for electrical hazards.
Safety instructions whose non-observance may cause damage to the hand extruder and its
functions are marked with
Instructions directly indicated on the hand extruder must be strictly followed and kept in a fully
legible state.
2.2

Personnel qualification and training

The operating, maintenance and inspection personnel must possess appropriate qualification for
the work to be performed. Functional and technical responsibilities and supervision of the oper-
ating personnel must be clearly regulated by the Operator. Where the personnel do not have the
necessary skills and knowledge they must be trained and instructed (e.g. a DVS basic welder
training in extrusion welding). A detailed instruction into hand extruder operation will be provided
by the Manufacturer/Supplier on request.
Furthermore, the Operator has to make sure that the contents of the operating instructions is ful-
ly understood by the operating personnel.
2.3

Risks resulting from non-observance of the safety instructions

Non-observance of the safety instructions may cause hazards to persons and the environment
or damage to the hand extruder. Moreover, failure to observe the safety instructions may lead to
the forfeiture of any damages.
Non-observance of the safety instructions may in particular involve the following risks:
• failure of important hand extruder functions,
• hazards to persons due to electrical and mechanical impacts including risk of burns,
• hazards to the environment due to vapourphase hazardous substances,
• risk of fire.
2.4

Safety instructions for Operator / operating personnel

• Before placing the hand extruder in service, check the mains voltage and frequency against
the data indicated on the type tag. The allowable tolerances are ± 5 % for voltage and/or ±2
% for frequency.
• According to VDE 0100 §55, the hand extruder must be operated via a residual current-
operated circuit breaker or an isolating transformer.
• During hand extruder operation (under load), a voltage of not less than 230 V
must be available at the connector of the hand extruder.
When using an extension cable, make sure to observe the minimum conductor cross-section.
Use extension cables with protective conductor only.
