IN CASE OF USE OF RIMS WITHOUT CENTRAL
HOLE, IT’S NECESSARY TO USE THE PROPER
FIXTURE (AVAILABLE ON DEMAND).
To lock a rim proceed as follows:
1. Dowel the wheel (Fig. 22 ref. 1) on the locking platform and
check that the dragging pin (Fig. 22 ref. 2) enter in a hole placed
on the rim hub.

2. Place the wheel on the mandrel and lock it with the locking
device.
3. Lift the pedal (Fig. 19 ref. 1) upwards in order to lower the lifting
plate.
4. After all tire demounting and mounting operations have been
performed, unlock the wheel by removing the locking device.
5. Lift the lifting plate by pressing again the pedal downwards
(Fig. 19 ref. 1).
6. Place the wheel on the lifting plate (see Fig. 20).
7. Move the pedal again (Fig. 20 ref. 1) upwards to make the plate
lower and bring back the wheel to the ground keeping a hand
on it (see Fig. 20).
