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 but-
ton, thread the clamp nut (H) on spin-
dle. If the wheel you are installing is
more than 1/8" 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" 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 but-
ton, tighten the clamp nut with a wrench.
5. To remove the wheel, depress the spin-
dle 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.
SURFACE GRINDING WITH GRINDING WHEELS
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
CAUTION: Wheels used for cutting and edge grinding may break
1/4" WHEELS if they bend or twist while the tool is being used to do cut-off work or
deep grinding. To reduce the risk of serious injury, limit the use of
these wheels with a standard Type 27 guard to shallow cutting and
Clamp Nut
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
Type 1 cut-off wheel, use a closed, Type 1 guard. See the chart on
pages 4-5 for more information. Type 1 guards are available at extra
Backing Flange
cost from your local dealer or authorized service center.
1. Allow the tool to reach full speed before
1/8" WHEELS
touching the tool to the work surface.
2. Apply minimum pressure to the work
Clamp Nut
surface, allowing the tool to operate at
high speed. Grinding rate is greatest
when the tool operates at high speed.
3. Position yourself so that the open-
Backing Flange
underside of the wheel is facing away
from you.
4. Once a cut is begun and a notch is
established in the workpiece, do not
change the angle of the cut. Changing
the angle will cause the wheel to bend
and may cause wheel breakage. Edge
