Replacing Flap
Sandpaper/Brushes
To replace the flap sandpaper or brushes:
1. DISCONNECT SANDER FROM POWER!
2. While holding the outside end plate of the
flap sander, remove the arbor bolt and flange,
then remove the flap sander and place it
upright on a flat surface.
3. Remove the top end plate, then remove one
or two brushes to gain access to the retaining
bars that secure the sandpaper.
Note: All of the replacement sandpaper
needs to be oriented and installed so that
the abrasive side faces the same direction
and will face forward and down when the flap
sander is properly mounted on the machine.
4. Each retaining bar holds two 4
1
⁄2" x 6" pieces
of sandpaper. Loosen the two screws secur-
ing the retaining bar, then pull the old sand-
paper pieces away.
5. Cut two new pieces of sandpaper from the
selected grit, then slip them under the retain-
ing bar so that the abrasive side faces away
from the center of the flap sander, as shown
in Figure 21.
6. Make sure the sandpaper pieces are even
with one another and are centered in the
retaining bar, then re-tighten the retaining bar
screws to hold them in place.
7. If a flap brush is worn out or damaged, replace
it with a new one. Insert each brush into the
lower end plate and between two sandpaper
pieces attached to the same retaining bar, as
shown in Figure 22.

8. After replacing the sandpaper and positioning
the brushes, place the top end plate onto the
flap sander.
9. As you lightly push down on the top plate,
correctly position one brush to align with the
recessed slot in the top plate, then rotate the
flap sander and work on the one next to it.
Continue this process until all of the brushes
are correctly aligned and fully seated into the
top plate.
Note: When storing the flap sander in a dry,
protected place, secure the bottom and top
end plates with tie wraps or string so that the
end plates do not come loose and allow the
brushes to fall out.
