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 DEWALT service centers and DEWALT 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).

USING SANDING BACKING PADS (FIG. 12)

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.

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 FIG.12 tool and work surface. The sanding

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.

5.Remove the tool from the work surface before turning the tool off. Allow the tool to stop rotating before setting it down.
