H7758/H7759 8" & 10" Bench Grinders
Figure 4. Assembly order for wheel installation.
NEVER assemble a grinding wheel on the
arbor without paper or fiber discs between
the wheel and the flange. Not using the
discs can put undue stress on the wheel,
causing it to crack and possibly fall apart.
ALWAYS visually inspect and perform a
“ring test” on a wheel before assembly. DO
NOT use damaged wheels!
6. Re-install the spark deflectors and eye-
shields.
7. 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
4. Always make certain there is a paper or
fiber disc between the wheel flanges and
the wheel itself. Tighten the nut snugly but
DO NOT over-tighten. Over-tightening can
crack the wheel.
