guard must be positioned away from the operator. For deeper cutting with a Type 1
wheel, use a closed, Type 1 guard. Type 1 guards are available at extra cost from your
local dealer or authorized service center.
1. Allow the tool to reach full speed before touching the tool to the work surface.
2. Apply minimum pressure to work surface, to allow the tool to operate at high
speed.
3. Protect yourself during edge finishing by directing the open side of the guard
away from you.
4. Move the tool continuously in a forward and back motion to avoid creating
gouges in the work surface.
5. Remove tool from work surface before turning the tool off. Allow the tool to stop
rotating before setting it down.
WARNING: Do not use edge grinding wheels for surface grinding applications
because edge grinding 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 tool to work surface.
2. Apply minimum pressure to work surface, to allow the tool to operate at high
speed.
3. Maintain a 5 ˚ to 10 ˚ angle between the tool and
5 ˚ - 10 ˚
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 setting it down.
Mounting and Using Sanding Backing Pads
Sanding pads and sanding discs must be rated above minimum accessory speed as
shown on tool. Recommended sanding backing 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
CAUTION: Proper guard must be re-installed for

grinding wheel, sanding flap disc, wire brush, or wire
wheel applications after sanding applications are
complete.
1. Place or appropriately thread rubber backing pad
(L) down to spindle shoulder.
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 san ding 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 re moval 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 operate at high speed.
3. Maintain a 5
˚ to 15 ˚ angle between the tool and
5 ˚ - 15 ˚
work surface. The san ding disc should contact
approximately one inch of work surface.
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 surface without moving, or moving
the tool in a circular motion causes burning and swirling marks on the work
surface.
