Hubbed wheels install directly on the
1.Remove backing flange (D) by pulling away from the tool.
2.Thread the wheel on the spindle by hand.
3.Depress the spindle lock button and use a wrench to tighten the hub of the wheel.

(E) on spindle. If the wheel you are installing is more than 1/8" |
(3.31 mm) thick, place the threaded clamp nut on the spindle so |
that the raised section (pilot) fits into the center of the wheel. If |
the wheel you are installing is 1/8" (3.31 mm) thick or less, place |
the threaded clamp nut on the spindle so that the raised section |
(pilot) is not against the wheel. |
4. While depressing the spindle lock button, tighten the clamp nut |
with a wrench. |
5. To remove the wheel, depress the spindle lock button and loosen |
the threaded clamp nut with a wrench. |
NOTE: If the wheel spins after the clamp nut is tightened, check the orientation of the threaded clamp nut. If a thin wheel is installed with the pilot on the clamp nut against the wheel, it will spin because the height of the pilot prevents the clamp nut from holding the wheel.

2. Apply minimum pressure to the work surface, allowing the tool |
to operate at high speed. Grinding rate is greatest when the tool |
operates at high speed. |
3. | Maintain a 20˚ to 30˚ angle between the | FIG. 10 |
| tool and work surface. |
|
4. | Continuously move the tool in a forward |
