4.6.2) SIMULTANEOUS EXTRACTION OF 2 FASTCLIPS
Make sure the the locking knob (29) of the wheel is released (see § 4.2).
An "Extraction operation" means (see § 4.4):
1 - Moving from "installation position" to "parking position".
2 - Moving from "installation position" to "insulator change position".
3 - In exceptional cases, the complete extraction of the Fastclip.
– Push the machine to the Fastclips on which operations are to be performed (see § 4.2).
IMPORTANT: when performing the fi rst extraction operation, the correct stroke of the
rams will have to be established so the Fastclips are positioned precisely (see § 5.2).
– Make sure the clamps are open by pulling the clamp control lever (07) to the left "EXTRACT"
position.
– Pull and turn knob (36) to release the extraction hook (44) which will position horizon-
tally (see Fig. 15).
– Fully lower the machine and position the jaws (43) so these rest on the top of the
support shoulders (see Fig. 12a).
– Move the extraction hook (44) fully forward by pulling the control lever (07) to the right
"INSERT" position (see fi g. 12a).
– After positioning on the Fastclip, pull the control lever (07) to the left to "EXTRACT"
position and keep it pressed until clamp movement stops: the hooks (44) will gra-
dually move back, with consequent removal of both the Fastclips (see Fig. 12b).
After removal, pull the control lever (07) to the right to "INSERT" position until the ma-
chine is released.
– Lift the machine, move to the next Fastclips and repeat the above operations.
– Having completed the operation, return the hooks (44) to the vertical position and block
these with knobs (36).
NOTE: Because the two clamps are independent, their movement may be different, with
diff erent reaction times.
Movement of one of the clamps is schematically shown in the illustrations; the other will have an identical and opposite movement.

5.1) Adjusting ram stroke for the insertion operations
The upper ring nut establishes the stroke of the ram during forward movement of the clamp
towards the rail during Fastclip installation; to adjust this, proceed as follows:
– Turn the upper ring nut of a ram until the reference line is in the intermediate position
of the graduated scale, POS. 2 (see Fig. 14).
– Perform an insertion operation (see § 4.6.1) and check the position of the Fastclip.
When in installation position, the Fastclip must normally be at 1- 3 mm from the edge
of the side post insulator (see Fig. 13), unless otherwise indicated.
If this is not the case, turn the upper ring nut clockwise to increase the stroke of the
ram or anticlockwise to decrease it, then try another insertion: several attempts may
be necessary to obtain the exact position of the Fastclip. Use the graduated scale for
fi ne and precise adjustment.
– Once exact adjustment has been made on a ram, position the ring nut of the other ram
on the same graduated scale value.
INSTALLATION
POSITION
The lower ring nut establishes ram stroke during clamp opening, after installation of the Fastclip;
to avoid any wasteful empty stroke of the ram, we suggest regulating the stroke until the refer-
ence line is in the intermediate position of the graduated scale, POS. 2, so the clamp opens just
enough to release the machine from the Fastclips and allow placement on to the next Fastclips.
If necessary, proceed to make an even fi ner adjustment.
Once exact adjustment has been made on a ram, position the ring nut of the other ram on the
same graduated scale value.
