OPERATION
GENERAL SANDING
WARNING:
Finish sanding can
produce clouds of fine sanding dust that
could ignite in the presence of sparks or
an open flame. To avoid injury, always use
your sander in a well-ventilated area.
WARNING:
For your safety, and in
order to avoid damage, only turn the
sander ON and OFF when the sander is
contacting a surface.
1. Place the sander on the workpiece
BEFORE turning the switch to the ON
position. If the sander is started before
making contact with the workpiece,
the free-floating workpad may cause
scratches.
2. Sand using a circular or elliptical
motion while applying slight pressure.
3. Random orbit sanders can be moved
across the workpiece in any direction.
If you are sanding wood, you can
sand in any direction, regardless of
the grain of the wood.
4. The amount of downward pressure
will affect the rotation speed and the
sanding results:
a. Light pressure: recommended for
fine work.
b. Moderate pressure: recommended
for rough work.
c. Heavy pressure: not recommended;
does not allow the disc to rotate
properly.
5. Keep the sanding disc flat on the
workpiece. Using the edges of the pad
or tipping the sander may cause an
uneven finish, and may reduce the life of
the sanding pad.
6. Keep the sander moving in broad, even
strokes across the workpiece. Sanding
in one spot for too long may cause
gouging and uneven results.
7. Random orbit sanders work more
aggressively than simple orbital sanders.
Check your workpiece frequently.
8. Begin sanding with a coarser grit
sandpaper and gradually use finer and
finer grits until the desired finish is
achieved. Do not switch from a coarse
grit to a very fine grit in one step.
SANDING OPERATION
WARNING:
To avoid injury, always
unplug the sander before attaching or
removing sanding discs or the dust box.
1. Attach the sanding disc and the dust
box.
2. Place the sander on the workpiece,
and turn the sander ON.
3. Keep the sanding disc flat on the
workpiece and constantly moving
across the workpiece. Use long,
sweeping circular or elliptical strokes.
4. When you are finished sanding, switch
the tool OFF and wait until the sander
has come to a complete stop before
removing it from the workpiece.
REMOVING PAINT OR VARNISH
1. When removing several layers of paint
or varnish, remove as much as possible
with a paint or varnish remover.
2. Scrape the residue off with a putty
knife or scraping tool, and allow the
surface to cool and dry before sanding.
3. Select and install a coarse grit
sandpaper.
4. Keep the sander moving over new areas
in order to avoid heating and softening
the old coating.
5. Work in wide, overlapping strokes in
order to achieve a uniform finish.
6. As the workpiece begins to show through
the old coating, switch to a medium grit
sandpaper in order to avoid scratching
the surface. Gradually switch to a finer
grit until you achieve the desired finish.
