OPERATION INSTRUCTIONS
WARNING: To avoid injury from accidental start -
ups, turn switch OFF and remove the plug from
the power source outlet before making any ad-
justments.
INSTALLING HOOK AND LOOP SANDPAPER
1. Before installing sandpaper, make sure the hook
and loop fastener base is free of dust and dirt and
that the sander is unplugged with the ON/OFF
switch in the OFF position (2) .
2. The base blade (5) will hold any hook and loop
sandpaper without clamps or glue. Simply line up
the sandpaper with the hook and loop fastener
base and press together, making sure front edge
of the sandpaper is aligned with the front edge of
the hook and loop fastener base.
3. To remove used sandpaper, peel one edge away
from the hook and loop fastener base until the
whole sheet is free.
CAUTION: Do not use torn or severely
worn or damaged sandpaper. To do so could
damage the surface of the sanding base.
GENERAL OPERATING INSTRUCTIONS
1. Make sure that the power switch (2) is in the off
position, then plug in the tool.
2. Turn the switch ON (2) .
3. Do not use excess pressure while sanding and al-
ways sand in same direction as grain of wood. Let
the sandpaper do the work. Apply even pressure
over entire workpiece.
4. Check the wear on the sandpaper at regular in-
tervals and replace as necessary.
NOTE: Always turn the power switch OFF and
unplug the sander before changing sheets of
sandpaper.
5. For optimal sanding results on different materi -
als, you can set the desired sanding speed, and
always adjust speed (1) to grit size used. Before
starting a job, find the optimal speed (1) and grit
by testing out on spare material.
6. Empty dust box (4) regularly for optimal dust
pick-up performance.
EMPTY DUST: Press knob (3) downward and pull
it open, then pour out the dust.
NOTE: Do not use dust box when sanding met-
al. Do not clean the dust box by water.
7. When sanding is completed, remove the sand -
er from the workpiece and turn off the power
switch (2) .
8. When completely finished using the sander,
use a vacuum to dislodge all sand shavings and
dust, wipe with clean, soft cloth.
9. To prevent accidents, turn off the sander and
unplug it after use. Clean, then store the sand-
er indoors out of children’s reach.
SANDPAPER SELECTION
f
Choosing the right size, grit and type of sandpaper
maximizes the quality of your sanded finish. Alumi -
num oxide, silicon carbide, and other synthetic abra-
sives are best for power sanding as natural abrasives,
such as flint and garnet, are too soft for economical
use in power sanding.
f
In general, coarse grit will remove the most material
and finer grit will produce the best finish in all sand -
ing operations. The condition of the surface to be
sanded will determine the right grit for 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 the scratches left by the coarser grit while
a finer grit can be used for finishing. Always continue
sanding with each grit until surface is uniform.
NOTE: DO NOT use sander without sandpaper.
Doing so will damage the sanding base.
