E:
Where the sandpaper grits are
shown numerically, higher numbers
indicate finer grit and lower numbers
indicate coarser grit.
If the surface is rough, start with a coarse
grit and sand until the surface is uniform.
Medium grit may then be used to remove
scratches left by the coarser grit. Fine grit
should be used for finishing the surface.
Always continue sanding with each grit
until the surface is uniform.

Clamp or otherwise secure your workpiece
to prevent it from moving under the sander
while being sanded.Secure the workpiece
in a vice if possible.
WARNING:
Any unsecured
workpiece could be thrown toward the
operator causing injury.
Place the sander on the workpiece so the
complete sanding pad surface is in contact
with the workpiece. Turn the sander ON by
squeezing the trigger switch. Move the
sander slowly over the workpiece making
successive passes in parallel lines, circles
or crosswise movements. Because the
random orbital motion of the sanding pad
moves in tiny circles, it is not necessary to
move the sander with the grain or in the
same direction for successive passes
(Fig. 8).
