BEAD BREAKING

When the tyre is deflated, turn the turntable in continuation, moving it a little at a time

using the specific control�

To make the bead breaking operation quicker, operate the control that adjusts the

rotational speed�

N�B� In the case of radial tyres with a delicate side or rims with a very high edge,

move the bead breaker to a depth between the rim edge and the bead, as far as the

base of the shoulder of the rim�

When the bead breaking is complete, lubricate the bead and the shoulder of the rim

using the specific grease or a soapy solution, keeping the wheel in movement�

Use the S�T�S� + function to move the tool unit from the other side of the wheel, turned

(fig� 24)�

N�B� If the wheel is very heavy, the tool unit should be moved manually from the other

side, not using the second speed for safety reasons�

Repeat the same operations for rear bead breaking�

Return the tool holder arm to the front part using the S�T�S� command�
