- Tilt the tower backwards by holding the
button in the "unlocked" position (on the
A 2005, keep the lever locked) (fig.13).
- Set the clamps to the open or closed
position (fig.14-14b).
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 mounting/demounting
device in the correct position against
the edge of the rim (fig.16).
IMPORTANT: when the handle is turned,
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 ver-
tical 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 or use
the lever guard provided.
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 auto-
matically 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 stop-
ped at any time by releasing the pedal.
To rotate in the opposite direction, simply
raise up the pedal.
TYRE MOUNTING
WARNING
Always check that the size of the tyre
is compatible with the size of the wheel
before proceeding with mounting.
- Before you start with tyre mounting
operations, apply a liberal amount of
tyre manufacturer approved rubber
lubricant to both beads (fig.19).
Lubricated beads require less force to
mount/seat and are protected against
torsional damage.
Make sure that the tyre is in good con-
dition without any signs of undue wear
or damage.
- Place the tyre over the wheel and tilt
the tower forward. Position the bottom
bead (fig.20) beneath the right hand side
of the mount/demount head. Press the
table top control pedal to turn the table
clockwise and mount the bead. Use the
drop centre by pressing the sidewall
opposite the head to reduce tensional
force on the bead as the wheel rotates
(fig.20).
- Once you have mounted the bottom
bead, repeat the same steps for the
upper bead (fig.21).
- Tilt the tower back, free the wheel and
take it off the tyre changer.
