Safety instructions for maintenance, inspection and mounting

The Operator is responsible for ensuring that maintenance, inspection and mounting activities
are performed by authorized and qualified personnel who are thoroughly familiar with the op-
erating instructions.
• As a rule, the hand extruder must be shut off and the connector unplugged before proceed-
ing to any work on the unit. The shutoff procedure for the hand extruder described in the op-
erating instructions must be strictly observed.
• Electrical hazards must be ruled out (for details, see VDE guidelines and the standards of
your local electric utility, for instance)
VDE 0701 (IEC 335) prescribes the measurement of the protective conductor re-
sistance, insulation resistance and leakage current after each repair or modification to
electrical equipment. Furthermore, a visual inspection of the unit and its connecting
cable as well as voltage and current measurements and a function test must be
carried out.
• Ensure the safe and environmentally compatible disposal of media, auxiliary materials and
replaced parts!
• Remount and reactivate all safety and protective devices immediately on completion of the
maintenance, inspection or repair work.
2.7

Unauthorized modifications and spare parts

Modifications or changes to the unit are only allowed after consultation with the Manufacturer. In
the interest of safety, only original spare parts and accessories authorized by the Manufacturer
should be used. The use of components other than the original spare parts may invalidate the
Manufacturer's liability for any resulting damage.
