4.6.3 Fitting

Tubeless tyre fitting is normally done with the disc tool. If the wheel is especially hard to fit, use the hook.
4.6.3.1 With beading disc
Proceed as follows:
• Secure the rim to the chucking table according to the procedure described in "Securing rims".
• Adequately lubricate the tyre beads and the rim outer edge with a suitable lubricant using the provided brush.
USE ONLY TYRE LUBRICANTS. SUITABLE LUBRICANTS CONTAIN NO WATER, HYDROCARBONS,
OR SILICON.
• Mount grippers 1 (Fig. 36) on the external edge of the rim in the highest point as shown in Fig. 36.
THE GRIPPERS MUST BE TIGHTLY SECURED TO THE EDGE OF THE RIM.
• Move to work position B (Fig. 2, Fig. 4, Fig. 6).
• Lower the chucking table arm completely. Roll the tyre on the platform and hook it to clamp 1 (Fig. 37).
• Lift the chucking table arm with the tyre hooked (see Fig. 37) and turn it anticlockwise by about 15-20 cm. The
tyre will position itself sideways with respect to the rim.
• Move to work position C (Fig. 2, Fig. 4, Fig. 6).
• Position beading disc 2 (Fig. 38) so it is at approximately 1.5 cm (½") from the edge of the rim. Fitting clamp 3 is
at 11 o'clock. Turn the chucking table until the grippers reach the lowest point (6 o'clock).
• Move the beading disc away from the wheel.
• Remove the grippers and fit them in the same position (6 o'clock) outside the second bead.
• Turn the chucking table 90° clockwise until the grippers are at 9 o'clock.
• Move the beading disc forward until it is inside the edge of the rim by about 1-2- cm, making sure that it is 5 mm
from the profile. Begin clockwise rotation making sure that, after a 90° turn, the second bead begins to slide in
the rim groove.
• Once insertion is completed, move the tool away from the wheel, turn it over into "rest" position and remove the
grippers.
• Lower the chucking table until the wheel is resting on the platform.
• Move to work position B (Fig. 2, Fig. 4, Fig. 6).
• Close the chucking table jaws completely, making sure the wheel is held up to avoid dropping.
MAKE SURE THAT THE WHEEL'S HOLD IS SECURE TO AVOID IT FALLING DURING REMOVAL.
FOR HEAVY AND/OR VERY LARGE WHEELS USE AN ADEQUATE LIFTING DEVICE.
• Translate the platform to release the wheel from the chucking table.
With especially soft tyres, simultaneously insert both beads on the jaw so that bead insertion is done only once.
This single operation is ideal for saving time.
4.6.3.2 With a hook
Proceed as follows:
• Secure the rim to the chucking table according to the procedure described in "Securing rims".
• Adequately lubricate the tyre beads and the rim outer edge with a suitable lubricant using the provided brush.
USE ONLY
HYDROCARBONS, OR SILICON.
• Mount grippers 1 (Fig. 36) on the external edge of the rim in the highest point.
THE GRIPPERS MUST BE TIGHTLY SECURED TO THE EDGE OF THE RIM.
• Move to work position B (Fig. 2, Fig. 4, Fig. 6).
• Lower the chucking table arm completely. Roll the tyre on the platform and hook it to clamp 1 (Fig. 37).
• Lift the chucking table arm with the tyre hooked (see Fig. 37) and turn it anticlockwise by about 15-20 cm. The
tyre will position itself sideways with respect to the rim.
• Place the tool carrier arm in "rest" position. Translate it to the inner side of the tyre and hook it into work
position.
• Release lever 1 (Fig. 39) and rotate tool 2 by 180° to position hook 3 on the side of the tyre.
• Move to work position D (Fig. 2, Fig. 4, Fig. 6)
