MOUNTING NON-HUBBED WHEELS (FIG. 9, 10)
Depressed center Type 27 grinding wheels must be used with
included flanges.
NOTE: The stamped steel quick-change backing flange (G2) is
for use with D28140, D28144 and D28144N for Type 27 grinding
wheels only. Refer to page 10–12 for more information.
1. Install the stamped steel quick-change backing flange (G2)
(D28140, D28144, D28144N only) for Type 27 6" (152 mm)
wheels or the quick-change backing flange (G1) for
all other non-hubbed wheels on spindle (Q) with the raised
section (pilot) against the wheel. Be sure the backing flange recess
is seated onto the flats of the spindle by pushing and twisting the
flange before placing wheel.

2. Place wheel against the backing flange, centering the wheel on
the raised section (pilot) of the backing flange.
3. While depressing the spindle lock button, thread the clamp
nut (H) on spindle. If the wheel you are installing is more
than 1/8" (3.17 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"
(3.17 mm) thick or less, place the threaded clamp nut on the
spindle so that the raised section (pilot) is not against the wheel.
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
H
height of the pilot prevents the clamp nut from holding 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.
1. Allow the tool to reach full speed before touching the tool to the
work surface.
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
tool and work surface.
4. Continuously move the tool in a forward
and back motion to avoid creating
gouges in the work surface.
