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 inade-
quate maintenance.
CARE (carried out by user)
WARNING! Before carrying out any care or maintenance, the power supply – and, if
possible, all device connections – must be disconnected.
PLEASE NOTE! Improper care can lead to impairment of the device or even its destruc-
tion.
1. Housing surfaces must be cleaned with a clean, damp cloth. Make sure that no moisture can
penetrate the device.
2. Air inlets and outlets must be regularly cleaned of dust and dirt. If compressed air is used, make
sure 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.
