months. However, the belts may need to be changed more or less frequently, depending upon system use.

To replace the conveyor belts:
CAUTION! This procedure should only be performed by a trained service
technician.
1. Perform a service shutdown, see 2.11 Service Shutdown.
2. Open the front door.
3. Push the gripper assemblies toward the chamber, providing access to the conveyor.
4. Loosen the belt tensioner screw located on the tension pulley tire (Figure 8-4).
5. Slide the tension pulley tire to the right to reduce tension and provide slack in the belt.
6. Remove the old belt from all pulley tires and discard.
7. Using isopropyl alcohol and a soft cloth or cotton swabs, clean all metal surfaces that make
contact with the belt, including pulleys and rails.
8. Compare the new belt to the one remaining on the other rail to determine its proper
orientation.
9. Loop the new belt around the pulley tires at the opposite end from the motor (Figure 8-4).
Continue to loop from one end of the conveyor rail and extend it toward the motor end.
10. Loop the conveyor belt around the two pulley tires on the tensioner.
11. Reposition the tension pulley tire and belt securely in place while tightening the screw with
a 4 mm hex key. Torque the screw to 87 in-lbs (1.0 kg-m).
12. When both conveyor belts have been replaced, power on the system.
13. Open the Maintenance screen and enable manual mode, see 6.7 Manual Mode.
14. Click on the conveyor tab and run both Lane 1 and Lane 2 motors manually to test the
conveyor belts.
„ The conveyor belts should move smoothly with no slipping on their pulleys.
