MOUNTING NON-HUBBED WHEELS
(FIG. 8)
Depressed center Type 27 grinding wheels
must be used with included flanges. Refer
to Accessories and Attachments for more
information.
1. Install the backing flange (D) on spindle (B)
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 (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 toward the wheel, it will spin because the
FIG. 8
height of the pilot prevents the clamp nut from holding the wheel.

SURFACE GRINDING WITH GRINDING WHEELS (FIG. 9)
1. Allow the tool to reach full speed before
B
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.
E 4. Continuously move the tool in a forward and back motion to avoid
creating gouges in the work surface.
1/4" WHEELS 5. Remove the tool from work surface before turning tool off. Allow
(6.35 mm)
the tool to stop rotating before laying it down.
EDGE GRINDING WITH GRINDING WHEELS (FIG. 10)
Clamp Nut
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
Backing Flange
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
1/8" WHEELS
of cutting/notching equal to the reduction of the wheel radius as it
(3.31 mm)
wears down. Refer to the Accessories Chart for more information.
Edge grinding/cutting with a Type 1 wheel requires usage of a
Clamp Nut
Type 1 guard.
1. Allow the tool to reach full speed before touching the tool to the
work surface.
