Abrasive Paper Installation

Disconnect machine from power source.

Proper attachment of the abrasive strips to the drums is important for achieving top performance from the sander.

See page 38 for a list of available abrasive strips with their respective grits and some tips on choosing the proper strip for a particular job. If using different size grits simultaneously, always place the coarser grit on the front drum.

Attach the abrasive paper as follows:

1.Open the hood by removing the handwheel and turning the two locking handles at the front counterclockwise.

2.Remove the socket head cap screw and locking wedge (Fig. 8) from both ends of the drum.

Note: If the wedge sticks, use a flat head screwdriver as leverage to free it.

3.Cut a length of the Ready-To-Cutabrasive strip (14'-9" for the DDS-225, 21'-3" for the DDS-237). This will be enough to cover one drum.

Note: The taper on the remaining roll can later be used for the starting edge of your next strip.

4.Mark and cut a taper at the right end of the abrasive strip (Fig. 9). Because the tapered end should use all of the recess at the right side of the drum, its end must be trimmed back leaving an edge of about 1/2 inch, as shown. Now trim the left side of the abrasive paper in a similar manner (Fig. 10).

Note: An alternate method of tapering the ends of the abrasive strip is to place the removed sandpaper strip on top of the new strip and to use this as a template.

5.Begin at the right end of the drum and tuck the tapered right end of the abrasive roll into the recess (Fig. 8). Place the locking wedge into the recess and tighten firmly with the socket head cap screw.

6.Begin wrapping the strip around the drum, keeping it taut as you go. The tapered cut of the strip should follow the right edge of the
