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 by
bending.
5. Remove the tool from the work surface before turning the tool off.
Allow the tool to stop rotating before laying it down.
WARNING: Do not use edge grinding/cutting wheels for surface
grinding applications if the wheel label has forbidden such use
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. 13)
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 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.

reinstalled for grinding wheel, sanding flap
disc, wire brush or wire wheel applications
after sanding applications are complete.
1. Place or appropriately thread backing
pad (O) on the spindle.
2. Place the sanding disc (P) on the
backing pad.
3. While depressing spindle lock, thread
the clamp nut (E) 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 pad while depressing the spindle lock button.
USING SANDING BACKING PADS (FIG. 15)
Choose the proper grit sandpaper for your application. Sandpaper
is 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.
