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.
3. Remove arbor nut (see Figure 18
).
Tip: Hold grinding wheel with free hand to stop it
from turning while loosening the arbor nut.
. Note: Nut on left side of grinder has left-hand
threads. Turn it clockwise to loosen.
4. Remove grinding wheel outer flange and paper disc.
5. Remove grinding wheel from spindle. Take note of
paper or fiber disc between wheel flanges and wheel
(see
Figure 19
). These cushion the pressure 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 flat surface. If either flange is warped or
damaged, replace it.
7. Mount new grinding wheel, as shown in Figure 19
.
Tighten arbor nut snugly but do not over-tighten to
avoid stressing and cracking wheel.
8. Re-assemble outer wheel guard using hardware
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 Page 24.
