Mounting the Grinder to the Workbench
Before attempting to use this grinder, it must be properly mounted to a workbench or grinding stand.
Note: Bench grinders vibrate. Grinder movement during high-speed rotation may cause injury to the
operator or damage to the workpiece. Mount the grinder securely to a sturdy workbench or grinding
stand.
1. Position the grinder on the workbench. Mark the workbench through the two mounting holes
located in the grinder base (see illustration below).
2. Drill holes in the workbench at the marks. Using two long bolts, washers, lock-washers, and
nuts, as shown (not supplied), secure the grinder to the workbench (illustration).
Testing and Installing the Grinding Wheel
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.
