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 finger 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".
Wheel blotters attached to both sides of reinforced
wheels are cushions needed to equalize the
pressure of the mounting flanges from wear if
slippage between the wheel and the flanges
occurs. The blotters are 108 mm (4
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 cut-off saw has applications in fire fighting and
rescue work. An ECHO QUIK-VENT roof venting
saw is also available. Both of these units, however,
can cause sparks and should not be used in an
explosive atmosphere or where they could start a
fire.
IMPORTANT
If a wheel being "ring tested" is dirty or damp or
is tapped at the vertical center line, the resulting
sound will be muffled and not reliable.
