1. Install the unthreaded
flange (G) on spindle (E) 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 locking flange
(H) on spindle. If the wheel you are
installing is more than 1/8" (3.17 mm)
thick, place the threaded locking flange 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 locking flange on the spindle so that the raised section
(pilot) is not against the wheel.
4. While depressing the spindle lock button, tighten the locking
flange with a wrench.
5. To remove the wheel, depress the spindle lock button and loosen
the threaded locking flange with a wrench.
NOTE: If the wheel spins after the threaded locking flange is
tightened, check the orientation of the threaded locking flange. If a
thin wheel is installed with the pilot on the locking flange against the
wheel, it will spin because the height of the pilot prevents the locking
flange from holding the wheel.

SURFACE GRINDING WITH GRINDING WHEELS (FIG. 10)
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.
5. Remove the tool from work surface before turning tool off. Allow
the tool to stop rotating before laying it down.
EDGE GRINDING WITH GRINDING WHEELS (FIG. 11)
CAUTION: Wheels used for edge grinding and cutting may break
or kick back if they bend or twist while the tool is being used. In all
edge grinding/cutting operations, the open side of the guard must be
positioned away from the operator. Edge grinding/cutting with a
Type 27 wheel must be limited to shallow cutting and notching—less
than 1/2" (13 mm) in depth when the wheel is new. Reduce the depth
of cutting/notching equal to the reduction of the wheel radius as it
