(Common procedure for Pax System with full width and clipé rest)
- Move the arm with the cylindrical roller B to the upper part of the wheel fig. 18
- Place the selector on 1. fig. 19
- Move the roller in position on the bead. fig. 20
- Using the lever pneumatic switch (G), press the roller onto the bead of the tyre. To
guarantee correct positioning of the roller, it is recommended to secure the arm (B)
with the handle (F).
- During bead breaking, apply liquid lubricant by spraying. fig. 20
- It is recommended to rotate the wheel a few turns with the roller pressing on the
bead in order to ease the tension on the bead.
- The réglette will be inserted in the space obtained between the bead and the edge of
the rim. fig.21
- Insert the réglette as shown in fig. 22, fig. 22a.
Note:
The réglette is inserted between the edge of the rim and the bead. A notch on the
réglette allows to insert the tip of the bead breaking lever.
WARNING
The same réglette can be used for more than one demounting. First check its condi-
tion. If the tang of the réglette shows signs of deterioration, replace with a new one.
There is a special way to insert the réglette. The part with the lever housing is to be
held towards the exterior of the wheel. During rotational movement in order to insert
the réglette, the tang must pass under the cylindrical roller.
- Lift the roller by acting on the pneumatic lever switch (G) and move it backwards.
- Insert the lever into the réglette housing, fig.22a.
- Lift the bead by pressing on the centre of the wheel, fig 22a.
WARNING
Make sure that the lever is well inserted under the bead before lifting the bead.
- After bead breaking, immediately remove the réglette from the tyre fig. 23
WARNING
Be careful not to drop the réglette inside the tyre. You might leave it inside the tyre
during the next mounting.
WARNING
Be very careful to avoid contact between the bead of the tyre and the pressure trans-
ducer, and between the pressure transducer and the demounting/mounting
tools. Contacts with unusual stress may damage the sensors or create sealing defects
between the valve and the rim.
