protection and the spindle fl ange production must be used.
For the wider wheel, the longer driving pin can be supplied

To mount/demount the tire without a central hole, the
universal adapter should be ordered.

Breaking The Bead
Bead breaking must be done with the utmost care and
attention. When the bead breaker pedal is operated the bead
breaker disks moves powerfully. Anything within its range of
action can be in danger of being crushed.
During bead breaking operations NEVER touch the side of the
tire by hands.
Chains, bracelets, loose clothing or foreign objects in the
vicinity of the moving parts can represent a danger for the
operator.
To break the upper bead of the tire, do as follows:
• Bring the lower breaker disc (T) out of working
position.
• Set the selector (A) to UNLOCKING position.
• Bring the upper bead breaker disk (S) within 1/8”
- 1/4” of the rim edge by operating the levers (B)
and (D).
• Set the selector (A) to LOCKING position.
• Make sure to rotate the valve at 2 o’clock position
so that the valve cannot be damaged during the
breaking procedures.
