CONVEYOR BELT TRACKING ADJUSTMENT

The conveyor belt should track in the center of the conveyor table. Occasionally check the belt tracking by running

the conveyor belt at high speed for a few minutes. If the belt shifts to one side or the other, the belt tracking needs

to be adjusted. NOTE: Do not allow the belt to track off the rollers as this may damage the belt.

1. If the belt tracks to the left (viewing from the infeed side), tighten the left side tensioning screw by rotating it clock-

wise while holding its nut in place. This will make the belt shift to the right side.

2. If the belt tracks to the right (viewing from the infeed side), tighten the right side tensioning screw by rotating it

clockwise while holding its nut in place. This will make the belt shift to the left side.

3. Let the conveyor belt run for a few minutes to check the belt tracking. Re-adjust as necessary.

NOTE: The tracking adjustments may not be apparent immediately. Make small corrections of approximately

1/4 turn increments to the tensioning knob and evaluate the results. Re--adjust as necessary until the belt is tracking

properly.

CONVEYOR BELT TENSION ADJUSTMENT (Fig. 15)

The conveyor belt tension should be properly adjusted to ensure safe operation and protect the belt from damage.

The belt tension can be adjusted by rotating the tensioning screws on both sides of the conveyor table. To adjust

the belt tension:

ADJUSTMENTS

1. Turn off and disconnect the machine from the power source.

2. Release the belt tension equally on both sides of the table by

holding the hex nuts (Fig. 15 - 1) in place while rotating the tension-

ing screws (Fig. 15 - 2) counterclockwise. Position the belt in the

center of the rollers.

3. Adjust the tensioning screws so that the end of both tensioning

screws extend about 1/4” beyond the hex nuts (Fig. 15 - 1).

4. To tighten the belt tension, rotate the tensioning screws clock-

wise in small increments until the belt no longer slips on the rollers.

To loosen the belt tension, rotate the tensioning screws counter-

clockwise.
