OPERATIONS

Paper Replacement

The Model W1772/W1773 is designed for 6" wide sandpa- per rolls.

To change the paper, do these steps:

1.DISCONNECT POWER TO THE SANDER!

2.Lift the top cover and place a screwdriver through the right side of the frame, as shown in Figure 29.

3.Rotate the sanding drum to stretch the tension spring. Fit the end of the spring tension tool shaft through the hole in the tension wheel arm (see Figure 29) and into the head of the cap screw secur- ing the spring.

4.Remove the screwdriver.

5.Repeat Steps 2–4on 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 30 to cut the sandpaper to the necessary shape, or see Figure 31 if using a dif- ferent width of sandpaper.

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 sandpaper. 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, ensuring there are no bubbles or overlapping edges, leaving a uniform 3/16" gap between the spirals as you wind the paper around the drum.

9.Fold the corner of the loose end into the spring clip, then install the clip onto the right tension wheel.

10.Remove the spring tension tool from the ends of the sanding drum to tension the paper, and repeat Steps 2–10for the other drum.
