For best performance, the force measured on the gauge should be between the minimum and maximum values shown on the chart. If there is not enough deflection force, the belts should be tightened. If there is too much deflection force, the belts should be loosened.

6-2-3 Belt Replacement

Important!

It is very important to replace all belts at the same time.

If the drive belts have to be replaced, follow the procedure in Section 6-2-1 up to Step 6. Then release the belt from tension by fully unscrewing the tie rods. Slip off the belts, and replace them with new ones. Continue with the procedure for adjusting the belt tension.

6-3 Removal and Replacement of the Screen

NOTE: A qualified operator/maintenance mechanic should carry out this procedure.

1.Switch the machine off and lockout power by turning the disconnect switch to “OFF”, or remove the fuses from the main control pane.

2.Open the front panel.

3.Remove the bin.

∗The Deflection Force Value shown is for each belt and must be multiplied by the number of V-belt elements if all are deflected.
