before making adjustments.

• Check to see if the miter gage slot (A), shown in Figure 11, is parallel with the disc by placing a combination square in the miter gage slot with one end of the square against the disc as shown.

• Using a pencil, make a mark on the abrasive disc where the square contacts the disc.

• Rotate the disc 180° and check the distance between the disc and miter gauge slot at the opposite end of the table. If an adjustment is necessary, proceed as follows:

NOTE: When making the following adjustment, ensure the table locking wing nut is tightened.

• Using the supplied hex wrench, loosen the four screws

(B) indicated in Figure 12, which secure the table to the trunnions.

• Adjust the table by moving it in or out until the miter gage slot is equidistant from the disc at both ends of the table.

• Tighten the four screws securing the table to the trunnions.

To avoid trapping the work or fingers between the table and sanding disc, the table edge should be positioned a maximum of

1/16" from the sanding disc.
