arm (ref.No. 74).
3. In order to adjust the pair of side bearings (ref.No. 78), act on the dowel
(ref.No. 80) so that the bearings rest on the blade and, then, loose it as
much as it is necessary to let the blade slide, by leaving a backlash of
about 0.04 mm.
4. When the adjustment has been completed, tighten its nut.

for which the bearings of the blade guide have been adjusted. In case of
thicker blades, if is necessary to adjust the blade guide once again as above
