To change the paper:
1. Disconnect the machine from the power!
2. Lift the top cover and place a screwdriver as
shown in
Figure 18.
Figure 19. Sandpaper pattern.
5. Repeat Steps 2–4 on the opposite end of the
sanding drum, then remove the spring clips.
Note: Replace the paper on each drum
individually. Once the paper is removed the
drums can be slippery and hard to rotate.
6. Unwind the old sandpaper and use it as a
pattern, or use the pattern in
Figure 19, to
cut the sandpaper to the necessary shape.
7. Start with the left side of the drum, fold the
corner of the
sandpaper into the spring clip,
then install the clip onto the tension wheel.
Tap the clip with a hammer or mallet to
ensure it is seated.
Note: DO NOT pound the clip over the sand
-
paper. It is not necessary to drive the clip
completely on, just make sure it is secure.
Too much force will break the clip!
8. Tightly spiral the paper onto the drum, ensur-
ing there are no bubbles or overlapping
edges. Try to leave a uniform
3
⁄16" gap
between the spirals as you wind the paper
around the drum. This will allow the paper to
move and stretch slightly and will decrease
the likelihood of overlapping and tearing.
9. Fold the corner of the loose end into the
spring clip, then install the clip onto the ten
-
sion wheel on the right side.
10. Remove the spring tension tool from the ends
of the sanding drum to tension the paper.
11. Repeat Steps 2–10 for the other drum.

3. Rotate the sanding drum to stretch the ten-
sion spring. Slide the cap screw in the spring
tension tool into the head of the cap screw
securing the spring (see the inset box in
Figure 18), then place the spring tension tool
over the arm of the tension wheel as shown
in Figure 18.
4. Remove the screwdriver, then lightly tighten
the Phillips head screw in the spring tension
tool to secure it to the tension wheel.
