12.3.1 Bead breaking tool with double joint
(on demand)
The bead breaking tool is equipped with a double joint
(Fig. 19) that allows, during the bead breaking phase,
to optimize the relative position between the vane and
the bead of the tyre inserting the joint between the vane
and the edge of the rim.
If the machine is utilized with rims that have protected
edges or depressed tyres and/or tyres with heavy thick-
ness, it's recommended to place the vane-joint so that
the hole (Fig. 19 pos. 2) can be utilized.
To change the position of the vane on the joint extract
the pin (Fig. 19 pos. 1) from the hole in which it is
inserted, turn the vane until the required hole corre-
sponds to the hole placed on the joint, then insert the
pin (Fig. 19 pos. 1) again into its new seat.
