commissioning within three weeks of its receipt. The customer expressly acknowledges that during the warranty period that 
extends beyond the length of the warranty period that is specified in the Commercial Code (the statutory warranty) s/he can 
neither require replacement of the product nor may s/he withdraw from the contract.

by an authorised person in possession of a valid certificate from the manufacturer. 

5.

 

Claims regarding a product defect that can be dealt with reasonably quickly and without additional consequences will be 
resolved  by  remedying  the  defect  (repair)  or  by  replacement  of  the  product  part  ,  because  in  such  a  case  it  is  a 
contradiction  of  the  standard  norms  that  the  entire  product  shall  be  replaced  (§  616,  paragraph  4  of  the  Commercial 
Code).
