Mounting and Using Sanding
Backing Pads
Sanding pads and sanding discs must be rated above minimum
accessory speed as shown on tool. Recommended sanding back-
ing pads and sanding discs are available at extra cost from
D
E
WALT service centers and D
E
WALT dealers.
NOTE: Guard may be removed for sanding applications with
backing pads and sanding discs. Sanding flap discs are considered
grinding wheels by ANSI standards and require the use of a guard.
(See Mounting and Using Depressed Center Grinding Wheels and
Sanding Flap Discs).
MOUNTING SANDING BACKING PADS
Turn off and unplug tool before making any adjustments or
removing or installing accessories. Before reconnecting the
tool, depress and release the trigger switch to ensure that the
tool is off.
CAUTION: Proper guard must be re-installed for grinding wheel,
sanding flap disc, wire brush, or wire wheel applications after sand-
ing applications are complete.
1. Place or appropriately thread rubber backing
pad (L) down to soft mount.
2. Place the sanding disc (M) on the rubber
backing pad (L).
3. While depressing spindle lock, thread clamp
nut (N) on spindle, piloting the raised hub on
the clamp nut into the center of sanding disc
and backing pad.
4. Tighten the clamp nut with the proper
wrench.
5. To remove the wheel, reverse the above procedure.
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 material
removal and a smoother finish.
Begin with coarser 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 work
surface.
2. Apply minimum pressure to work surface, allowing tool to oper-
ate at high speed.
3. Maintain a 5˚ to 15˚ angle between the tool
and work surface. The sanding disc should
contact approximately one inch of work sur-
face.
4. Move the tool constantly in a straight line to prevent burning and
swirling of work surface. Allowing the tool to rest on the work sur-
face without moving, or moving the tool in a circular motion
causes burning and swirling marks on the work surface.
5. Remove the tool from the work surface before turning the tool
off. Allow the tool to stop rotating before setting it down.
