Conveyor belts should be maintained along with the frame holding the conveyor belt. The operator or maintenance personnel should be well versed with the basic maintenance of conveyor belt and its entire frame.
Good housekeeping is the key to longer conveyor belt. It is also advisable that a basic check list for conveyors be made and followed regularly.

The maintenance personnel should regularly walk around both the sides of the system and note the physical condition of the conveyor. Any unusual behaviour of moving components must be taken note of. Any material getting stuck has to be noted. Signs of misalignment or improper belt tracking have to be noted. Drive amperage requirements has to be checked and same thing has to be compared to previous levels for similar loads and conditions or adjusted to the manufacturers standard.

Few things that the operator can take care of are:
Only authorized personnel are allowed to operate the conveyor.
Operator should not run the conveyor when the motor guards are in position.
Before removing the material stuck, the conveyor should be stopped.
