Utilization 3.1 Commissioning Put the swivelling lever into operation only, if the installation and the electrical connection have been done correctly. 3.2 Normal operation - Use the swivelling lever in its intended application only. - Comply with the specifications on the data plate. 3.3 Inexpert handling - Ignoring the safety instructions and the operating instructions. - Not intended use. - Mounting of spare parts which are no original parts. - Violation against applicable law and standards. - 4. Maintenance and Servicing 4.1 Maintenance Inspect the swivelling lever about cleanness and smooth engagement in regular intervals. Define the intervals of the control depending on the ambient conditions and the frequency of use. 4.2 Servicing - Carry out repairs only when the swivelling lever is disconnected from the electrical supply before. - Damaged parts have immediately replaced with similar. - Until the complete restoration of the proper function the swivelling lever must not be used any more. - Use original spare parts only. - 5. Storage - Store the swivelling lever dry and dust-free. - 6. Disposal - The swivelling lever can be recycled. - The disposal applies to the valid environmental guidelines according to the location of the carrier and the local manufacturing conditions. - 04 SNS-BAG-04 08/22 © by MOLLET Operating instruction MOLLET D-74706 Osterburken Tel. +49 6291 6440-0 Fax +49 6291 9846Corel PDF Engine Version 23.1.0.389 CorelDRAW 2021
