MOUNTING NON-HUBBED WHEELS
(FIG. 10)
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" (3.17 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.
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
FIG. 10
orientation of the threaded clamp nut. If a thin wheel is installed with
D
the pilot on the clamp nut toward the wheel, it will spin because the
height of the pilot prevents the clamp nut from holding the wheel.

SURFACE GRINDING WITH GRINDING WHEELS (FIG. 11)
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
E
tool and work surface.
4. Continuously move the tool in a forward
1/4" WHEELS
(6.35 mm)
and back motion to avoid creating
gouges in the work surface.
5. Remove the tool from work surface before turning tool off. Allow
Clamp Nut
the tool to stop rotating before laying it down.
EDGE GRINDING WITH GRINDING WHEELS (FIG. 12)
WARNING: Wheels used for cutting and edge grinding may break
Backing Flange
if they bend or twist while the tool is being used to do cut-off work or
1/8" WHEELS
deep grinding. To reduce the risk of serious injury, limit the use of
(3.17 mm)
these wheels with a standard Type 27 guard to shallow cutting and
notching (less than 1/2" in depth). The open side of the guard must
be positioned away from the operator. For deeper cutting with a
Clamp Nut
Type 1 cut-off wheel, use a closed, Type 1 guard. Refer to the
Accessories Chart for more information. Type 1 guards are
available at extra cost from your local dealer or authorized service
center.
