INSTRUCTION, USE AND
MAINTENANCE MANUAL
If the motor slows down or stops during tyre demount-
ing and mounting, make the following checks:
• Check that the bead has been lubricated.
• Check that the bead has been pushed into the groove.
• Check that the right side of the rim has been chosen
for demounting or mounting the tyre.
• Check that the supply pressure is not below 8 bar.
• Check that the rim groove is not off-centre.
There are rims on the market for which it is diffi-
cult to check the position of the groove with the tyre
mounted. A useful method for checking is to use the
bead-breaker rollers, pressing on the tyre sufficiently
to see the inside of the rim.
13.7 Mounting the tyre
To mount the tyre, proceed as follows:
1. Lubricate the tyre’s beads.
2. Position the tyre on the rim and lower the arm (after
it has been released with the relevant push button)
to position the mounting tool on the rim outside
edge, checking the inclination.
3. Position the lower rim edge on the left side of the
mounting tool and press the pedal to rotate clock-
wise.
4. Repeat the operation on the upper bead, taking care
first to position the valve insert at “5-6 o’clock”.
When mounting hard low-profile tyres, it may be useful
to use the upper bead-breaker roll to push the bead
into the groove (see
Fig. 35
).

pared to the rim-edge
(Disassembly)
1. Clamp the wheel by means of the clamping device
(preventively deflate the tyre completely and remove
the balancing counterweights on both sides of the
wheel).
2. Carry out tyre bead breaking with the standard
procedure.
3. Use the upper bead breaker roller to lubricate with
an approved lubricant the tyre bead, the lip, the
bead seat and the EDGE of the RIM.
4. Position the mounting/demounting arm (after it has
been release with the relevant push button) and use
the bead lifting lever to pull tyre’s bead upon the
mounting tool.
5. Raise the lower bead breaker roller to reduce the
tension of the tyre on the mounting tool.
6. Rotate the wheel in clockwise direction pushing the
pedal provided.
7. With the lever lift the lower bead onto the mounting
tool and rotate in clockwise direction in order to
complete demounting.
(Assembly)
1. Lubricate both tyre-beads with an approved lubri-
cant.
2. Lubricate the inner part of the mounting tool and
also the rim-edge.
3. Complete mounting procedure following the stand-
ard procedure.
