Permissibility for Modifications

The machine must not be modified without HELLER's written approval. This applies particularly to fitting with additional equipment or conversions, welding on structural parts of the machine, functional modifications as well as modifications of safety equipment, for example the installation and the adjustment of safety devices and safety valves.

Fixtures

Hydraulic workpiece clamping fixtures have to be designed in accordance with the HELLER construction guideline.

Consequences of Unauthorized Modifications

Any modifications performed by the owner without written approval by HELLER will render warranty null and void for all parts affected by the modification. HELLER does not accept liability for any injury or damage resulting from unauthorized modifications.

On machines with EC marking, new evaluation due to the Machinery Directive becomes necessary after any modification which may reduce safety. The manufacturer's declaration of conformity or installation expires if the requirements of the machinery directive are no longer met.

Measures for Protection of Employees

All modifications require that the owner follows the applicable regulations for the protection of employees. In the EU member states, the Material/Tools For The Work Place Directive is decisive, and in Germany the "Betriebssicherheitsverordnung" (operational safety directive).

Handling

If lifting equipment is to be used to transport machine parts, the safety instructions relating to transport of the machine and its components must be adhered to.
