4. Remove outer grinding wheel flange and
paper disc.
5. Remove grinding wheel from spindle. Take
note of paper or fiber disc between wheel
flanges and wheel. These cushion the pres-
sure of the wheel flanges and help distribute
pressure more evenly. They also help reduce
damage to the flanges.
6. Verify flatness of inner and outer flanges
by placing them on a level surface. If either
flange is warped or damaged, replace it.
8. Re-assemble outer wheel guard using hard-
ware removed in
Step 2.
9. While standing away from line of rotation,
turn grinder
ON and run new grinding wheel
for at least 1–2 minutes before standing in
front of it. This helps protect you if the wheel
has internal damage that will cause it to fly
apart from the centrifugal force of rotation.
— If grinder runs smoothly, grinding wheel
may now be used.
— If wheel appears to wobble, grinder
vibrates excessively, or any other unsafe
condition appears with new wheel, stop
grinder and refer to
Troubleshooting on

Paper Discs
NEVER assemble grinding wheel on spindle
without paper or fiber discs between wheel
and flange. Not using discs can put stress
on wheel, causing it to crack and possibly
fly apart.
Warped wheel flanges can contribute to
grinding wheel breaking and flying apart.
Never use warped wheel flanges. Always
check flanges before re-installing grinding
wheel.
7. Mount new grinding wheel in order shown
in
Figure 19. Tighten M16-2 hex nut snugly
but do not over-tighten. Over-tightening can
stress and crack wheel.

Tip: Hold grinding wheel with free hand to

hand threads. Turn it clockwise to loosen.
