Fitting - Butler NAV11 Manuel D'instructions

• While doing this, jerk the beading disc forward until the second bead is removed. Continue doing this until the
tyre protrudes half-way (see Fig. 50).
• Tilt up the tool carrier arm and place it in "rest" position after having unhooked it.
• Place mobile platform 1 (Fig. 29) directly under the wheel and lower the chucking table until the wheel rests on
the platform.
• Move to work position B (Fig. 2, Fig. 4, Fig. 6).
• Translate the platform outwards until the tyre is completely dislodged from the rim (in case of tyres with inner
tube, make sure that the valve hasn't been damaged during removal).
THE REMOVAL OF THE BEADS FROM THE RIM CAUSE THE TYRE TO FALL. ALWAYS MAKE SURE
THAT NO ONE IS STANDING IN THE WORK AREA.
• Remove the rim from the chucking table
• Place the tyre on the platform with the ring facing the chucking table.
• Secure the ring to the chucking table by following the procedure described in "Securing the wheel".
THE TYRE IS NOT FIXED TO THE RING AS SECURELY AS IT IS TO THE RIM, THEREFORE DURING
FITTING IT COULD COME OFF CAUSING HARM TO PEOPLE AND THINGS.
• Move to work position D (Fig. 2, Fig. 4, Fig. 6).
• Lift the wheel
• Place the tool carrier arm in work position (on the inner side of the wheel).
• Position the chucking table in such a way that the beading disc is aligned with the inner bead of the tyre.
• Turn the chucking table while moving the beading disc forward until the tyre has been completely dislodged
from the ring.
THE REMOVAL OF THE BEADS FROM THE RING CAUSES THE TYRE TO FALL. ALWAYS MAKE
SURE THAT NO ONE IS STANDING IN THE WORK AREA.

4.8.2 Fitting

• Place the tool carrier arm in "rest" position and make sure that it is secured with the safety stop. If it has been
removed, fix the rim to the chucking table as described in "Securing rims". If the wheel features an inner tube,
position the rim with the valve slot facing downwards (at 6 o'clock).
• Lubricate the entire outer edge of the rim and the tyre beads.
• Move to work position B (Fig. 2, Fig. 4, Fig. 6).
• Position mobile platform 1 (Fig.29) so as to allow the upward motion of the tyre (if the wheel features an inner
tube, position the rim with the valve slot facing downwards at 6 o'clock).
• Position the chucking table so the rim is centred with the tyre.
• Translate platform 1 (Fig. 29) inwards to insert the rim in the tyre (for tyres featuring an inner tube, push in the
valve so as not to damage it). Move forward until the rim is completely inserted in the tyre.
• Insert the outer edge ring on the rim with the stop ring fitted (if the rim and ring feature fixing slits, they must be
in phase with each other.
• Move to work position C (Fig. 2, Fig. 4, Fig. 6).
• Place the tool carrier arm on the external side then lower it into work position with the beading disc facing the
wheel. If the outer edge ring is not sufficiently fitted on the rim, position the chucking table until the ring is near
the beading disc. Move the beading disc forward and then turn the chucking table until the housing of the O-
Ring (if featured) is uncovered.
• Lubricated the O-Ring and place it in its housing.
• Move to work position B (Fig. 2, Fig. 4, Fig. 6).
• Position ring 1 (Fig. 51) on the rim, fit the stop ring with the help of the beading disc as shown in Fig. 51.
• Tilt up the tool carrier arm and bring it to "rest" position after having unhooked it.
• Place mobile platform 1 (Fig. 29) directly under the wheel and lower the chucking table until the wheel rests on
the platform.
• Close the chucking table jaws completely and translate the platform outwards until the rim has been completely
removed, making sure the wheel is held up to avoid dropping.
CLOSING THE CHUCKING TABLE CAUSES THE WHEEL TO FALL.
ALWAYS MAKE SURE THAT NO ONE IS STANDING IN THE WORK AREA.
