WARNING! Position the blade as to operate the bead
of the tyre and not of the rim.
4) Push the blade (14, Fig. D) into the tyre by depressing pedal (3,
Fig. D).
Repeat this process at different points around the tyre and on both sides
until the beads are completely loosened.
WARNING: During bead breaking, care must be taken
not to deform the tyre too much as this may damage
it.
WARNING: To avoid the risk of damage to the valve
and the pressure sensor (if installed), only break the
bead with the valve and sensor at 90° to the bead
breaker pressure point (at 12 o'clock and 6 o'clock).
Before proceeding with the bead breaking procedure,
it is essential to identify the type of tyre being
worked on (especially when working on RUN FLAT,
LOW PROFILE or UHP tyres).
The bead breaker arm of the S 45 TL has 2 working positions (see
Fig. G/4 and G/5):
- the position shown in Fig. G/4 is recommended for working on
wheels with rims up to 10" wide;
- the position shown in Fig. G/5 is recommended for working on
wheels with rims more than 10" wide;
The angle of incidence of the bead breaker blade varies depending on
the position chosen.
To change from one working position to the other, proceed as follows:
- extract the peg (1).
- turn the blade by hand until the hole on the hub is in the other posi-
tion;
- fit the peg (1) in the new position.
N.B.: The blade angle can also be increased by moving the rod to the
right, for easier bead breaking on small-diameter rims
WARNING: NEVER break the bead of rims less than
6" wide with the bead breaker arm in the "+10"
working position.
The stroke limiter (see Fig. F3) is required for bead breaking on RUN FLAT,
LOW PROFILE and UHP tyres.
The device limits the "closure" of the bead breaker by different amounts
depending on the position of the pin (1, Fig. F3):
- setting "0" : no limitations
- settings 6"-7" ; 8 -9" ; 10"-11" : indicate the rim width for which the bead
breaker closure is set.
Check the rim width and then place the pin in the correct hole: the stroke
limiter will enable bead breaking and prevent the blade from penetrating the
