1.10 Meaning of the serial number
The serial no. is located on the type plate or is shown separately next to the type plate of the table. This
number is unique and firmly linked to this specific individual product. It enables us to identify this table model
and trace back assemblies/safety-relevant components at any time.
Please always state this serial number when enquiring about spare parts.
2. Operating manual
2.1 Table design
When designing the table frames, special emphasis was placed on functional and operational safety. The
number of possible pinching points has thus been minimised, while remaining ones have been covered or
protected with spacers to prevent injury, thus ensuring safe and yet simple operation. Nevertheless,
necessary caution must always be exercised when using the table.
The table consists of the following assemblies: underframe, telescopic column, upper frame and upholstery.
Depending on the respective version, these assemblies can feature further attachment parts. The surfaces of
the welded design are plastic coated. The lifting motor for the height adjustment is located inside the covered
telescopic column. The electrical adjustment system does not pose a hazard to the health and safety of the
user or the patient when used as intended. The lifting motor is activated by a low control voltage.
2.2 Height adjustment
Height adjustment
To adjust the height, the enclosed foot switch (optionally also hand switch) is operated according to the
marking. Beforehand, brief activation (double tap) must take place via the foot switch (or the hand switch).
Please refer to section 7. The table is lifted or lowered.
Height adjustment using foot switch rails (optional)
The electric motor for height adjustment is operated by a switch rail attached to the long side of the table,
which can be operated with your foot. Press the switch rail down = the table is lifted. Lift the switch rail up =
the table is lowered. Here, too, brief activation (double tap) must take place beforehand (see section 7). The
arrangement of the switch rails results in a changed lying surface height.

Dewert User Manual 6000E and 6800E –Updated 03.2023/4 MDR Page 6 of 13
Note on operation
The electric motor is to be operated in intermittent duty mode. This means that a maximum duty cycle
of 25 s must not be exceeded. Before switching the motor back on, an interruption time of at least 400
s must be observed. If the maximum duty cycle is exceeded, an internal thermal switch (protective
temperature limiter) in the motor interrupts the power supply to the actuator. After the electric motor
has cooled down, the thermal switch automatically reconnects the power supply to the actuator.
2.3 Head part adjustment
Despite the very robust and strong design of the gas spring, the head part must not be used for
sitting!
Head part adjustment upwards and downwards (positive and negative direction) using a gas spring
The head part is adjusted using a gas spring. To operate, press the release lever, which is located at the end
of the head part underneath the upholstery part, in the direction of the upholstered surface. The head part is
lifted slowly to the positive end position. To lower, press down the head part and operate the release lever at
the same time. Once the desired position has been reached, let go of the release lever.
2.4 Adjustment of other sections
Despite their robust and strong design, the adjustable sections must not be used for climbing onto or
sitting on the table. The area provided for this purpose is located directly above the telescopic
column.
Lying surface adjustment to the inclined position using an electric motor
(models 6050E, 6051E, 6810E, 6075E, 6875E, 6085E, 6885E)
The foot part is adjusted using a separate electric motor. By operating the hand switch, the inclination of the
lying surface can be varied steplessly. Please also observe the necessary double-tap function (see section 7).
With the head part in downwards adjustment (negative position), at maximum inclination and when lowering
the table at the same time to the lowest position, attention must be paid to the head part.
Should the head part come into contact with the floor, the gas spring is automatically triggered and the head
part is lifted in upwards adjustment (positive direction). This is for emergency use only and is associated with
noise.
Always observe: There must be no persons in the adjustment range of the entire lying surface.
Upholstery segment adjustment using a gas spring
The upholstery segments are adjusted using one or more gas springs. To operate, press the release lever in
the direction of the upholstered surface. The upholstery part is lifted slowly to the positive end position. To
lower, press down the upholstered segment and operate the release lever at the same time. Once the desired
position has been reached, let go of the release lever. The strength of the gas spring ensures relative ease of
adjustment despite the patient’s weight. Consequently, when unloaded, more force is required to adjust the
respective upholstery part horizontally again.
2.5 Movability (optional equipment)
Individually lockable castors
The castors can be locked using the foot-operated brake on the castor housings. In this case, the castors can
neither be moved nor rotated. To release, operate the brake on each castor again.
Please note: Standard castors are not electrically conductive = optional equipment. You can recognise
conductive castors via the respective marking = yellow dot on the side of the running surface or a yellow ring.
With this movability option, access to the patient is improved during examination and treatment thanks to easy
positioning within the room. Transporting patients is not considered as intended use.
Central movability
By operating a lever (on the outside of the table feet), all four castors are activated simultaneously. The
following moving options exist:

Dewert User Manual 6000E and 6800E –Updated 03.2023/4 MDR Page 7 of 13
Stage 1: The castors of the table are locked and can neither be moved nor rotated.
Stage 2: = centre position: The castors are released and can be moved and rotated, the table can be moved
in all directions.
Stage 3: Three castors are released (= can be moved and rotated). The fourth castor is locked and cannot be
rotated (directionally locked castor), i.e. the wheel rolls in a fixed position and helps to steer the table in the
intended direction.
Please note: Rotational movement is only prevented when the castor is swivelled parallel to the lying surface.
This then allows the table to be moved in a straight line without pulling off to the side.
Wheel-lifting/fixing mechanism
The wheel-lifting/fixing mechanism allows a combination between fixed and movable table. There are two twin
castors on each short side of the underframe and foot levers at each corner. The foot levers consist of two
ergonomically arranged counter holders. This way, the table can be lifted and lowered quietly with your foot.
The wheel-lifting/fixing mechanism is not controlled centrally; a foot lever must be operated on each short side
of the table in order to lower the table onto its feet or to place it on the castors. This option ensures the device
can be simply relocated; however, the device is not intended for transporting patients (ground clearance
(distance foot - ground) when moving the table is approx. 14 mm).
2.6 Additional equipment
Nose opening
If a nose opening is upholstered in the head part as an optional equipment feature, the opening can be closed
with a cushion (optional). To open up the nose opening, reach under the head part when the table is standing
still and press the cushion out from the bottom upwards (a slight amount of pressure is required).
To close it, simply insert the cushion into the opening (a slight amount of pressure is required).
3-sectioned head part (model dependent optional equipment)
The 3-sectioned head part consists of an adjustable head part as described under 2.3 and additional
armrests, which can be lowered and removed steplessly, to the right and left of the head part. The clamping is
released by loosening the knurled screw located underneath each armrest. The armrest can now be pulled
down through a range of approx. 180 mm. Re-clamping takes place by subsequently tightening the knurled
screw. To remove the armrests, loosen the knurled screw located directly underneath the head part. The
complete armrest can then be pulled off the head part from the side. The armrests must not be used for
sitting. They only serve to support the patient’s arms.
Paper roll holder (optional equipment)
The paper roll holder consists of a holding bar and angle mount brackets or retaining brackets.
In addition to the stainless steel bar, the paper roll holding bar consists of a spring-loaded stainless steel sleeve
featuring a round steel gripping disc at the end. To insert the holding bar, feed the guide cotter pin of the stainless
steel bar into the rear hole of the angle mount bracket/retaining bracket. Then push the sleeve with the gripping
disc against the spring force and feed the front guide cotter pin into the second hole. Then relieve the spring
tension on the sleeve. To release the paper roll holder, proceed in the same way.
Laterally lowerable side guard (optional)
Operating the side guard:
Hold the centre of the rail of the side guard with one hand and release it by moving it minimally sideways
(either towards the head or foot part). At the same time, use your other hand to pull out and turn the locking
pin (red knob) located in the centre of the side guard underneath the upholstery frame. Press down or pull up
the side guard using the rail until the locking pin engages. After the locking pin has engaged, the side guard is
secured in place. To check whether the side guard has engaged properly, move it sideways on the rail (either
towards the head or foot part). Only limited movement should then be noticeable.
Always operate the side guard with the necessary caution. Never operate the side guard if the hands,
fingers, etc. of another person are located between the bars or on the mechanism of the side guard.
Risk of being crushed/pinched!!!
The laterally lowerable side guard is completely screwed in place. If the side guard becomes too loose or has
excessive lateral play over time due to use, it can be readjusted by tightening the screws. The moving parts of
the side guard should be re-lubricated slightly at regular intervals (spray oil, e.g. Ballistol).

Dewert User Manual 6000E and 6800E –Updated 03.2023/4 MDR Page 8 of 13
Side guard, lowerable, for side rail (model dependent optional equipment)
This side guard can be placed and fixed on any side rail using a clamp. By loosening the toggle screw of the
clamp, the position and height of the inserted side guard can be shifted and adjusted respectively. Complete
lowering below the upholstery level can only be achieved if the guide points in the direction of the upholstery
when the side guard is inserted into the clamp.
Please note: Never use the side guard as a push handle. It has not been designed for this purpose.
2.7 Special features of model 6100E
The telescopic column of the table is attached directly underneath the foot end of the table.
The upholstery support is a thick tubular steel frame which enables use without crossbars. This creates a free
area between the end of the frame (end of lying part/beginning of head part) and the telescopic column.
Here, a C-arm examination can be performed vertically in the chest to pelvis area of the lying patient.
Optionally, the table can be equipped with an HPL support plate and removable upholstery. The upholstery is
attached to the frame using hook-and-loop tape on the sides. To do this, affix the tape on the underside of the
frame. The upholstery can be removed fully.

Technical data subject to change
* Weight load not for individual upholstery sections, but only centrally on the fixed lying surface above the
telescopic column
The motor is equipped with a thermal protective switch as standard. This causes the motor to cut out if the weight
load is too extreme or the motor’s duty cycle (DC: 25 s/400 s) is exceeded. The table should be ready for use
again after a 15-minute rest period. There is, therefore, no risk of overloading the motor.
The mechanics of the tables have been designed with extensive safety margins in mind. The max. patient weight
is provided with a 4-fold static safety factor, i.e. the design has been fully tested for a 4-fold load.

5. Cleaning instructions
Upholstery covering
There are two different collections of upholstery covering to choose from:
•Skai Pandoria Plus (manufactured by Hornschuch/Continental in Germany)
•Skai Toronto EN (manufactured by Hornschuch/Continental in Germany)
For cleaning and disinfection, a selection of agents from various manufacturers has been tested for
compatibility. Please refer to the separate enclosed sheet.
Not oil-resistant, not antistatic!
A different upholstery covering is necessary for these requirements.
The table is equipped as standard with the Dewert hygiene standards, which enable optimal cleaning and
disinfection:
•Hinge lids are made of the identical upholstery covering
•All undersides of the upholstery parts are coated with an upholstery covering and can thus be cleaned
and disinfected
•Vent holes underneath the upholstery:
For the homogeneous foam to recover quickly, a rapid exchange of air is necessary. To ensure this, there
are individual vent points on the underside of the upholstery, which are hygienically sealed with special air
compensation caps that assume a valve function.
•Easy hygiene due to an open design
•Optional: Upholstery covering Skai Toronto EN with staynu
Table frame
The plastic-coated table frame can be cleaned with mild household cleaners, if necessary. Do not use
aggressive, abrasive or corrosive agents. Heavily soiled chrome-plated parts can be cleaned with a chrome
polish (e.g. Sidol). After cleaning, dry the frame with a soft dry cloth. Seal deep scratches and worn areas with
suitable repair agents to prevent moisture penetration.
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, set all the adjustable sections to the horizontal position.
Disconnect the power plug from the mains socket beforehand.
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 50,000 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, with frequent use even after 1 year. The maintenance procedures
can be carried out by qualified personnel/instructed personnel.
The scope of maintenance includes, for example:

Dewert User Manual 6000E and 6800E –Updated 03.2023/4 MDR Page 11 of 13
•Thorough visual inspection of all components, especially motor and switch with mains supply line
•Function check
•Check all swivel joints for completeness.
•Check proper fit of the screw connections, especially the screw connection of the optional roller system.
•Lubricate the swivel joints and operating levers slightly with low viscosity spray oil, 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.
All drive components must not be opened! Risk of electrocution!
Work on the electrical system may only be carried out by qualified and authorised personnel in
compliance with all relevant provisions and safety regulations!
Foot and hand switches for adjusting the electric motor as well as gas springs are wearing parts whose
function may be impaired over the years depending on the frequency of use.
Both can be replaced without too much effort. Please request the corresponding installation diagram, if
required. Replacement parts can be obtained directly from Dewert.
7. Safety devices
Tables with electromotive adjustment must have an automatic device to deactivate the control elements when
moving the table. Reactivation of the control elements must be designed in such a way that they cannot be
triggered accidentally by patients, users or third parties.
The actuator of this table is equipped with an integrated safety device to protect against
unauthorised/unintentional operation. This device goes into “sleep mode” 3 seconds after the last operation
and can only be reactivated with a defined switching sequence, the so-called double tap.
To “wake up” the actuator or the control unit, first press the desired direction of travel for approx. 1 second on
the control element. After a short waiting time (1-2 seconds), press the desired direction of travel again and
the actuator can be moved for a maximum of 30 seconds in this direction of travel.
If the switching cycle of the double-tap function is not observed, the actuator cannot be operated. After 30
seconds of operation in one direction of travel, the actuator switches off and goes into sleep mode. The
actuator can still be operated for up to 3 seconds after the last operation to ensure fine adjustment. Within this
time window, it is possible to move in each direction of travel again for a maximum of 30 seconds. The
actuator always goes into “sleep mode” automatically 3 seconds after the last operation.
