to lift the bead to the exterior of the rim
(Fig.29).
· Operate the control for rotating the
turntable to bring the bead out of the rim
(Fig.30).
· When demounting is complete, move the
tool to the right and away from the rim,
and activate the demounting lever for the
opposite direction. The rim returns to its
original position and the tool will return to
the horizontal position.
· With tyres with an inner tube, place the
wheel on the floor and pull the rim back to
create the space necessary for removal.
(fig. 31).
REAR BEAD DEMOUNTING:
· Use the S.T.S. control to move the tool
unit to the other side of the wheel.
· Now turn the turntable.
· Bring the bead breaker disc near the
bead and start to push it outward.
Be careful that the bead does not tip on
the rim edge while it is being pushed out.
If necessary, as soon as the disc has passed
the rim edge, lower the turntable a few
cm. This will decrease the bead tension
and make it easier to demount the wheel.
(fig. 32).
· NOTE
For some types of rims, such as with a
double well or skidder, a demounting tool
and a manual lever must be used.
Using the search control, (control 4, fig.

bead is hooked by the tool. Return the tool
to a horizontal position. At this point, turn
