WARNING
Only original equipment should be used during operation.
WARNING
Get to know your machine. The best way to prevent accidents and obtain top
performance from the machine is to ensure that all operators know how the
machine works.
Learn the function and location of all the commands.
Carefully check that all commands on the machine are working efficiently.
To avoid accidents and injury, the machine must be installed properly, operated
correctly and serviced regularly.
USING THE WHEEL CENTRING
Standard truck wheel centring flanges
The following parts are provided:
- Step flange with diameters 220 and 280 mm for rear pre-centring of bus and HGV
wheels.
- Step flange with diameters 160, 176 and 200 mm for rear pre-centring of truck, van
and trailer wheels.
- Stop flange with holes for fitting the tapered pins.
- Standard set of five tapered screws for centring rims with fixing holes from Ø 18 to Ø
35 mm.
- Set of five maxi tapered screws for centring rims with fixing holes from Ø 28 to Ø 47
mm on the flange.
The procedure for centring a wheel using the parts described above must be carried
out as follows:
Fit the step flange suitable for the type of rim to be balanced on the balancing
machine and fix it to the balancing machine flange using the two screws provided;
- fit the pins of the RFT caliper into two adjacent fixing holes on the rim (fig. 12);
- find the scale on the RFT caliper gauge corresponding to the number of fixing holes
in the rim (e.g. 10) and on it read the diameter of the circumference on which these
holes are arranged and the number which identifies the corresponding holes on the
stop flange (e.g. 225; 6);
- fit the tapered screws (standard or maxi) suitable for the diameter of the holes in the
rim on the stop flange, in the holes identified by the number found previously. The
screws must be fixed so that the nuts are on the numbered side of the stop flange;
- fit the wheel on the balancing machine shaft as described in the "USING THE LIFT
CARRIAGE" section, taking care that the central hole of the rim is mated correctly with
the step flange.
Note
The rear contact between the rim and the flange is intended to pre-centre the wheel; it
is therefore absolutely normal for there to be some play between the diameter of the
