The Model W1678 Double Drum Sander is designed
for rolls of 3" wide hook-and-loop sandpaper.
To change the sandpaper, do these steps:
1. Unplug the double drum sander!
2. Open the dust hood to expose the drums.
3. Observe the direction that the sandpaper is
wrapped around the drum, and unwind the
old sandpaper one drum at a time.
4. Use the old sandpaper as a pattern to cut out
the new sandpaper, or measure and cut the
sandpaper taper yourself. See Figure 56.
5. Tightly wrap the sanding drum with the new
sandpaper and keep the gaps to a minimum.
6. Apply two complete passes of
3
4" reinforced
strapping tape at both drum ends, making sure
that the second layer is directly on top of the
first.
7. Replace the sandpaper on the other drum,
and close and latch the dust hood.
