LIGHT-ALLOY RIM LOCKING
The JAR-2 clamps - especially designed for operating
on light alloy rims without damaging them - is available
upon request. The JAR-2 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 JAR-2
clamp.
The clamps are supplied with three different types of
plastic insert (
2, Fig. E/7 ), which must be used to suit the thickness of the rim flange.
Lock the rim as illustrated in
fig. E/8
.
The specially-made SE-2R 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 JAR-2 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 SE-2 extensions (optional).
Insert the clamp extension into the clamp support of the self-centering chuck arm (bayonet
mounting) and lock it with the wing nut (
see fig. E/10
).

12.2 TUBELESS AND SUPERSINGLE WHEELS
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.
