pads and sanding discs. Sanding flap discs are considered grinding
wheels by ANSI standards and require the use of a guard. (See

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.
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

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 to prevent burning and
