OPERATING
THE SANDER
See Figure 7.
Clamp or otherwise secure the work to prevent it from
moving under the sander.
_IL WARNING: Unsecured work could be thrown
towards the operator causing injury.
Hold the sander in front and away from you, keeping it
clear of the workpiece. Start the sander by sliding the
switch to the ON ( I ) position and letting the motor build
to its maximum speed. Gradually lower the sander on the
work with a slight forward movement. Move it slowly using
forward and backward strokes.
DO NOT FORCE. The weight of the unit supplies ad-
equate pressure, so let the sanding sheet and sander do
the work. Applying additional pressure only slows the mo-
tor, rapidly wears sandpaper and greatly reduces sander
speed. Excessive pressure will overload the motor causing
possible damage from motor overheating and can result
in inferior work. Any finish on resin or wood may soften
from the frictional heat. Do not allow sanding on one spot
too long as the sander's rapid action may remove too
much material, making the surface uneven. Always lift the
sander from workpiece before turning off.
Flush sanding can be performed with the sander. The
front edge of the sander allows flush sanding in corners.
The two side edges can also be used when sanding in
corners. Always remove sander from workpiece before
turning the sander off.
ON
ORBITAL MOTION
Orbital motion is ideal for fast cutting action when remov-
ing old finishes, smoothing rough wood, cutting stock
down to required dimensions or for finishing surfaces to
be painted. The sandpaper moves in tiny circles at a very
high speed, allowing the sander to move easily.
REMOVING SANDPAPER BEFORE STORAGE
Do not store the sander with sandpaper installed. Heat
generated from sanding causes the pressure sensitive ad-
hesive to flow and form a tight bond between the cushion
and sandpaper.
Removing the sandpaper soon after you have finished a
sanding operation avoids letting the adhesive set up. If the
sandpaper is left on the cushion for an extended period
of time after use, the adhesive will set up and cause the
sandpaper to become difficult to remove. It may also tear
when removing. When this situation occurs, it becomes
difficult to clean the cushion for the next sheet of
sandpaper.
NOTE: If you forget to remove the sandpaper after a
sanding operation, sand for a few minutes to soften the
adhesive backing before attempting to remove sandpaper.
