After a long period of time, adjustments may be necessary to
maintain the tension and tracking of the sanding belt. If the
belt will not hold its tension, tighten the set screw (G) Fig. 22.
If the belt will not hold its tracking, tighten the set screw (F)
Fig. 22. 

Make only small adjustments to these screws. Over-tightening
will lock the tension lever and/or the tracking knob.

NOTE:

1.

Loosen the table tilting lock handle (A) Fig. 23, move the stop (B) into position, and rotate the table (C) Fig. 24 until the
trunnion (D) Fig. 23 contacts the stop (B). Tighten the lock handle (A). 

NOTE:

The lock handle (A) is spring-loaded and can

be repositioned by pulling out the handle, moving it, and letting it spring back into position.

2.

Place a square (E) Fig. 24 on the table against the belt. See if the table is 90 degrees to the belt.

To adjust, loosen the table tilting lock handle (A) Fig. 23. Turn the adjusting screw (F) in or out until table is 90 degrees to
the belt.

5.

The adjusting screw (F) Fig. 23 ensures that the belt table can rapidly return to the 90 degree position after the table has
been tilted.
