• Turn the adjustment device using the knob until securing it into the new position (A
Fig. 18d).
• Check that the locking pin is firmly secured in its housing.
The setting of the diameter range (10"→20" or 14"→24" for TCN 8240 - 10"→22"
or 14"→26" for TCN 8260), using the adjustment device, must be carried out with
the turntable completely stopped without acting on the controls.
- Turntable jaws are opened and closed by sequentially pressing the control pedal
.
- With the jaws completely closed, lightly press the
control pedal
position (Fig. 19a).
In this configuration, it is possible to carry out dead-
man control of jaws opening and then stop them in
the desired position.
- If the rim is blocked from the outside (Fig. 19b),
pre-position the locking wedges using the references
of the diameters shown on the turntable and the red
notch on the jaw (Fig. 19c).
E.g.: Rim 18", pre-position the jaws making the red
notch match with value 18".
- If the rim is blocked from the inside (Fig. 19d), it is
not necessary to pre-position the locking wedges. The
very shape of the wedge brings the rim to be locked
into the correct position.
- Place the wheel (with the narrow shoulder of the
rim facing up) on the turntable,
- Push it slightly downwards and operate the control
pedal
to lock the wheel in position (fig.20).
