After sales service
Certain problems you can solve yourself by referring to the preceding What if …
chapter. First analyse the problem, then consult the chapter. If you don't find the
solution there contact the after-sales service. Prepare yourself properly. It will be
easier for the after-sales technician to diagnose the problem and judge if he should
come and look at the problem.
State the E no. and the S no. indicated on the
nameplate or - if it exists - the PNC (arrow) of the
after-sales service.
These figures will enable the after-sales service to
prepare a substitute, thus avoiding costs that would
arise from a pointless visit.
To have these numbers to hand we recommend that you note them
below:
E no./
PNC .....................................................................................................................
S no. ...................................................................................................................
If in spite of the instructions provided in the chapter What if … or as a result of usage
that does not conform with the functioning conditions set out in the user instructions
you call in the after sales service the labour and travel costs will not be covered by the
guarantee. So please strictly follow the instructions provided in the user instructions
