DEMOUNTING
AGRICULTURAL
WHEELS
Clamp the wheel on the turntable.
Operate the control lever to lift the wheel
so that the rear edge of the rim just touches
the bead breaker disc (Fig. 24).

BEAD BREAKING

Once the tyre is deflated, continuously ad-
vance the turntable in small steps with the
relative control.
To make the bead breaking operation
quicker, operate the control that adjusts
the rotational speed.
NB: When working with radial tyres with
delicate side walls or rims with a very
high edge, insert the bead breaker deeply
between the rim edge and the bead, as far
as the base of the shoulder of the rim.
When the bead breaking is complete, lu-
bricate the bead and the shoulder of the
rim using the specific grease or a soapy
solution, keeping the wheel in movement.
Operate the S.T.S control. + Function for
switching tool unit from one side of the
wheel to the other, with rotation.
NB: With particularly heavy wheels, for safe-
ty reasons, the tool unit should be moved
manually from one side of the wheel to the
other. Do not use the second speed setting.
Repeat the same operations for front bead
breaking.
DEMOUNTING THE FRONT BEAD:
· Press the "tool plane" button to position
the wheel correctly relative to the de-
mounting tool. (fig. 25).
