Installing/Removing Grinding Wheel - Grizzly T32720 Owner's Manual

Installing/Removing
Grinding Wheel
Wheels with varying grit are useful for different
operations and workpiece materials. DO NOT
leave a wheel mounted when the machine is not
in use.
ALWAYS visually inspect and perform a
"ring test" on a wheel before installing. DO
NOT use damaged wheels!
Tool Needed
Open-End Wrench or Socket
To install/remove grinding wheel:
1. DISCONNECT MACHINE FROM POWER!
2. Remove arbor hex nut and outer flat washer
(see Figure 20).

stop it from turning while loosening arbor nut.
Note: Spindle on left side of sharpener has
left-hand threads. Turn it clockwise to loosen.
3.
Remove grinding wheel from spindle.

Verify flatness of inner and outer washers
by placing them on a level surface. Replace
warped or damaged washers and blotters.

Warped washers can contribute to grinding
wheel breaking and flying apart. Never use
warped washers. Always check washers
before installing grinding wheel.
5. Mount new grinding wheel in order shown
in Figure 21. Tighten arbor hex nut snugly
but do not over-tighten. Over-tightening can
stress and crack wheel.
— Paper discs or "blotters" should always be
used to absorb any pressure from mount-
ing hardware to prevent wheel from crack-
ing. Grinding wheel that ships with this
sharpener (PT32720003) already comes
with a blotter present on each side. Part
number PT32720105 on Page 36 can
be used to replace missing or damaged
blotter. If replacing with a different grind-
ing wheel, refer to wheel manufacturer to
obtain correct blotters.

6. While standing away from line of rotation, turn
sharpener ON and run new grinding wheel for
at least 1–2 minutes before standing in front
of it. This helps protect you if wheel has inter-
nal damage that will cause it to fly apart from
centrifugal force of rotation.
— If sharpener runs smoothly, grinding wheel
may now be used.
