OPERATION
PAPER PUNCH (Fig. 9)
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. 10)
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.
ORBITAL MOTION (Fig. 11)
Orbital motion is ideal for fast cutting action when removing
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.
WARNING
Collected sanding dust from sanding surface
coatings such as polyurethanes, linseed oil etc.
can self-ignite in your sander dust bag or
elsewhere and cause fire. To reduce the risk of
fire always empty your dust bag frequently while
sanding and never store or leave a sander without
totally emptying its dust bag. Also follow the
recommendations of the coatings manufacturers.

■
Unplug the sander.
WARNING
Failure to unplug the tool could result in
accidental starting causing possible serious
injury.
■
Slide the dust bag assembly onto the dust port on the
sander using a slight twisting motion.
TO EMPTY THE DUST BAG ASSEMBLY
For more efficient operation, empty the du

it i
s
no more than half full. Thi

empty and clean
the du
