Mount / demount Head
Checking
Mount a 13 inch diameter aluminium alloy rim
(preferably new) onto the turntable.
Lower the mount / demount head onto the rim
and lock.
By means of the appropriate gauge kit, check
measurements as indicated in fig.33 (for
mount/demount head with roller) and fig.34
(mount / demount head with insert).
Calibration
Loosen all screws securing the mount / demount
head.
Lower the mount / demount head onto the rim
and lock.
Finger-tighten screws A3-A4(fig.37 and ftg.38) in
order to turn the mount / demount head and
obtain the correct position.
Tighten screws A1-A2 (fig.35, 39 mount/demount
head with roller; fig.36, 40 mount / demount head
with insert) to tilt the mount / demount head and
obtain the correct position and then finger-tighten
screw B.
Unlock and raise the hexagonal column, then
lower it onto the rim and lock again.
First tighten screws A1-A2-A3-A4 in torque of
50Nm and check by means of gauges that the
measurements remain the same.
Lastly, tighten screw B to a torque of 50Nm and
carry out checks once again with the gauges.
Periodic checks
After use of the machine for half a year, do regular
check to ensure correct measurements as stated in
Checking. If they are incorrect proceed as follows:
Check that the screws (A1-A2-A3-A4-B) are
tightened properly.
Calibration.
If measurement 2 (roller, fig.35) or measurement
1 (insert, fig.36) are changed, the cause may be
that nut i(fig.42) has loosened.
Tighten or loosen nut i to increase or reduce
lifting range.
If measurement 2 (fig.370) has changed, this
may be due to loose nut e(fig.42) or deformation
of locking plate c (fig.42).in both case simply
adjust the nut, tighten or slacken to increase or
reduce movement range. Secure nuts with
minimum tightening torque 70Nm.
