SANDING
TIPS
1. DO NOT force
the sander.
The weight
of the sander
supplies adequate
pressure
on
the workpiece.
Let the sander
and the sandpaper's
grit do the work.
• Applying
additional
pressure
will only slow down the motor, wear the sandpaper
out faster and reduce the sander's
orbital speed.
• Excessive
pressure
will overload
the motor and cause
possible
damage
to the
sander
from the motor overheating.
. Excessive
pressure
will also result in a poor quality
finish.
2. Any existing finish or resin on wood may soften from the heat of the friction
and cause
the sandpaper
to load-up
faster.
3. Inspect sandpaper
frequently
and change
paper when grit is worn and not able to
perform
properly.
4. DO NOT sand in one spot for too long a time because
the sander's
rapid action
may
remove
too much material
and make the surface
uneven.
SELECTING
THE RIGHT
SANDPAPER
Selecting
the correct grit and type of sandpaper
is an extremely
important
decision
that
will allow you to achieve
the best quality sanding
finish.
1. Aluminum
oxide, silicon carbide
and other synthetic
abrasives
are best for power
sanding.
2. Natural
abrasives
such as flint and garnet
are too soft for economical
use in power
sanding.
3. Coarse
grit will remove
the most material and finer grit will give you the best finish
in all
sanding
operations.
