Check that the old plates are level and that there are no negative steps between them that might damage the belt (see "Machine Check" in section "Manuals").
- First a visual check can be made to see if the trailing of the hot plates are dirty or not.
Also a straight edge can be used, sliding it from one hot plate to the next in board direction. There should be no interruption in the sliding action.
- If an out of level plate is found like in the photograph above, please get the customer to rectify the problem.
