  • Page 44: Machine Calibration For The Moto Wheel Type

    4.3 Machine calibration for the MOTO wheel type The calibration for MOTO wheel type (motorcycle wheels) is completely separated from CAR/SUV wheel type because in the calibration for MOTO a specific adaptor for motorcycle wheels is used and this slightly the shaft balancing. If the calibration for MOTO wheel type has not been done and the user try to spin the wheel for balancing in the MOTO wheel type mode, the machine will not run and will display an error code ERR 031.
  • Page 45 Mount the motorcycle adaptor on the shaft as shown here. The flange for motorbike wheels must be installed so that the “CAL” markings on the shaft flange flange motorbikes line up. Lower the wheel guard: the machine will run a launch. At the end of the launch, the machine will display the message shown here.
  • Page 46 If the weight position is significantly different from the vertical position, the machine will refuse to perform the spin and it will display an error code ERR 043. If the motorcycle adaptor is near to the vertical position but not in the precise vertical position, the machine will spin but at the end of the calibration each balancing spin will have an error in the balancing angular position of the weights.
