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 by bending.
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.

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
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 wheel to
stop rotating before laying the tool down.
MOUNTING SANDING BACKING PADS (FIG. 14)
NOTE:
Guard may be removed when using sanding backing pads.
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 (S) on the

spindle.
2. Place the sanding disc (T) on the backing pad (S).
3. While depressing the spindle lock button, thread
clamp nut (R) on spindle, piloting the raised hub on
the clamp nut into the center of san ding disc and
backing pad.
4. Tighten the clamp nut by hand. Then depress the
spindle lock button while turning the sanding disc
until the sanding disc and clamp nut are snug.
5. To remove the wheel, grasp and turn the backing
pad and sanding disc while depressing the spindle lock button.
USING SANDING BACKING PADS (FIG. 15)
Choose the proper grit sanding discs for your application. Sanding discs are available
in various grits. Coarse grits yield faster material removal rates and a rougher finish.
Finer grits yield slower material removal and a smoother finish.
Begin with coarse grit discs for fast, rough material removal. Move to a medium grit
paper and finish with a fine grit disc for optimal finish.

1. Allow the tool to reach full speed before touching 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 15° angle between the tool and work surface. The san ding disc
should contact approximately 1" (25.4 mm) of work surface.
