PRACTICAL HINTS, ADVICE
AND USEFUL INFORMATION
WARNING
To read before using the S 100 PL tyre
changer.
The following information is highly signifi-
cant as it facilitates the operator’s job and/
or helps clarify any doubts that might arise.
Practical Hints
• Upon demounting, over-lubrication and/or
an unusually shaped rim edge may cause the
tyre to slip on the rim, making demounting
difficult. First, try using the bead breaker
disc in an upward direction to raise the
tyre. Otherwise, to speed up the procedure
simply place the manual Help accessory
between the tyre and the edge of the rim.
This will help lifting the bead quickly off the
rim so that it can be demounted (fig. 12).
• Upon demounting, if the tool cannot
completely overturn the tyre bead to allow
demounting to start, the tyre bead may still
be, or just have been, inserted at 180° to
the demounting zone.
In this case, it is es-
sential to restore the ideal condition, with
the tyre bead inside the well of the rim
.
This operation can be assisted with any tool
you wish (clamp supplied with the machine,
pliers, bead presser or lever) (fig.12A).

• Upon demounting, if the tool cannot keep
the tyre bead engaged to allow demounting
to start, the tyre bead may still be inserted
on the underside. Try using the bead brea-
ker disc in an upward direction both to break
the tyre bead again and to help maintain a
grip on it (fig. 12B).
