OPERATION
Demounting
CAUTION
For all tyre mounting/demounting proce-
dures not specifically described, refer to
the tyre changer use and maintenance
manual.
The Helper has been designed to simplify
demounting and mounting light alloy rims
and especially stiff low-profile tyres. Pro-
ceed as follows to get the best performance
from these accessories.
Demounting:
- For particularly stiff tyres with beads that
tend to slip back into place, use the rim
clamping cone A (fig. 6):
After breaking the bead of the wheel, place it
on the turntable and clamp it on the outside.
Fit the rim clamping cone in the specific seat
in the articulated joint of the arms Fig. 6,
align the cone with the hole in the centre of
the rim and press the down lever until the
sliding clamps have been inserted between
the rim and the tyre (Fig. 6.1), then press
the pedal to clamp the wheel.
