Installing or Changing a Wheel
1. Make sure the bench grinder is turned
off and unplugged.
2. Loosen the tool rest knob, and slide the
tool rest away from the wheel.
3. Loosen the spark deflector screw, and
remove the deflector.
4. Use a screwdriver to remove the three
wheel guard cover screws.
5. Remove the wheel guard cover.
6. Fit an appropriately sized wrench on
the wheel nut.
7. Loosen the wheel nut in a clockwise
direction for the left side and a counter-
clockwise direction for the right side.
8. Remove the nut, the outer flange and the grinding wheel from the spindle shaft.
9. Inspect the new wheel carefully to ensure
there are no cracks, chips or other damage.
10. Subject the grinding wheel to a “Ring Test”:
a. Make sure the grinding wheel is clean and free of dust and debris.
b. Suspend the wheel by its arbor hole and tap each of its four quadrants lightly
with a nonmetallic item.
c. If the wheel emits a ringing sound, it is in good condition. If the wheel emits a
dull sound, do not use the wheel. IT MAY BE CRACKED.
11. Place the ring-tested wheel and the outer flange on the spindle shaft.
12. Make sure the grinding wheel and outer flange are properly seated on the spindle
shaft.
13. Place the wheel nut on the spindle shaft.
14. Tighten the wheel nut in a counter-clockwise direction for the left side and a
clockwise direction for the right side.
15. Replace the wheel cover and attach the three guard cover screws.
WIRE WHEEL
A wire wheel can be used with your grinder.
You will need to add a spacer (as shown)
to allow the arbour hex nut to tighten correctly.
