USING SANDING BACKING PADS (FIG. 14)
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.
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 one inch 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.
5. Remove the tool from work surface before turning tool off. Allow
the tool to stop rotating before laying it down.
SURFACE FINISHING WITH SANDING FLAP DISCS (FIG. 12)
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
5˚-10˚

the tool and work surface.
4. Continuously move the tool in a
forward and backward 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.

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
