• Keeping the lever pressed, lift the wheel until the
edge of the rim is 5 mm distant from the hook tool.
• Rotate the wheel clockwise until the bead has com-
pletely gone out.
• Once the external bead has been removed, move roll
holder arm away from the wheel, unhook it and lift
it bringing it in “off-work” position (
Fig. 18 pos. 1
);
use the handle control to position the tool holder arm
on the inner side of the wheel then place it in “work
position” again (
Fig. 17 pos. 1
) and secure with the
safety pin provided.
PAY ATTENTION WHEN REPOSI-
TIONING THE ROLL HOLDER ARM

ARM IS CORRECTLY LOCKED TO
THE SHIFTING BEAM.

TYRES IT IS ADVISABLE TO PAY
CAREFUL ATTENTION BEFORE
COMPLETING THE OPERATION.
