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 adjust-
ments.
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 (4) .
2. The base blade (3) will hold any hook and loop
sandpaper without clamps or glue. Simply line
up the sandpaper with the hook and loop fas-
tener 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 dam-
aged sandpaper. To do so could damage the surface
of the sanding base.
GENERAL OPERATING INSTRUCTIONS
1. Make sure that the power switch is in the off
position, then plug in the tool.
2. Turn the switch ON.
3. Do not use excess pressure while sanding and
always 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 ma -
terials, you can set the desired sanding speed,
and always adjust speed (1) to grit size used.
Before starting a job, find the optimal speed
and grit by testing out on spare material.
6. Empty dust box (2) regularly for optimal dust
pick-up performance.
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.
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 sandpa-
per maximizes the quality of your sanded finish.
Aluminum oxide, silicon carbide, and other syn-
thetic abrasives 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 mate-
rial and finer grit will produce the best finish in all
sanding 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.
MAINTENANCE
Regular inspection and cleaning reduces the ne -
cessity for maintenance operations and will keep
your tool in good working condition. The motor
must be correctly ventilated during tool opera-
tion. For this reason avoid blocking the air inlets.
ENVIRONMENTAL PROTECTION
Recycle raw materials instead of disposing as waste.
