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. 11)
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
5˚–10˚

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

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
(R) on the spindle.
2. Place the sanding disc (Q) on the backing
pad (R).
3. While depressing the spindle lock button, thread clamp nut (P) 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. 13)
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.
Coarse 16–30 grit
Medium 36–80 grit
Fine Finishing 100–120 grit
Very Fine Finishing 150–180 grit
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.
4. Move the tool constantly in a straight line
5˚–15˚

to prevent burning and swirling of work
surface. Allowing the tool to rest on the
work surface without moving, or moving
the tool in a circular motion causes
burning and swirling marks on the work
surface.
