Installing or removing abrasive paper
For conventional type of abrasive paper with pre-
punched holes (standard equipment) (Fig. 2):
Turn the clamp lever counterclockwise. Insert the paper
end into the clamper, aligning the holes in the paper with
those in the pad. Then return the clamp lever to the
original position to secure the paper. Repeat the same
process for the other end of the tool, maintaining the
proper paper tension.
For conventional type of abrasive paper without pre-
punched holes (accessory) (Fig. 3):
Turn the clamp lever counterclockwise. Insert the paper
end into the clamper, aligning the paper edges even and
parallel with the sides of the base. Then return the clamp
lever to the original position to secure the paper. Repeat
the same process for the other end of the tool,
maintaining the proper paper tension.
Place the punch plate (optional accessory) over the paper
so that the guide of the punch plate is flush with the sides
of the pad. Then press the punch plate to make holes in
the paper.
For hook-and-loop type of abrasive paper with pre-
punched holes (accessory) (Fig. 4):
Remove all dirt or foreign matter from the pad. Attach the
paper to the pad, aligning the holes in the paper with
those in the pad.
CAUTION:
• Never use pressure-sensitive abrasive paper.
