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