19. Compressed air

Note!
Switch off the power supply.
Caution!
The entire compressed air system must always be
depressurised.
• Clean the machine, at least the work area, in the
prescribed manner.
• Regularly check all compressed air lines, hoses and screw
connections for leaks and externally visible damage.
• Carefully detach hoses. Escaping compressed air may swirl
up dust.
• Protect air connections to prevent them from getting dirty.
• Never mix up connections, plugs or switches. This will
inevitably result in malfunctions

20. Electrical work

Work on the electrical equipment must only ever be
performed by a qualified electrician.
• Before attempting any work on the electrical equipment
or in the immediate vicinity of live electrical operating
equipment, instruct a qualified electrician to isolate and
reliably disconnect the machine from the power supply
and earth it.
• Before attempting any work on electric drives, devices and
operating equipment always make sure they are dead.
Danger!
When operating electric devices or after connecting
them to the power supply, specific parts of devices
or operating equipment automatically carry a
dangerously high level of voltage.
Always immediately instruct a qualified electrician to
replace damaged and worn-through cables as well as loose
or unsealed cable connections on the machine.
Only use genuine replacement fuses of the prescribed
amperage. Instruct a qualified electrician to check the
electrical equipment if fuses frequently blow.
• Unauthorised persons must be prevented from entering
the work area while these measures are being carried out.
• Failure to observe the safety provisions or DIN, EN or VDE
regulations and / or lacking specialised knowledge may
result in serious damage and / or material damage when
touching or working on electrical devices / operating
equipment.
