using an appropriate, independent second backup line/belay and in compliance with the safety instructions.
27.
Rescue exercises can be designed to be very versatile and very complex and therefore do not meet the specified standard
test procedure. This can lead to premature wear of the descender and rope. The reason for this can be for example: Lower
descent heights - the rope runs through the device more often; reciprocal strain from the lifting device and descent - gear
box, pulley and rope are strained more heavily; mainly unilateral strain on the device - gear box, pulley and rope are very
heavily used; turning the hand wheel against the backstop - excessive force may result in backstop failure and block any
descent; in addition, the effects can be exacerbated, for example from how the user handles the rope/device and the
ambient conditions (environmental influences, pollution, chemical effects, edge loads, etc.)
28.
The following recommendations on use should be observed: The descent rescue equipment and the descent ropes can be
strained until they reach their tested descent load (7,500,000 joules). Any descent load by the devices shall be documented
in the test log after the end of the exercise. When the maximal required descent work is reached, the device with the
corresponding notation in the test log shouldt always be sent to the manufacturer. If the device is mainly strained on one
side, then the maximum possible descent load (3,750,000 joules) is halved.
29.
The exercises should be planned so that the maximum possible descent load of the device to be performed (7,500,000
joules) or (3,750,000 joules as per Item 28) is never exceeded.
30.
The descent rescue device heats up from the centrifugal brake. If several exercises take place consecutively, plan an
ppropriate time to cool down the device between exercises. Always wear gloves to prevent burns and injuries.
31.
After the end of the exercises - no later than one day after an exercise - have the descent rescue device checked by a
qualified person (

Device storage and transport
The packaged device, rope and accessories are to be protected from any external influences. These include
extreme heat or cold, electric influences, strong sunlight (ultra-violet degradation), sparks, knocks, falls, sharp or
pointed objects, damp or other mechanical or aggressive chemical effects. The device shouldt always be transported in suitable
packaging or one specified by the manufacturer.
Long-term packaging
Different requirements for long-term packaging demand a careful selection of the appropriate storage/transport container. Although
the long-term packaging in equipment bags is protected by padding, it is not possible to exclude mechanical damage to the long-
term packaging during recurring transport, e.g. due to knocks, being thrown about, hitting corners, etc. Sturdy transport cases are
recommended for long-term storage and mobile storage locations (e.g. motor vehicles) or recurring transport to places of use.
Cleaning
Clean the device after use if necessary. Rub down the rope with mild, luke-warm soapy water, rinse clean and dry.
Drying shouldt be by natural means, i.e. do not hang up directly over heat sources. Store the descent device in a dry, well-ventilated
and dark location. Avoid contact with acids, corrosive substances and oils.
Before using disinfectants, you have to contact the manufacturer due to the complex legal product classifications based on the
specific applications and constituents.
Accessories
Please note: In order to prevent a negative impact on the safe function of the controlled descent device, it is only permitted to use
accessories approved by the manufacturer (e.g. rescue clamps to DIN 19428:2018, protective covers, etc.). The manufacturer is
not liable for any accidents involving the life and limb of the user if using non-approved accessories.
). Only defect-free devices can be reused.
