BEAD BREAKING
The bead breaker arm of the machine is equipped with a patented system which allows
to obtain two different working inclinations between the blade and the wheel.
-Fully close the turntable clamps (fig. 11) acting on pedal 3 fig. 9.
-Remove the weights from the rim.
-Fully deate the tyre, removing the valve
- Adjust the rim rest depending on wheel diameter
-Adjust the inclination of the blade according to the wheel width by means of the pin in order to
obtain a better inclination between the blade and the tyre: in position 1 in g.12 for low width tyres,
in position 2 for high width tyres
-Place the wheel as shown in g. 13 and take the blade near the bead, keeping the necessary safety
distance between the rim and the bead breaker blade, so that the latter works on the tyre and not
on the rim.
-Press pedal 1 (g 9) to activate the bead breaker and free the bead from the rim.
Release the pedal. Pressing the bead breaker pedal (1 g. 9) the arm moves (13 g.9) and it may
be dangerous (crushing danger); pay the utmost attention during bead breaking.
Repeat this operation on the other side of the wheel.
It may be necessary to break the bead at several points to free it completely.
WHEEL CLAMPING
-Check if there are any weights left on the rim; if so, remove them.
-Thoroughly lubricate the sides of the tyre around the entire circumference of the lower and upper
bead to facilitate the demounting and avoid damaging the beads (g.13).
-Tilt the tower backwards.
-Depending on the diameter of the rim, close the four clamps if the rim is to be clamped from inside
or open them if the rim is to be clamped from outside. Place the wheel on the turntable, push it lightly
down and act on the control pedal to lock the wheel in its proper position (g. 13).
Acting on the turntable pedal (3 g.9) closes the clamps and may be dangerous (danger of hand
crushing). During rim clamping, do not keep the hands under the tyre.
