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 me-
chanical impacts including risk of burns,
•
hazards to the environment due to vapour-phase
hazardous substances,
•
risk of fire.
2.4 Safe working practices
The safety instructions given in these operating in-
structions, the applicable national accident preven-
tion regulations and any existing in-company work
instructions, operating and safety procedures issued
by the Operator must be followed.
2.5 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.
•
CAUTION During hand extruder operation (under
load), a voltage of not less than 230 V
1)
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.

2.1 Identification of information in the operating
instructions
In these operating instructions, safety instructions
whose non-observance may cause hazards to per-
sons are identified with
Hazard symbol according to DIN 4844 – W 9
for general hazards and with
Hazard symbol according to DIN 4844 – W 8
for electrical hazards.
Safety instructions whose non-observance may
cause damage to the hand extruder and its functions
are marked with
CAUTION
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 person-
nel must possess appropriate qualification for the
work to be performed. Functional and technical re-
sponsibilities and supervision of the operating per-
sonnel must be clearly regulated by the Operator.
Where the personnel do not have the necessary
skills and knowledge they must be trained and in-
structed (e.g. a DVS basic welder training in extru-
sion welding). A detailed instruction into hand ex-
truder operation will be provided by the Manufac-
turer/Supplier on request. Furthermore, the Operator
has to make sure that the contents of the operating
instructions is fully understood by the operating per-
sonnel.
