ADJUSTING THE TENSION AND TRACKING OF THE SANDING BELT
Your machine is shipped without belt tension. Before operating the machine, tension the belt properly
and ensure that the belt is tracking correctly.
Disconnect the machine from the power source!
1. Loosen the two lock knobs (A) Fig. 39 and remove the top cover (B).
2. Turn the belt tension handle (C) Fig. 40 counter-clockwise to increase belt tension. Correct tension is determined
by its flatness on the platen with just enough tension to take the curl out of the belt.

3. Rotate the belt by hand and tighten or loosen the tracking knob (E) Fig. 41 until the belt is running true on the
pulleys.
4. Jog the machine "ON" and "OFF" to confirm that the belt is tracking properly. If the belt moves toward either side,
turn the tracking knob (E) Fig. 41 clockwise to direct the belt toward the adjusting screw or counter-clockwise to
direct it in the opposite direction.
5. You can make your final adjustment with the motor running. This adjustment is usually very slight. After the belt is
tracking properly, disconnect the machine from the power source, and replace the top cover.

NOTE: After a long period of time, you may have to make adjustments to the tension and tracking of the sanding belt.
If the belt will not hold its tension, tighten the set screw (G) Fig. 42. If the belt will not hold its tracking, tighten the set
screw (F) Fig. 42. Make only small adjustments. Over-tightening will lock the tension lever and/or the tracking knob.
