Maintenance and Repair

Cleaning and Servicing
Danger! Electric voltage! Operations in the vi‐
cinity of live parts are extremely dangerous.
WARNING
Work required on the electric system may only be carried out
by skilled electricians. Tools for electricians (VDE tools) are
absolutely necessary.
Prior to commencing work:
1. Isolate (even auxiliary circuits).
2. Protect the system or plant against restart.
3. Ensure de-energization.
4. Ground and short-circuit.
5. Cover or shield any adjacent live parts.
Maintenance work during ongoing operation
may result in personal injury and material
damage!
WARNING
Do not carry out any maintenance measures while the ma‐
chine is running.
During maintenance work, protect the system against re‐
starting and unauthorized use.
Hot surfaces with temperatures over 70 °C
may cause burns!
CAUTION
Allow the motors to cool down prior to commencing work.
Wear safety gloves.
Do not work on hot surfaces.
Motors
Excessive dirt, dust or chips may adversely affect the functionality of the mo‐
tors and, in extreme cases, even cause a failure of the motors. Clean the
cooling fins of the motors at regular intervals (after one year at the latest) to
reach a sufficiently high heat emission surface. If the cooling fins are partially
covered with dirt, sufficient heat dissipation via the ambient air is no longer
ensured.
Connection cable
Contact with live parts may cause death by
electrocution!
WARNING
Change damaged connection cables and decommission
the plant immediately.
Do not repair any connection lines provisionally.
●
Check connection cables for damage at regular intervals and replace
them, if necessary.
