OPERATION
WARNING
Your sander should never be connected to power
supply when you are assembling parts, making
adjustments, assembling or replacing sandpaper,
cleaning, or when not in use. Disconnecting
sander will prevent accidental starting that could
cause serious personal injury.
INSTALLING ADHESIVE SANDPAPER (Fig. 5)
Inspect sandpaper before installing. DO NOT use if
broken of defective.
INSTALLING ADHESIVE (HOOK& LOOP)
SANDPAPER
Unplug the sander.
■
Align holes in hook and loop type sanding disc with
■
holes in pad, then carefully press fuzzy side of
sanding disc against pad as tightly as possible.
Note: Hook and loop type sanding discs can be
reused for the life of the sanding abrasive. It is
recommended that you keep the sanding disc backing
pad clean to provide for best adhesion. Clean
occasionally by brushing lightly with a small brush.
WARNING
Failure to unplug your sander could result in
accidental starting causing possible serious
personal injury.
INSTALLING NON-ADHESIVE SANDPAPER
Unplug the sander.
■
If replacing sandpaper, remove old sandpaper.
■
To remove paper, release paper clamp by lifting up on
lever, and disengaging it from the tab, and allowing
the lever to lower.
Insert end of new 1/4 sheet sandpaper approximately
■
12.7 mm under the paper clamp.
Note: 12.7 mm clamping of sandpaper is necessary
for multi-sheet stacking of paper.
Lift up on lever and lock into place. Apply downward
■
pressure to conform sandpaper to base.
Wrap sandpaper around cushion. Lift lever on
■
opposite end of sander and insert loose end of
sandpaper under paper clamp. Fit sandpaper tight
against cushion.
Lift up on lever and lock into place.
■
Multiple sheets of sandpaper can be installed at one
■
time for convenience.
PAPER PUNCH (Fig. 6)
A paper punch template has been supplied with your sander
for aligning and punching holes in sandpaper. The punched
holes must align with the holes in the sander cushion.
Install sandpaper on your sander.
■
Align sander cushion over the paper punch.
■
Push down on sander
■
SANDPAPER SELECTION
Selecting the correct size grit and type sandpaper is an
extremely important step in achieving a high quality
sanded finish. Aluminum oxide, silicon carbide, and other
synthetic abrasives are best for power sanding. Natural
abrasives, such as flint and garnet are too soft for
economical use in power sanding.
In general, coarse grit will remove the most material and
finer grit will produce the best finish in all sanding
operations. The condition of the surface to be sanded will
determine which grit will do the job. If the surface is
rough, start with a coarse grit and sand until the surface
is uniform. Medium grit may then be used to remove
scratches left by the coarser grit and finer grit used for
finishing of the surface. Always continue sanding with
each grit until surface is uniform.
Note: DO NOT use sander without sandpaper. Doing so
will damage the cushion.
PREPARING FOR OPERATION
CAUTION
Be careful not to let your hand completely cover
air vents.
SANDING (Fig. 1)
WARNING
Unsecured work could be thrown towards the
operator causing injury.
Hold your sander in front and away from you, keeping it
clear of the workpiece. Start your sander by pressing the
switch button to "ON" position and letting the motor build
to its maximum speed. Gradually lower your 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 adequate
pressure, so let the sandpaper and sander do the work.
Applying additional pressure only slows the motor, 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 or resin on 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.
WARNING
Do not wear loose clothing or jewellery when
operating sander. They could get caught in
moving parts causing serious injury. Keep head
away from sander and sanding area. Hair could
be drawn into sander causing serious injury.
