Breaking The Upper Bead - Magneti Marelli TPMS CONNECT EVO Guía Rápida

Many bead breakers use a blade to break the bead loose from the wheel; with this
kind of equipment, position the wheel so the sensor is at 6 o'clock before beginning.
If the bead does not break loose at the first attempt, remember to insert the bead
breaker blade away from sensor body throughout the procedure. If you are using a
bead breaker with rollers, make sure the roller will not push the bead into the wheel
well or the bead might hit the sensor during rotation.
If you are using a blade-type bead breaker, make sure the blade is
well away from the sensor. Otherwise, the blade might push the tire
bead into the wheel and it might contact and damage the sensor.
If you are using a bead breaker with rollers, make sure the tire bead
is not pushed too deep into the wheel well as it is stretched around
the wheel rim, or it might damage the sensor

18.2. Breaking the upper bead

Lock the wheel onto the tire changing equipment - fitted with plastic shoes if
servicing a light alloy wheel - lubricate the bead and position the head so that the
sensor is just behind or under the head. Break the bead using the plastic-guarded lever
and place bead over head chisel. Slowly turn the wheel clockwise keeping distance
between bead and sensor steady.
