against the soft mount.
2. Place wheel against the backing flange, centering the
wheel on the backing flange pilot.
3. While depressing the spindle lock button, thread the
clamp nut
18
on spindle, piloting the raised hub on
clamp nut in the center of grinding wheel.

4. Tighten the clamp nut with a wrench.
5. Reverse the above procedure to remove the wheel.
Surface Grinding with Grinding Wheels
(Fig. K)
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
worksurface.

20˚–30˚
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 wheel to stop rotating before laying the
tool down.
Edge Grinding with grinding Wheels
(Fig. L)
WARNING: Wheels used for cutting and edge
grinding may break or kickback 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 notching (less than 1/2" [13
mm] 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.
Refer to the Accessories Chart for more information.
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. Position yourself so that the open-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 grinding wheels
are not designed to withstand side pressures caused
bybending.
Fig. L
5. Remove the tool from the work surface before turning
the tool off. Allow the wheel to stop rotating before
laying the tool down.
WARNING: Do not use edge grinding/cutting wheels
for surface grinding applications because these wheels
are not designed for side pressures encountered
with surface grinding. Wheel breakage and serious
personal injury may result.
Surface Finishing with Sanding Flap
Discs (Fig. M)
1. Allow the tool to reach full speed before touching the
tool to the work surface.
2. Apply minimum pressure to work surface, allowing the
tool to operate at high speed. Sanding rate is greatest
when the tool operates at high speed.
3. Maintain a 5° to 10° angle between the tool and
worksurface.
5˚–10˚
Fig. M
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 wheel to stop rotating before laying the
tool down.
Mounting Sanding Backing Pads (Fig. N)
nOTE: Guard may be removed when using sanding
backingpads.
WARNING: Proper guard must be reinstalled for
grinding wheel, cutting wheel, sanding flap disc,
wire brush or wire wheel applications after sanding
applications are complete.
1. Place or appropriately thread backing pad
19
on
thespindle.
