4.5.2) Adjusting the height of the front of the machine
After making the adjustments described in § 4.5.1
proceed to adjust the machine horizontally as follows:
– Fully lower the machine so it is resting on the
support shoulders.
– Line up the side of the machine so that the
clamp unit is parallel with the upper surface of
the railhead. If this is not the case, adjust knob
(47) on the carriage (Ref. to Fig. 9).
To lift the machine turn knob (47) anti-clocwise.
To lower the machine turn it clockwise.
The measuring scale will facilitate adjustment
by precisely defi ning the correct position of the
machine.
Note: It may be easier to use the knob (47) with the clamp unit partially disconnected from the
carriage by the knob (48)
4.5.3) Stable rest of both the contrast jaws
Both contrast jaws (43) must be supported in the same way on the top of the support
shoulders (see Fig. 8). If this is not the case, after making the adjustments described in
§ 4.5.1 and § 4.5.2 proceed to adjust the machine vertically by means of the support wheel (41):
– Fully lower the machine so it is resting on the support shoulders.
– Loosen handle (40).
– Lower or raise the rod (39) to change the vertical angle of the machine and achieve correct
alignment.
– After making adjustments, fully retighten handle (40).

If this is not the case, turn the lower ring nut anticlockwise to increase the ram stroke
or clockwise to reduce it, then try another extraction; several attempts may be neces sary
to achieve exact Fastclip position. Use the graduated scale for fine and precise
adjustment.
47 – Once exact adjustment has been made on a ram, position the ring nut of the other ram
on the same graduated scale value.

5.2.2) "Insulator change position" of the Fastclips:
Follow the instructions at § 5.2.1 being careful to regulate the lower ring nut so as to increase
ram stroke, thereby favouring greater Fastclip return movement.
5.2.3) "Complete extraction" of the Fastclips from shoulders;
For all the operating stages described so far, the spacers (37) must be in the position shown
in Fig. 17a, for total extraction of the Fastclips only. Ram overrun will be necessary. This can be
obtained in the following way:
– Move the clamps fully forward by pulling the control lever (07) to the right to "INSERT"
position.
– Lift the spacers (37) (see Fig. 17a), turn them by 90° (see Fig. 17b) and move them
back down (see Fig. 17c) so the long slot fi ts into the stop; this will ensure complete
exit of the Fastclip.
