Extraordinary" Mounting Rocedure; Correct Procedure For Demounting/Mounting Run Flat Tyres - SATA AE1032H Manual De Instrucciones

10. "EXTRAORDINARY" MOUNTING ROCEDURE

- A variation of the mounting procedure explained above may be adopted in case of rims with very small or non-existent
drop centre (fig. 11 -B). In these exceptional cases, the mounting procedure can be facilitated byusingavariantofthenormal
procedure.
- The first bead is mounted in the usual way. To mount the second bead, position the movable tool as when approaching
for demounting (fig. 32).
- This reduces the stresses, leaving more space for the tyre. The following opera¬tions, illustrated from fig. 28 on, remain
unchanged.
