5.1 The customer must accept the service Immediately after completion thereof (assembly, repair or similar).

5.8 Only if operational safety is endangered or disproportionately serious damage is imminent will the customer be entitled to remedy a defect itself or have it remedied by a third party and to demand reimbursement of costs from the contractor, where a reasonable period of notice must be offered to the contractor in this event.
5.9 The costs of remedying substantiated complaints of defects will be borne by the contractor insofar as this does not impose a disproportionate burden on it.

6. Liability and disclaimer

6.1 The contractor will be liable for damage to the object of the service only up to the amount of the agreed price for the service. The contractor has the choice of repair, resupply or replacement at its own expense.
