the dashed line) on
the tongue mount plates.

steel, to elongate the four curved slots . Check the
final edge against the template.
Notch Spring Brackets
The parallel arm spring brackets (where the bottom
of the hold-down springs attach) need to have a notch
cut in them (8 places) to allow spring clearance at the
limits of the arm movement now allowed by the longer
curved slots.
Refer to Figure 7 and Figure 20 on page 11
28. Make four copies of page 11 at 1:1 (100%) size (or
print at 100% size from the PDF of this manual), for
use as marking templates. A ruler image is included
