Important: Always read and follow operating instructions.
Lower Bead Loosening
Keep the bead loosener system set up as for upper bead
loosener disk procedure: the lower bead loosener disk is
always aligned with the upper one, and it is already positioned
at
3-4 mm
from lower rim edge.
Lift the lower bead loosener disk until it touches the lower tire
bead using controls
13
for lifting and
12
for lowering.
Rotate wheel
clockwise
.
While spinning the wheel, push the lower bead loosener disk
up above the edge of the rim, then press and hold down the
“over-run”function button

As soon as enough space is available, carefully apply tire lube paste to both to the rim inner surface and to the
tire bead (fig. 2).
NOTE
: For a better view and control of the lower bead loosening, use the mirror mounted on the main frame.
While lossening the bead, just press on the bead and never on the side of the tire.
Match Mounting
Driving could be affected by vibrations caused by
deformations of the rim and/or tire. To optimize the
wheel-balancing, it is necessary to position the wheel
onto the Tire Changer again to bead loosen and lubricate
the rim and the tire, spinning the tire around the rim to a
proper position.
Both upper and lower disks make this process easier,
by gently holding the tire steady while the clamping
chuck spins the rim until the correct matching position is
reached.
