1. Select the die set required for the
operation to be performed.
2. Place spacers (#50), dies and
retaining nuts (#52) onto the driving
and driven shafts (#53 and #47).
Tighten the retaining nuts with wrench
(#59).
NOTE:
Some die sets require two spacers on
each shaft.
3. Adjust the position of the upper
die according to thickness of the
workpiece by using the adjusting
handle (#60).
4. Adjust the horizontal position of the
upper die by rotating the adjusting nut
(#27).
5. Adjust the stop gauge (#10 and
#15) or the stop plate (#14) to the
required size. The required size is
the distance the form will be form the
edge of the metal. Use the stop gauge
for sheet and use the stop plate for
cylinders. The stop gauge can be
finely adjusted using the thumb nuts
(#13).
6. Insert metal between dies and
slowly rotate the crank arm (#9).
Check the workpiece. It may be
necessary to fine tune the adjustments
made in steps 3 and 4. Repact steps
