5.1) Adjusting the piston stroke for clip insertion
FIG. 16
3
The upper ring nut establishes the piston stroke when the clamp is advancing towards the rail during clip
installation. To adjust, proceed as follows:
Turn the upper ring nut of one piston so as to bring the reference line to an intermediate position on the
graduated scale (Ref. to Fig. 16).
The reference line corresponds with the end of the ring nut.
Carry out a clip insertion (see § 4.9.1) and check the position of the clip.
The "installation" position is diff erent depending on the type of clip, normally they should be at a safe distance
(x) from the edge of the spacer insulator (Ref. to Fig. 17), except where stated otherwise.
If this is not the case, to increase the distance (X) during insertion, unscrew the upper ring nut towards zero,
then re-try insertion. Conversely to reduce the distance (X), tighten the upper ring nut towards the number
three. Several attempts may be necessary to obtain the exact clip position, using the graduated scale to make
fi ne and exact adjustments.
Having found the exact adjustment for one piston, position the ring nut of the other piston at the same value
on the graduated scale.
INSTALLATION POSITION
The lower ring nut establishes the piston stroke when the clamp is returning towards the starting position.
To adjust, proceed as follows;
Tighten the lower ring nut of one piston towards the number three to reduce the clamp opening (Ref. to Fig.16).
Unscrew the lower ring nut of one piston towards zero to increase the clamp opening (Ref. to Fig. 16).
