sand in same direction as the grain of the wood. Let
the sandpaper do the work. Apply even pressure
over the entire workpiece.
f
Check the wear on the sandpaper at regular intervals
and replace as necessary.
NOTE:
Always turn the switch OFF and unplug
the sander before changing sheets of sandpaper.
f
Empty dust box

switch and remove the sander from the workpiece.
f
When completely finished using the sander, use a
vacuum to dislodge all sand shavings and dust. Wipe
with a clean, soft cloth.

SANDPAPER INSTALLATION
f
WARNING:
To avoid injury from accidental startups,
turn switch OFF and remove the plug from the pow
-
er source outlet before making any adjustments.
f
Before installing sandpaper, make sure the hook
and loop fastener base is free of dust and dirt and
that the sander is unplugged.
f
The hook and loop fastener base 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.
f
There are also provided clamps
(5)
to fasten non-
hook-and-loop sandpaper to the sander. Select a
sandpaper with the correct grit corresponding to
the work to be carried out. To take maximum advan
-
tage of the sander’s high removal rate and smooth
finishing. It is essential that the sandpaper be prop
-
erly and tightly secured. Tight paper also wears less
and lasts longer. Insert end of new 1/4 sheet sand
-
paper approximately 1,5cm under the paper clamp.
Lift up on paper clamp lever and lock into place.
Apply downward pressure to conform sandpaper to
sanding base. Wrap sandpaper around cushion. Lift
lever on opposite end of sander and insert loose end
of sandpaper under the paper clamp. Fit sandpaper
against cushion tightly. Lift up on the lever and lock
into place.
f
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 hook and loop fastener base.
SELECTING THE SANDING SHEET
Depending on the material to be worked and the
required rate of material removal, different sanding
sheets are available:
