Ring Testing and Installing Grinding Wheels
1. Suspend the wheel on the arbor but do not tighten the spindle nut.
2. Imagine a vertical line up the center of the wheel. With a hard plastic or wood object, tap the
wheel at 45 degrees on each side of the vertical line, 1” – 2” from the wheel’s edge.
3. Rotate the wheel 180 degrees and repeat the tapping test.
4. If the wheel rings with a clear tone, the wheel is safe and may be installed. If the wheel has a
dead thud at any of the points, it is damaged and cannot be used.
5. If the wheel is safe, tighten the spindle nut on the arbor. Tighten snugly, but do not overtighten as
this may crack the wheel. The spindle nut will tighten further under normal operation.
Before Each Use
⚠
WARNING

Always check for damaged or worn out parts before using the benchtop grinder.

The benchtop grinder needs to be bolted to the work surface before you start operation.
Test the Grinding Wheel
1. Imagine a vertical line up the center of the wheel. With a hard plastic or wood object, tap the
wheel at 45 degrees on each side of the vertical line, 1” – 2” from the wheel’s edge.
2. Rotate the wheel 180 degrees and repeat the tapping test.
3. If the wheel rings with a clear tone, the wheel is safe and may be installed. If the wheel has a
dead thud at any of the points, it is damaged and cannot be used. Replace the wheel.
Tool Rest Adjustment
Adjust the tool rest to the desired grinding angle. Keep the tool rest approximately 1/16” away from
the surface of the grinding wheel in order to provide appropriate workpiece support.
