Tubeless And Supersingle Wheels; Bead Breaking - SICE S 560 Manual De Instrucciones

ENGLISH • Instructions manual
LIGHT-ALLOY RIM LOCKING
The GL clamps - especially designed for operating on light
alloy rims without damaging them - is available upon
request. The GL clamps are to be inserted (bayonet-like
mounting) into the clamp support of the self-centering
chuck (see fig. E/7).
Tighten screw 1, Fig. E/7 by hand to lock the GL clamp.
The clamps are supplied with three different types of plastic
insert (2, Fig. E/7), which must be used to suit the thick-
ness of the rim flange.
Lock the rim as illustrated in fig. E/8.
The specially-made PL alloy-rim pliers are also available.
CAUTION:
The spindle may "slip" during the various operating phases when the rims are locked on the central
hole (especially with alloy wheels where GL clamps are used). This can be avoided by fitting a bolt
into one of the wheel fixing holes (1, Fig. E/9) and locking it in place with the relative nut.
As the bolt is turned, it will rest on the clamp, carrying the rim with it and preventing this from
slipping.
CLAMP EXTENSIONS
For rims with diameters over 46" without central hole flange, the wheel can be clamped with the
PA extensions (optional).
Insert the clamp extension into the clamp support of the self-centering chuck arm (bayonet mount-
ing) and lock it with the wing nut (see fig. E/10).

BEAD BREAKING

1) Lock the wheel on the self-centering chuck, as previously described, and ensure that the tyre is deflated.
2) Take the mobile control unit to work position C.
3) Lower the tool-holder arm (14, fig. F) into is working position and allow it to lock.
DANGER!
Always check to be certain that the arm is corrected
hooked to the carriage.
4) Operating from the mobile control centre, manoeuvre the wheel until the outside
of the rim skims the bead-breaker disk (fig. F).
DANGER!
The bead breaker disk must NOT be pressed against the
rim but against the tyre bead.
5) Rotate the wheel and at the same time, advance the bead-breaker plate with small
forward movements following the profile of the rim, with the plate.
6) Continue until the first bead is fully detached.
