Gib Adjustment

The gibs apply pressure to the slides of the sand- ing head (see Figures 32–33). This allows the sanding head assembly to accurately move up and down when using the elevation handwheel.

If the gibs are too loose, the sanding drum will deflect up during operation, which will result in poor sanding results.

If the gibs are too tight, it will be difficult to adjust the sanding drum elevation, which will cause excessive wear on the parts of the elevation sys- tem.

To adjust the gibs:

1.DISCONNECT SANDER FROM POWER!

2.Loosen the center lock nut on both gibs (see

Figure 32).

3.Adjust each of the six gib cap screws in or out in small, equal amounts, then rotate the elevation handwheel to test the sanding head movement.

Note: Tighten the cap screws to increase gib pressure.

4.Repeat Step 3 until you are satisfied with the sanding head movement, then re-tighten both lock nuts.
