WARNING
Cracks or defects in a wheel may not be visible. To help in verifying that a
wheel is ok to use, a "ring test" must be made immediately before mounting
all new or used wheels.
Put your fi nger through the mounting hole to support the wheel. Use a non-
metallic handle of any small tool or a small piece of wood to lightly tap (do
not hit) the wheel in the locations shown in the illustration. Do not tap wheel
on the edge. Uncracked wheels will make a ringing sound, wheels with
cracks or concealed cracks will make a dull "clunk".
"Tap" Here
Wheel blotters attached to both sides of reinforced
wheels are cushions needed to equalize the
pressure of the mounting fl anges from wear if
slippage between the wheel and the fl anges
occurs. The blotters are 108 mm diameter. Take
care that the blotters do not become gouged or
deeply scratched and that there is no foreign
material on them when mounting the wheel.

The cutter has applications in fi re fi ghting and
rescue work. This unit, however, can cause
sparks and should not be used in an explosive
atmosphere or where it could start a fi re.
IMPORTANT
If a wheel being "ring tested" is dirty or damp or
is tapped at the vertical center line, the resulting
sound will be muffl ed and not reliable.
