CARE, MAINTENANCE AND REPAIR
In order to ensure the long-term, proper functioning of the device, it must be regularly cleaned
and, if necessary, maintained. The maintenance requirement depends on the intensity of use and
the environment in which it is used.
We generally recommend a visual inspection before each operation. Furthermore, we recommend
carrying out all the applicable maintenance measures specified below once every 500 operating
hours or, in the case of a lower intensity of use, at the latest after one year. Warranty claims may be
limited in the event of defects resulting from inadequate maintenance.
CARE (carried out by user)
WARNING! Before carrying out any maintenance work, the power supply and, if
possible, all device connections must be unplugged.
PLEASE NOTE! Improper care can lead to impairment of the device or even de-
struction.
1. Housing surfaces must be cleaned with a clean, damp cloth. In doing so, ensure that no
moisture can penetrate into the device.
2. Air inlets and outlets must be regularly cleaned of dust and dirt. If compressed air is used,
care must be taken to ensure that damage to the device is prevented (e.g. fans must be
blocked in this case, as they could otherwise over-rev).
3. Lines and plug contacts must be cleaned regularly and dust and dirt must be removed.
4. In general, no cleaning agents or abrasive agents may be used, otherwise the surface finish
may be damaged.
5. Devices must generally be stored dry and protected from dust and dirt.
6. To ensure correct and safe operation, all accessible or removable lenses and light-emitting
apertures must be cleaned regularly.
MAINTENANCE AND REPAIR (by qualified personnel only)
HAZARD! There are live components in the device. Even after disconnecting the
mains connection, there may still be residual voltage in the device, e.g. due to
charged capacitors.
PLEASE NOTE! There are no user-serviceable components in the device.
PLEASE NOTE! Maintenance and repair work may only be carried out by sufficiently
qualified specialist personnel. If in doubt, consult a specialist workshop.
PLEASE NOTE! Improperly performed maintenance work may affect
warranty claims.
