Page 30: Machine Calibration For The Moto Wheel Type
6.3 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 31 At the end of the spin, the machine will display the writing h12 CAL. Apply the calibration weight on the internal side as shown in the picture. The calibration weight must be applied on the hole in the upper side. Move the motorcycle adaptor to a stable vertical position with the calibration weight in the upper side as shown in the picture.
