7.Spin the wheel so it rotates one full turn and comes to rest with the heaviest side hanging down at six O'clock. This may take a few times to find the exact location.
8.Using a pencil, draw a line on the wheel at the six O'clock position to mark the heaviest side.
9.Line up the closest dog with the line you just drew and lock it in place. This dog will now be positioned at the heaviest side of the wheel and will be called dog "A".
10.Using the scale as a guide, position the other two "B" dogs so they are both evenly spaced 120° degrees apart from the "A" dog. At this point, all dogs will be 120° apart from one another. "B" dogs will be the two dogs that will be moved to balance out the location that is out of balance.
11.Rotate the wheel to 90° degrees and release it to observe the direction that the wheel rotates out of balance. Move each "B" dog toward one another and away from dog "A" in 1° degree increments to balance out the wheel.
For example: depending on the amount of balance correction, the distance between the two "B" dogs will decrease, and the distance between the "B" dogs and "A" dog will increase. This step must be repeated as many times as required until the wheel will not rock back and forth by itself the heavy spot.
12.When you are satisfied with the wheel balance settings, install the grinding wheel on the machine, and test run for five minutes to verify the balance. If any problems are detected, repeat the balancing procedure.
