Wheel Blotters and Mounting Flanges
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 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.
Emergency Applications
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.
WARNING
z
Do not grind with a cut-off wheel or put
pressure on the sides.
z
Do not mount wheel if blotters are
damaged. Do not destroy cushioning
effect by making mounting bolts too tight.
Never fasten while applying your weight.
Otherwise the thread could be broken.
Proper torque is 20 N•m (200 kgf•cm).
z
Examine wheel carefully before use. Do
not use if wheel is warped, damp, cracked,
chipped or cutting area shows heat
discoloration.
z
A wheel once dropped cannot be trusted.
Discard a wheel if you drop it.
Ring Testing Wheels
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”.
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.
