OPERATION
WARNING!
In rim clamping, make sure that jaws are properly positioned on the rim, so as to prevent the tire from
falling over
1) Take the mobile control unit to work position B.
2)
Pull the tool-holder arm (14, fig. D) into the upright position.
3)
Operating from the mobile control centre, move the sliding table (13, fig. D) away from the self-centering chuck and place the tire
assembly in vertical position over the sliding ramp.
DANGER! POTENTIALLY HAZARDOUS OPERATION!
Do it manually only if you are certain you can keep the tire assembly balanced. For large and heavy tyres an
adequate lifting device must be used.
4)
Continuing to operate from the mobile control centre, lift or lower the arm in order centre the self-centering chuck (3, fig. A) relative
to the rim.
5)
With the jaws (22, fig. A) in the closed position, move the tire assembly on the sliding ramp to the self-centering chuck. Operate the
chuck switch (5, fig. C) to open the self-centering chuck and clamp the inner side of the rim.

The most convenient clamping position on the rim may be selected according to figs E/1 - E/2 - E/3 - E/4 - E/5 and E/6.
Always remember that the safest clamping is on the central flange.
For rims with drop center clamping, clamp the wheel so that the drop center is near the outside of the rim (fig. E/1).
For rims exceeding a diameter of 46" and without a flange with center hole, the rim can be clamped with the 4 clamping extensions
provided on demand (# 9299270)
(# 9299272) LIGHT-ALLOY RIM CLAMPING
A set of clamps - especially designed for operating on light alloy rims without damaging them - is available upon request.
These clamps are to be inserted (bayonet-like mounting) into the jaw support of the self-centering chuck (see fig. E/7).
Thanks to a wing screw the clamp can be locked on the support.
Clamp the rim as illustrated in fig. E/8. The specially-made alloy-rim pliers are also available (# 9299271).
