4.
Upon completion of sanding
operation,
turn sander off and
wait
until sanding disc comes
to a complete stop before removing from workpiece.
5. Extended periods of sanding may tend to overheat the motor. If this occurs, turn sander
off and wait until sanding disc comes to a complete stop, then remove it from workpiece.
Remove sanding disc, then turn sander on and run it free without a load (off the workpiece)
to cool the motor.
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 tlnesander'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.
4. The condition of the surface to be sanded will
determiine
which grit will
do
the job.
5.
If the surface
is rough:
•
Start with a coarse grit and sand until the surface is uniform.
•
Then use medium to remove any scratches left by the coarse grit.
•
Then use a finer grit for finishingthe surface.
NOTE: ALWAYS continue sanding with
each grit
until
the
surface
is
uniform.
NOTE: DO NOT use the sander without sandpaper. This will damage the cushion.
