For service or repair work on pneumatic systems, disconnect the machine from the compressed air supply system (max. Exceptions to this are only adjustments and functions checks made by appropriately trained technicians. Work on the electrical equipment must be carried out only by electricians or appropriately trained persons. Work on parts and systems under electric current is not permitted, except as specified in regulations DIN VDE 0105. Conversion or changes to the machine must be authorized by us and made only in adherence to all safety regulations. Commissioning of the sewing head is prohibited until such time as the entire sewing unit is found to comply with EC directives.

All work on the electrical equipment of this sewing unit may only be carried out by qualified electricians or other appropriately trained persons. The mains plug must be pulled out. 5. 1 Connecting to the mains ­ Plug the mains cable into the socket. The nominal voltage indicated at the type plate and the mains voltage must correspond! 5. 3 Direction of rotation of the sewing motor The sewing unit is equipped with the newest step motor technology. It is not necessary to check the direction of rotation, this being set automatically by the control unit. 10 6. Pneumatic connection For the operation of pneumatic components, the sewing unit has to be supplied with anhydrous compressed air. For a trouble-free function of the pneumatic control procedures, the compressed air supply must operate as follows: Even at the moment of the highest air consumption, the minimum operating pressure must not drop below 6 bar. In case of important drop of the air pressure: ­ Increase the compressor output. ­ Increase the diameter of the compressed air hose. 2 3 2 1 Connecting the maintenance unit for compressed air ­ Connect the unit to the compressed-air supply with the connection hose 3 (Order no. Adjusting the operating pressure ­ The operating pressure is 6 bar. ­ Turn clockwise = increase pressure ­ Turn counter-clockwise = reduce pressure ATTENTION!No oil-bearing compressed air must be fed from the compressed air line. [. . . ] No oil-bearing compressed air must be fed from the compressed air line. The cleaned compressed air after the filter is used as blowing air for cleaning machine parts and for blowing workpieces out. Oil particles contained in the blowing air lead to malfunctions and stains on the workpieces. 11 7.
