during their regular service life. Nevertheless, certain checks have to be performed at regular
intervals:

Check the drum motor for visible damage every day.

Ensure daily that the belt is correctly aligned and centered to the drum motor as well as
parallel to the frame of the conveyor. Correct the alignment as necessary.

every week.
