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 injury may result.
SURFACE FiNiSHING WITH SANDING FLAP DISCS
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 5o_10°
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.

USING SANDING BACKING PADS
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 materi-
al 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
