IMPORTANT: During the bead breaking operation, you are advised to keep the table
top closed (locking clamp towards center) (A fig.11).
- Press the pedal 10 (fig.11) to operate the bead breaker and detach the bead from the rim.
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.
After detaching the beads, remove the old balancing weights.
- 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 (fig.12).
- Tilt the tower backwards by holding the button in the "locked" position (on the A 2005,
keep the lever locked) (fig.13).
- Set the clamps to the open or closed position (fig.14). For A 2025 and A 2030 see fig.14b.
Place the wheel on the table top (with the narrow part of the rim structure facing upwards),
push lightly downwards and use the control pedal to lock the wheel in position (fig.13).
- Tilt the tower forward again (fig.15). Release the locking button (release the lever on the
A 2005) to free both the vertical slide and the swing arm (fig.15a) and to set the mount-
ing/demounting device in the correct position against the edge of the rim (fig.16).
IMPORTANT: when the button is pressed (or the lever turned anti-clockwise on the A
2005), this will simultaneously lock both the vertical slide and the swing arm, with the
mounting/demounting vertical slide moving slightly up and away from the edge of the
rim (fig.16a).
This space between the rim and the vertical slide will be maintained for as long as the
button is in the locking position.
The operator can tilt the tower freely (eg. when demounting wheels of the same size)
without repositioning the vertical slide.
- Insert and position the bead lifting tool on the mounting vertical slide (fig.17).
When working with alloy wheels or wheels with delicate paintwork, you are advised to
remove the bead lifting tool before proceeding with the demounting.
WARNING
Grip the bead lifting tool firmly during use.
- Raise the upper bead to above the rear part of the demounting vertical slide (fig.17a)
and force part of the upper bead into the rim groove by pushing down on the side wall
of the tyre nearest to the operator.
- Press the pedal to turn the table top clockwise. The upper bead will automatically be
guided up and over the rim (fig.18).
Repeat the last three points to detach the lower bead.
- Tilt the tower backwards.
NOTE: If the tyre has an inner tube, after detaching the upper bead, tilt the tower back
and remove the inner tube before proceeding to demount the lower bead.
The rotation of the table top can be stopped at any time by releasing the pedal.
To rotate in the opposite direction, simply raise up the pedal.
