CHAPTER 5
– 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 maintain pressure level at the pressure regulator in compliance
with OSHA or the pertinent regulatory entity.
5.1
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 moves quickly and powerfully.
Anything within its range of action can be pressed or crushed.
•
Check that the tire is deflated. If not, deflate it.
•
Close the turntable clamps completely.
Bead breaking with the clamps in open position can be extremely dangerous for
the operator’s hands.
NEVER touch the side of the tire during bead breaking operation
•
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 circumference if the rim and
from both sides until the bead is completely detached from the rim.
