warnings it provides.
The operation of the tire changer is divided into three parts:
1). Breaking the bead
2). Demounting the tire
3). Mounting the tire;
Warning: before carrying out any operation, deflate the tire and take off all the wheel
balancing weights.
1). Breaking the bead
Warning: when the bead breaker pedal is operated, anything within the action range
of bead breaker arm can be in the danger of being crushed.
Check that tire is deflated, if not, deflate it.
Close the turntable clamps completely.
Warning: bead breaker with the clamps in the open position can be extremely
dangerous for operator's hands; during the bead breaking operations never touch the
side of the tire.
Position the wheel against the rubber stop on the right side of the tire changer.
Position the bead breaking blade against the tire bead at a distance of about 1 cm
from the rim. Pay attention to the blade, which must be correctly onto the tire not onto
the rim.
Press down the pedal (2) to activate the bead breaker and release it when the blade
has reached to 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 of
the rim and from both sides until the bead is completely detached from the rim.
