the wheels' swing to left or right when performing
run-out compensation operation, causing the
inaccurate run-out compensation.
2. You are required to swing the vehicle tires when

vehicles are linked (i.e. when left wheel rotates,
the right wheel rotates, too), and you want to
perform run-out compensation operation, you
must hold the right (left) wheel when you rotate
the left (right) wheel, and you should notice that
force from you hands must be balanced (in order
to avoid wheel's swing to left and right and
causing inaccurate run-out compensation).
Meanwhile you should check if the probe rods
are level or not. If not, it is necessary to adjust
the probe rods level by the way of rotating the
wheels. You should note that the probe rods
mustn't be adjusted level by the way of loosing
them.
