    Use and maintenance manual 8. Diagnostics INCONSISTENT UNBALANCE READINGS In some cases, when a wheel that has just been balanced is repositioned on the balancer, the machine can detect an unbalance. This is not a machine problem but is due to faulty mounting of the wheel on the flange. In other words, when mounting the wheel after initial balancing, it has taken another position with respect to the balancer shaft axis.
