The DELTA

23-198 comes with one 6" aluminum oxide

grinding wheel (gray) and one 6" composite grinding

wheel (white). The DELTA

23-199 comes with one

8" aluminum oxide grinding wheel (gray) and one 8"

composite grinding wheel (white). For best results, and

to properly maintain the grinding wheels, follow these

recommendations:

1. Keep the wheels properly dressed.
2. Do not force the work against a cold wheel. Always

run the grinding wheel for one full minute before

applying a workpiece.

3. Use only balanced wheels with your grinder. Using

balanced wheels adds years to the life of the

bearings on the grinder. By eliminating the most

common source of vibration, your grinding projects

will be more accurate.

following:

1. Bring the dresser (A) forward on the tool rest until it

just touches the high point on the face of the wheel.

2. Dress the wheel by moving the dresser back forth.
3. Repeat this operation until the face of the grinding

wheel is clean and the edges are square.
