ENGLISH • Instructions manual
Note: When working on UHP or self supporting run-flat tyres to facilitate external locking using PT150 is always advised.
RIM CLAMPED FROM THE INSIDE (wheels from 12-23")
Press the pedal (5, Fig. E) all the way down to close the 4 sliding clamps (6, Fig. E) completely.
Put the wheel on the table top and depress pedal (5, Fig. E) all the way down.
The 4 sliding clamps will open and clamp the wheel.

10.3 DEMOUNTING

ATTENTION: For mounting and demounting operations with the tyre changers
equipped with PT 150 see the "istruction manual" for proper use.
1) Depress the pedal (7, Fig. E) to bring the column (8, Fig. E) to its working
position.
Do not place your hands on the wheel: when moving the
arm to its working position your hands could be crushed
between the rim and the mounting head.
2) Position the mount/demount tool (16, Fig. E) by hand against the edge of
the rim.
Press the yellow button on the handle (9, Fig. E).
The hexagonal arm (10, Fig. E) and horizontal arm (11, Fig. E) will be automati-
cally locked in position and, at the same time, the mount/demount head (16,
Fig. E) will be lifted 2 mm off the rim edge.
3) With the help of the bead lifting tool (1, Fig. H) inserted over the forward
end of the mount/demount tool (16, Fig. E) 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.
4) Hold the bead lifting tool in this position and hold the pedal (1, Fig. E)
depressed to turn the table top (2, Fig. E) clockwise until the tyre comes
completely off the rim.
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 (1) as shown in Fig. H.
5) Remove the inner tube if the tyre has one.
6) Repeat the procedure described in point 3 to demount the lower bead.
