- Set the swing arm and vertical slide with the lever M (Fig. 5)
so that the lower part touches the edge of the rim.
- Close lever M to lock the vertical slide C. Close lever M and
the vertical slide will automatically move away from the rim
by approx. 2 mm.
To adjust the horizontal slide position, use the hand-wheel N.

ing slide and the tyre bead (Fig. 8)
When working with alloy wheels or wheels with delicate
paintwork, you are advised to remove the bead lifting tool
before proceeding with the demounting.

repeatedly on pedal F.
- Rotate the wheel through one complete turn, pressing down
with the hands on the side of the tyre opposite to the vertical
slide, so that the bead is positioned in the central rim groove.

- Once demounting is complete, move the arm outwards to
release the tyre.
WARNING
Always check that the size of the tyre is compatible with
the size of the wheel before proceeding with mounting.

signs of damage.

to the work position.
Position the lower bead under the front part of the vertical
slide. Press the pedal to turn the table top clockwise and

the right-hand wall of the tyre to reduce the torsional stress
on the bead during rotation (Fig. 10).
