LAUNCH
Mount/Demount Head (Old Style)
Checking calibration measurement
Mount a 15 or 16 inch diameter aluminum 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.12(for mount /
demount head with roller)and fig.13(mount /
demount head with insert).
Tighten screws A1-A2 (figs.14,18 mount / demount head with roller;figs.15,19 mount / demount head with insert)
to tilt the mount / demount head and obtain the correct measurements 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 to tightening 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 half a year of duty check measurements as stated in Checking. If they are incorrect proceed as follows:
Check that the screws(A1-A2-A3-A4-B) are tightened properly and repeat calibration as per Calibration.
If measurement 2 for the mount / demount head with roller (fig.12) or measurement 1 for mount / demount head
with insert (fig.13) are changed, the cause may be that adjusting nut (fig.10) has loosened.
Tighten or loosen the nut to increase or reduce lifting range.
If the measurements do not correspond proceed as
follows:
Calibration
Loosen all screws securing the mount / demount
head .
Lower the mount / demount head onto the rim and
lock it.
Finger-tighten screws A3-A4(figs.16 and 17) in
order to turn the mount / demount head and obtain
the correct measurements.
