SAIIDPAPER SELECTION
S,e ecting the correct size and type sandpaper is an
ex:r'ernely important step in achieving a high quality
saMed f inish. Aluminum oxide, silicone carbide and
ctner synthetic abrasives are best for power san-
drng. Other natural abrasives, such as flint and
Eamet sandpaper are too soft for economica use in
power sanding. ln general. coarse grit * rernove
the most material and f iner grit '";il t'c,:-:€ lest
f inish in all sanding operatlons. The oonortron ci :ne
. surface to be sanded will determine which grit
sandpaper will do the job. lf the surface is rough,
start with a coarse grit paper sanding until surface is
-r ror-m. Medium grit paper may then be used to
rerr.,3re scratches left by the coarser paper and f iner
Enr ia"ier used f or f inishing of the surface. Always

MOTION SELECTION
The dual motion feature of your sander with its
readily accessible slide lever for quick motion
setting provides required motion for any sanding
application. lf your particular requirement is fast
cutting action for removing old f inishes, smoothing
rough wood, cutting stock down to required
dimensions or for sanding of surfaces to be painted,
orbital motion is best suited. For f ine f inish sanding
on work to be stained or varnished and for use with
polishing pad, straight tine motion is ideal.
