MAINTENANCE

Grinding Wheels

The use of accessories and attachments not recommended by

Delta® may result in a risk of injury.

Grinding wheels used with this grinder should be rated for 3600 RPM or higher and have a width of 1" . Grinding wheels for the DELTA® 23-198 must be 6" in diameter with a ½" arbor hole. Grinding wheels for the DELTA® 23-199 must be 8" in diameter with a 5/8" arbor hole.

Using a wheel that is less than ¾" wide for the 6 in. grinder, or 1" wide for the 8 in. grinder, will cause vibration and could

damage the machine.

ALWAYS maintain a distance of 1/8" or less between the grinding wheel and the tool rest. Adjust the tool rests and spark guards as the

grinding wheels decrease in size with use.

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.

Dressing the Wheels

Your DELTA® 23-198 (6 in.) Grinder or 23-199 (8in.) Grinder come with a diamond-based wheel dresser included. There is on-board storage for the dresser at the rear of the machine for easy access. Use this tool or any other suitable stick-type dresser to keep your grinding wheels clean and square.

To dress the wheel, refer to Figure 8 and do the 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.
