wheel is smaller than 4" or is an unusual shape) as
follows:
a. Suspend wheel using a dowel or nger through the
arbor hole.
b. Tap the at side of the wheel with a light non-metallic
object, such as a screwdriver handle, at a point 45º
from the vertical center line on each side of the wheel
and 1-2 inches from the edge of the wheel (see
illustration).
c. Rotate the wheel 90º and repeat the test until the
entire wheel has been checked.
