if cracks, tears or cracks appear on the surface
of the belt or if the belt is so worn by operation that it can no longer be tightened with the tension pulleys.
The factory adjusting of the tension pulleys must be checked after app. first 5 hours of operation when the belt has been run
in, to prevent belt damage due to its elongation and insufficient tensioning by it tension pulley.
If you are not sufficiently manually skilled, have the operations done by an authorised service centre.
