Set-Up & Use
Once your grinder is assembled but before you put it to work, it’s important to check the wheels to ensure they’re balanced. A grinding wheel that is out of balance will have greater vibration and instability, and result in an uneven grind.
Checking Wheel Balance
First, turn on the machine and check the wheels by sight for wobble (Photo 1).
Photo 1 – Focus on the gap between the side of the wheel and the wheel cover to reveal any oscillation.
If either wheel is unbalanced, do not use the grinder before correcting it by following these steps:
1) Remove the wheel cover.
2) Mark a line across the wheel and outer wheel flange (Photo 2).
Photo 2 – The line records the starting position.
3) Loosen the arbour hex nut, rotate the outer wheel flange and retighten the hex nut (Photo 3).
Photo 3 – Position the flange to a different position, and test the wheel for trueness.
4) Spin the wheel by hand to check on the wobbliness.
5) Repeat steps 3 and 4 until the wheel spins true (Photo 4).
Photo 4 – Reposition the flange and retest, if necessary, until the wobble is gone.
