ADJUSTMENTS
Diagonal Belt
Tracking
The diagonal belt tracking for your Model W1688 Edge Sander has been setup at the factory; how- ever, due to shipping or long use of the sander, the belt can begin to track diagonally. You can compensate for this normal condition by adjust- ing the roller support bracket. See Figure 30.
Keep your machine unplugged during all assembly, adjustments, or maintenance proce- dures. Otherwise serious personal injury may occur!
To adjust the diagonal belt tracking, do these steps:
1.Unplug the edge sander.
2.Loosen the belt tracking lock knob. See
Figure 31.
3.With the sander unplugged, loosen the two
4.While you rotate the sanding belt in the counterclockwise operating direction, alter- nately adjust the four Allen® set screws to tilt the idler roller and roller support bracket inward or outward in very small increments. See Figure 32. By tilting the idler roller this way, the belt will track horizontally.
5.When the belt tracking is not diagonal and is horizontal, tighten the the two cap screws. See Figure 32.
6.Tighten the belt tracking lock knob.
7.Rotate the belt a few more times to make sure the belt stays in the normal operating position. If it does not, repeat steps 1 through 7.
