H8126 Wide Wheel Ginder
4. Remove the outer wheel flange and the
paper disc. Pull the wheel free from the arbor,
but leave the paper disc and a wheel flange
on the other side of the wheel.
Figure 12. Typical assembly order for wheel
installation.
NEVER assemble a grinding wheel on the
arbor without paper or fiber discs between
the wheel and the flange. Omitting the discs
can put uneven stress on the wheel, causing
it to crack and possibly fly apart. ALWAYS
“ring test” a wheel before assembly to make
certain it has no cracks or flaws.
6. Run a new wheel for at least one minute
while standing clear of the line of rotation. If a
wheel does have defects it will generally fail
as soon as it gets up to full speed.
5. Mount the new wheel as shown in Figure
12. Always make certain there is a paper or
fiber disc between the wheel flanges and the
wheel itself. Tighten the arbor nut snugly but
DO NOT over-tighten. Over-tightening can
crack the wheel.
