and tire are on the car. A switch on the console sets the
machine for either static or dynamic balancing. When
the wheel balancing assembly is mounted for static balancing,
it rotates until the heavy spot falls to the bottom.
Weights are added to balance the assembly.
In the dynamic balance mode, the wheel assembly is
rotated at high speed. Observing the balance scale, the
operator reads out the amount of weight that has to
be added and the location where the weights should be
placed.
