Warranty and liability

The manufacturer warrants that the supplied product is free of material
and manufacturing defects, and undertakes to repair or to replace any
defective parts without charge.
The guarantee period for devices is 24 months. Upon conclusion of a
maintenance contract within the first 6 months after purchase, the
guarantee period extends to 60 months.
For defects to which the lack of assured properties also counts, the
supplier is liable with exclusion of further claims as follows: All those
parts that, within the guarantee period calculated from the day of the risk
transfer, can be demonstrated as a result of circumstances prior to the
risk transfer, in particular due to defective design, inferior materials or
defective execution, to be unusable or whose usability is significantly
impaired, are improved or replaced in accordance with the choice of the
supplier free of charge. The identification of such defects must be
notified to the supplier immediately, however at the latest seven days
after the identification of the fault, in writing. If the customer omits this
notification, the performance is considered approved despite the defect.
Further liability for indirect or direct damages does not exist. If device-
specific maintenance or inspection work prescribed by the supplier is to
be performed within the guarantee period by the customer
(maintenance) or by the supplier (inspection) and these requirements
are not met, claims for damages that result from non-observance of
these requirements are void.
Further claims, in particular for consequential damages, cannot be made
valid.
Wear parts and damages that arise through improper handling, incorrect
installation or non-regulatory use are excluded from this clause.
