Organizational Sequence of Maintenance and Repair Tasks

You supply the machine specifications, such as manufacturer, type, capacity, voltage, rotational speed, model, type of bearing, etc., as well as the potential damage. We prepare an offer comprising the respective scope of repair work. If you place your order, we draw up an inspection report after dismantling and testing the windings and mechanical parts.

Additional Scope of Work

In case other originally unknown damages on the machine are found during this inspection, which we think should be repaired, we draw up an additional offer. The decision regarding the execution of this additional repair work is made after consulting you.
