- Now operate pedal
-Here again, it might be helpful to move the bead breaker disc upwards on the lower
part of the tyre.
During the tyre dismounting phase, an over-
lubrication and/or an unusual shape of rim
edge may cause the tyre to slip on the rim thus
making this operation extremely complicated.
To solve the problem, try moving the bead bre-
aker disc upwards to push and raise the tyre.
Alternatively, to further speed up the activity
lifting the bead quickly off the rim, simply place
the manual help lever between tyre and rim.
During the early demounting phase, the tyre
bead may still be inserted at 180° from the
mounting tool area thus making the tool unable
to completely overturn the tyre. In this case,
it is necessary to keep the bead pressed in
the channel using the supplied bead pressing
device positioned at 6.00 o'clock (also the
optional bead pressing clamp can be used).
This advise should be utilized when handling
particularly low profiled or tough tyres such
as the Run-Flat.
