6 Machine maintenance and cleaning
6.1 Denition of wear parts
The machine and the extra equipment are warranted for a pe-
riod of 24 months or 2000 operating hours, whatever comes
rst.
Thewarrantycoversdefectsinmaterialsorfabrication
as long as the regulations for using the machine in all docu-
ments are followed.
Of course, t
he war
ranty also covers wear parts as long as their
failure cannot be attributed to the function-related abrasion.
The wear parts that are mentioned below can already wear
down within the warranty period due to their normal func
-
tion. The average useful life of the wear parts can be seen in
the follo
wing table.
Use these values to determine operating costs, to plan your
spare part stock as well as to create individual maintenance
and service plans.
