only by an authorized service center!
Checks and service work, as well as the replacement of light bulbs
or fuses must be performed by a specifically trained operator.
Information on the electrical system
Accident hazard due to electric current!
Touching live parts can cause serious injury or death.
► Only work on the machine when it is in a de-energized state.
► Before starting maintenance work on the electrical system:
- Park the machine securely
– see chapter 5 “Stopping and securing the machine” on page 5-17.
- Disconnect the battery connector
– see chapter 4 “Battery connector” on page 4-20.
- Check the insulation for damage.
Accident hazard due to high electrical voltages!
Improper performance of work on the electrical system can result in
serious injury or death.
► Maintenance that does not involve HV components (e.g. replacing
fuses), where the maintenance personnel must work near HV
components and, in the event of an error, could trigger an electrical
hazard, must be performed by "electrically trained persons". The
training must include the following factual information:
- the hazard sources on the machine,
- safety measures and
- the corresponding rules of conduct.
► In order to be permitted to perform maintenance on HV systems of the
machine, further training as "Expert for Work on HV Intrinsically Safe
Machines" (DGUV Information 200-005) is mandated in Germany. Be
aware of, observe and comply with the corresponding legal regulations
of other countries.
