CHAPTER 4 – OPERATION
Do not use the machine until you have read
and understood the entire manual and the
warning provided. Before carrying out any
operation, deflate the tire and take off all the
wheel balancing weights.
The operation of the tire changer is divided into three parts:
a) BREAKING THE BEAD b) REMOVING THE TIRE c) MOUNTING
THE TIRE
It is advised to equip the tire changer with
the pressure regulator.
4.1 BREAKING THE BEAD
Bead breaking must be done with the utmost
care and attention. When the bead breaker
pedal is operated the bead breaker arm mo-
ves quickly and powerfully.Anything within
its arrange of action can be in danger of be-
ing crushed.
· Check that the tire is deflated. If not, deflate it.
· Close the turntable clamps completely.
Bead breaking with the clamps in open posi-
tion can be extremely dangerous for opera-
tor's hands. During bead breaking opera-
tions NEVER touch the side of the tire.
· Position the wheel against the rubber stops on the right side of the
tire changer (S).
· Position the bead breaker (R) against the tire bead at a distance of
about 1 cm from the rim (fig. 8). Pay attention to the blade, which
must operate correctly onto the tire and not onto the rim.
· Press down the pedal (U) to activate the bead breaker and release it
when the blade has reached the end of its travel or in any case when
the bead is broken.
· Rotate the tire slightly and repeat the operation around the entire cir-
cumference if the rim and from both sides until the bead is completely
detached from the rim
