wheels used with this grinder should be rated for 3,400 RPM or
higher and have a width of 3/4 inch for the 6 inch grinder, and 1
inch for the 8 inch grinder. Grinding wheels for the DELTA
196 must be 6 inch in diameter with a 1/2 inch arbor hole.
Grinding wheels for the DELTA
with a 5/8 inch arbor hole.
Using a wheel that is less than 3/4 inch wide for
the 6 inch grinder, or 1 inch wide for the 8 inch grinder, will cause
vibration and could damage the machine.
ALWAYS maintain a distance of 1/8 inch or -
less between the grinding wheel and both the tool rest and the
spark shields. Adjust the tool rests and spark shields as the
grinding wheels decrease in size with use.
DRESSING THE WHEELS

®
come with a diamond-based wheel dressing tool included. There
is on-board storage for the wheel dressing tool at the rear of the
machine for easy access. Use this tool or any other suitable stick-
type wheel dressing tool to keep your grinding wheels clean and
square.

1.
Bring the wheel dressign tool
rest until it just touches the high point on the face of the

Dress the wheel by moving the wheel dressing tool back

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 to it.
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.
