3- Adjust and lock the head and then put the vertical post into a non-working position.
4- Replacing the valve by correctly using a suitable tool is always recommended.
5- Thoroughly lubricate the entire inner surface of the rim (see Fig. P/1) and the tyre
beads both outside and inside up to a depth of at least 30 mm; also lubricate the entire
tyre outside (see Fig. P/2).
6- Put the valve in 7 o'clock position.
7- Place the tyre (by tilting it on the rim) so that the mounting head can be brought to
a working position.
8- Bring the mounting head to a working position.
9- Tilt the tyre so that the bead is placed under the mounting head in the 12 o'clock posi-
tion, press it down manually at 4 o'clock and start turning the turntable until the first bead
has been completely mounted (see Fig. P/3).
WARNING: In all phases in which the turntable must be turned,
the rim and the tyre must move together to avoid damaging
the valve with the sensor when crossing the traction points.
MOUNTING THE SECOND BEAD
1- Place the valve at approximately 5 o'clock.
2- Place the PT arm in a working position with the bead breaker disc on its end stroke.
3- Fit the extra fixed arm (BPT) on the PT.
4- Adjust the position of the bead pressing disc according to the rim diameter.
5- Using the knob, adjust the distance between the disc and the head (see Fig. Q/1); this
distance must be reduced to a minimum.
6- Turn the rotating arm of the PT anticlockwise until it is next to the fixed arm.
7- Place the edge guard at approximately 4 o'clock or in any case in line with the traction
point.
8- Lower the PT arms until the tyre bead is placed at the same height as the well (see
Fig. Q/2).
9- Visually check that the traction point is in line with the edge guard. If it is not, turn
the turntable until it is in line.
10- Start turning the turntable and at the same time manually accompany the moving arm
as it rotates (see Fig. Q/3).
WARNING: During this phase, check that the bead section between the fixed and the mov-
ing disc is always inside the rim well (see Fig. Q/3). If this is not the case, repeat the
operation from the beginning and increase the initial pressure.
N.B. Always check that the traction point remains above the edge guard.
