A good user manual

The lack of an instruction or false information given to customer shall constitute grounds to apply for a complaint because of nonconformity of goods with the contract.

Eventually, when one still can't find the answer to his problems, he will be directed to the Pfaff service. Lately animated manuals and instructional videos are quite popular among customers.
