Dewert User Manual Heavy-Weight Tables – Updated 11.2021/3 MDR Page 9 of 14
Important:
At tables with hydraulic height adjustment as well as for the gas springs, wipe the piston rod with a soft cloth
at regular intervals. This prevents dust from entering through the dust lip and preserves the service life of the
unit.
Caution:
When cleaning, secure the table against unintentional lowering of the lying surface.
To do so, place the head part horizontally and disconnect the power plug from the mains socket.
The power plug must not come into contact with water or cleaning agents.
The electrical components must not display any external damage through which liquid could enter. Do not
clean the table with water jets, a high-pressure cleaner or with a so-called bed washer. Only use moist cloths.
6. Maintenance and technical inspection
The device has been designed and manufactured in such a way that it will operate safely over a very long
period of time if used as intended and in a correct manner. Depending on the conditions of use, place of use
and care, the expected operating service life is 10 years or 100,000 drive cycles (double stroke = 1x up and
down).
Regular maintenance procedures
are required to ensure patient, user and product safety. They must be
carried out every two years at the latest.
The maintenance procedures can be carried out by qualified personnel/instructed personnel.
The scope of maintenance includes, for example:
•
Thorough visual inspection of all components, especially motor and switch with mains supply line or
hydraulic system
•
Check all swivel joints for completeness.
•
Check proper fit of the screw connections.
•
Lubricate the swivel joints and operating levers slightly with low viscosity spray oil, if necessary.
•
Lubricate the roller guides with a little bearing grease or similar using a brush, if necessary.
Insufficient lubrication is noticeable through noise development.
A checklist for maintenance/technical inspection can be found in the appendix.
In addition to maintenance in accordance with the legal requirements of DGUV Regulation 3 / IEC
62353, a technical inspection must be carried out every two years at the latest on tables with
electromotive adjustment.
This technical inspection may only be carried out by authorised and trained specialists.
A checklist for maintenance/technical inspection can be found in the appendix.
Despite regular maintenance/technical inspection, the
user
is also responsible for patient safety and proper
and reliable functioning. As the user, make sure that the table is in good working order prior to each use
(visual inspection). In the event of any abnormalities, take the table out of service immediately and inform the
operator.
Replace damaged or worn components immediately and do not use the table until it has been repaired.
The table complies with the safety regulations prescribed at the time it was placed on the market. Improper
repairs and structural modifications (disassembly of original parts, installation of third-party parts, etc.) may
result in hazards for patients and users. In the event of uncoordinated modifications to the table, the
Declaration of Conformity loses its validity and the warranty shall become null and void.
We cannot be held liable for damages resulting from uncoordinated modifications.
Only original Dewert spare parts may be used.
