Device safety
Greiner chairs were built in accordance with the applicable national and international standards and regulations according to the current state of the art. This chair meets the requirements for safety and functionality. It bears the CE mark, which documents compliance with the basic requirements for medical devices. The chair described in this instruction has been designed, manufactured and meets the requirements of the Medical Device Regulation (EU) 2017/745 (MDR) of the European Parliament and the Council. According to the classification rules in Annex VIII of the MDR, the chair is an active medical device of risk class I (electrical versions only). The validity of the declaration of conformity expires if changes are made to the chair by the customer or third parties, e.g. modifications of any kind, use of external accessories, changes to the software, removal of warning and information signs (no claim to completeness). Due to the chosen robust, interference-proof design of the electrical adjustment devices, the chair is largely tolerant to EMC interference from other electrical equipment operated in the vicinity. Despite comprehensive EMC testing, it is possible that other devices may be disturbed by the chair. In such cases, either switch off the chair completely by disconnecting the mains plug or disconnect it from the mains, or, if necessary, keep a larger distance from the disturbed device and change the orientation to each other. If possible, do not use the same outlet. This applies in particular to the simultaneous use of highly sensitive measuring instruments. Their measurement results may be influenced under certain circumstances. The chair can be equipped with accessories on delivery (see 5 Accessories). If necessary, observe the instruction manuals for the accessories. For further information, please contact your authorised specialist distributor. All prohibition, warning and message symbols or instructions on the chair must be observed. The symbols and notes must always be legible and complete. Damaged or lost symbols or notes must be replaced true to the original. The chair is mainly made of steel tubes or steel profiles. The surfaces are either powder-coated or coated with zinc or chrome. All surfaces are harmless against skin contact.

3.3
Scope of delivery
Configuration options There are basically 2 different versions of the MEDSEAT chairs. They differ in the way of the height adjustment. The height adjustment is either operated hydraulically or electrically. TIP
A version with hydraulic height adjustment can never be combined with an electric backrest adjustment and electric synchronous adjustment of backrest and legrest or even a separate electric adjustment of backrest and legrest. The upper part is always adjusted manually by means of a lockable gas spring. Depending on the model, the leg rest may be adjusted synchronously with the backrest. The version with hydraulically height adjustment cannot be combined with a mobile base part.
The versions with electrically height adjustment differentiate between manual and electrically backrest adjustment. Depending on the version, the legrest may be adjusted synchronously with the backrest. An additional electric drive allows separate adjustment of the legrest if necessary. All electrically driven upper parts can be combined with hands controls in the backrest. Furthermore, all versions with electrically height adjustment can be combined with a mobile base part. Every MEDSEAT chair can be equipped with a pivoting seat surface. This opens up a wide range of configuration options for a MEDSEAT chair. The chair can be equipped with accessories (see 5 Accessories). Base part

3.5
Requirements on the place of operation
For the operation of the chair, an appropriate mains supply and, if applicable, an equipotential bonding connection is required at the place of use. If this is available and the building's wiring permits it, the chair must always be connected to the equipotential bonding system (see 4.7 Equipotential bonding pin).
3.6
Check before commissioning and reassignment
After the commissioning work has been completed, and before any occupation by a new patient, the chair must be cleaned and disinfected (see 6 Cleaning and disinfection).
CAUTION Risk of infection from contaminated chair. The chair must be cleaned and then disinfected before the first use. This also applies before each use (occupation by a new patient). A functional check of the chair must be carried out immediately after cleaning and disinfection and before use.
WARNING Risk of injury for patient, user and third parties. The chair must be checked for functional safety after first commissioning and every occupation by a new patient. It must be ensured that the chair can be used as intended without endangering the patient, the user or third parties. If the chair is put into operation for the first time or before any occupation by a new patient, the same functional check must be carried out as for recommissioning after storage (see 8.3 Check before recommissioning). General check of the overall condition of the chair for soiling, condition and damage, completeness and legibility of stickers, symbols and instructions, clean if necessary in accordance with the manufacturer's specifications or those of the operator and repair if necessary. Visually inspect the mains cable and plug, foot switch, as well as all other electrical cables and connectors for breakage, proper installation (e.g. strain relief), clamping or friction points etc. and repair if necessary (if available). Functional check of the electrical adjustment devices and the control system. All electric actuators must be operated once up to their end positions. Pay particular attention to changed operating behaviour, unusual noises, speed, smooth running, odours and increased temperature and repair if necessary (if available). Carry out a functional check according to the installed turning lock (locking, freewheel) and repair if necessary. Carry out a functional check according to the used headrest and repair if necessary. Carry out a functional check of the rolling device of the mobile base part and repair if necessary (if available). Carry out a functional check of the manual backrest and synchronous adjustment by means of a gas spring and repair if necessary (if available). Carry out a functional check of the hydraulic height adjustment and repair if necessary (if available). Any defects or damage found must be remedied immediately. The chair must not be used before the defects or damage have been remedied. The chair must not be operated in a defective or faulty condition in which the chair could endanger patients, users or third parties. A defective or faulty chair must be clearly marked "DEFECT". The marking must be done in such a way that the defective condition is clearly identifiable for everyone. Inform the operator for intensive inspection during repair.

Operation
The chapter operation describes the functions of the chair and its performance features. Prerequisites for operation The chair may only be operated and used in accordance with its intended use, the generally recognised rules of technology and the national occupational safety and accident prevention regulations valid at the place of use (see 2.4 Intended use). In Germany, the provisions of the Medical Devices Act (MPG), the Medical Devices Operator Ordinance (MPBetreibV) and the relevant statutory regulations must be observed. To ensure safe operation, the following points must be strictly observed. Before using the chair, the user must familiarise him- or herself with the contents of this manual and observe the safety instructions for the individual points of danger. The chair must be cleaned first and then disinfected (see 6 Cleaning and disinfection) before commissioning and before any further use (occupation by a new patient). A functional check must then be carried out afterwards (see 3.6 Check before commissioning and reassignment). The chair does not have an EMERGENCY STOP command device. Access to the mains plug must therefore be guaranteed at all times in order to allow the deactivation of the chair in an emergency situation by disconnecting the mains plug. Avoid mechanical stress on the mains cable or plug. Do not crush or trap the mains cable anywhere. Carry out an immediate visual check after each mechanical load on the mains cable or plug. Tighten all handwheels, clamping levers and clamping screws etc., including those on accessories, before use. Due to the widely differing stresses, operating conditions and frequencies at the place of use, the setting by the manufacturer of a central specification for the frequency of safety inspections does not make sense. In accordance with the Medical Device Operator Ordinance (MPBetreibV), the operator must specify the test period for the safety inspection on the basis of a risk assessment (see 2.2.1 Safety inspection).

When adjusting the chair, ensure that there are no limbs of the patient, user or other persons, especially children playing between the lower and upper sections, as well as between the back or armrest(s) or the leg section and the floor, which could be trapped and injured. Pets should generally be kept away from the chair and no other objects should be stored under the chair. Ensure that the chair does not get caught on walls or furniture.
DANGER
Risk of injury due to unintentional movements of the chair. The chair is not intended for unsupervised use by children or handicapped persons. In such situations, always ensure that the operating lock is activated as long as there is no trained user on site. (see 4.5 Activating / deactivating the operating lock)
The chair may only be occupied by one person at a time. The maximum patient weight must not be exceeded and must be evenly distributed on the seating surface. Do not sit or rest on the backrest upholstery, the legrest upholstery, the arm support or the foot support.
CAUTION Risk of falling or injury if seating position is set too high.
GREINER_medseat_manual_EN_4615502_rev_9.docx
In order to avoid or reduce injuries caused by falling, we recommend (except when carrying out care measures on the patient) moving the chair to the lowest position. This generally applies when manoeuvring the chair (see 4.15 Manoeuvring) and in particular when sitting down and standing up of the patients (see 4.16 Sitting down and standing up of the patients). When operating other devices on or near the chair, that are equipped with cables, air hoses or similar, make sure that these lines cannot get trapped in the moving parts of the chair or be damaged in any other way.
WARNING Risk of injury due to the use of unsuitable accessories. Only original accessories from GREINER GmbH may be used. The attachment of accessories from other manufacturers (e.g. fixing belts etc.) lies within the responsibility and duty of care of the operator.

Basic position
If patients want to sit down on or get up from the chair, as well as before manoeuvring, the chair must be brought into the basic position. Move the seat height all the way down (see 4.9 Height adjustment). Raise the backrest completely (see 4.10 Backrest and synchronous adjustment). Swivel the arm supports downwards (see 4.8 Armrests). Lock the upper part (see 4.11 Fixing the upper part). If necessary, swivel the leg section all the way down (see 4.10 Backrest and synchronous adjustment). If necessary, fold in the foot support completely (see 4.14 Foot support (foldable)). If necessary, move the rotatable seat surface to the middle position (see 4.13 Rotatable seat surface). If necessary, retract the rolling device on the mobile base part (see 4.15 Manoeuvring).

Operation
4.5
Activating / deactivating the operating lock
The activation or deactivation of the operating lock (electrical versions only) is described here. For the activation or deactivation of the operating lock up to the delivery date in September 2015 (Software Ver. 1.0 and 1.1) (see service manual). Activating the operating lock prevents the chair from moving accidentally or unintentionally. TIP
After disconnecting the mains plug and then plugging it back in, the chair remains in its previous operating status. This means, for example, that the operating lock was activated before disconnecting the mains supply, so the operating lock remains activated even after the mains supply has been restored. The control unit remembers the current operating status.
Activating the operating lock 1. To activate the operating lock, press and hold the two buttons of the foot switch (1) to adjust the seat height (up (2) - down (3)) or the two buttons of the hand control (4) to adjust the seat height (up (5) - down (6)) simultaneously for approx. 5 seconds. 2. A short beep signals the activation of the operating lock. Deactivating the operating lock 1. To deactivate the operating lock, press and hold the two buttons of the foot switch (1) to adjust the seat height (up (2) - down (3)) or the two buttons of the hand control (4) to adjust the seat height (up (5) - down (6)) simultaneously for approx. 5 seconds. 2. A short beep signals the deactivation of the operating lock. 1 3
