Standard Wheel Demounting - Nussbaum TC 110 PRO Manual De Instrucciones

(1*/,6+ ‡ ,QVWUXFWLRQV PDQXDO
Standard wheel means a wheel of a car or light commercial
vehicle, with a steel or aluminium alloy rim and a traditional
type tyre (non-Run-Flat, UHP or low profile).
1) Put the mounting head (13, Fig. H) against the edge
of the rim by manually moving the horizontal arm (9, Fig.
H) and the exagonal bar (8, Fig. H).
2) Lock the mounting head (13, Fig. H) by using the
lever (7, Fig. H).
The head will be automatically lifted by 2 mm. up the
edge of the rim.
3) Using the handle-wheel (15, Fig. H) push the mount-
ing head (13, Fig. H) 2 mm. far from the edge of the rim.
NB. Place the valve nearly under the
tyre demounting column to avoid
any pressure sensor braking.
4) With the help of the bead lifting tool (14, Fig. H)
inserted over the forward end of the mount/demount tool
(13, Fig. H) and below the top bead, lift the upper bead
over the knob portion of the mount/demount head.
N.B. To prevent pinching the inner tube, do this operation
with the valve about 10 cm to the right of the mount/
demount tool.
5) Hold the bead lifting tool in this position and hold the pedal (1, Fig. H) depressed to turn the table top (2, Fig. H) clockwise
until the tyre comes completely off the rim.
WARNING!
To prevent industrial accidents, keep hands and other parts of the body as far from the tool arm as
possible when the table top is turning.
Note: If the bead rubber is particularly hard and stiff, it will tend to slip off the mount/demount tool. To prevent this,
before turning the table top clockwise, rotate it anticlockwise for a couple of centimeters while holding the bead lifting
tool (14, Fig. H) as shown in Fig. N.
6) Remove the inner tube if the tyre has one.
7) If the tyre has a pressure sensor, turn the turntable to bring the
valve under the demounting head.
8) Repeat the procedure described in points 4 and 5 to demount
the lower bead.
