of communication to the rescued person (eg direct or indirect visual or radio contact). If the fall protection system is
also connected to the same anchorage point the requirement of the anchorage point shouldt be increased according
to the technical rules. In the scope of the ANSI/ASSE standards, for fall protection, the requirements to the anchorage
point for the fall protection equipment according to ANSI/ASSE Z359.1 (22,2 kN) are to be complied with and shouldt
be independent from the anchorage point of the technical rescue equipment.

The ABS 4 W / WH / WHPL / WHSL is an automatically acting descent rescue device. During the descenting process
heat is produced by friction. Components of the devices which needs to be touched during the descenting process
do not heat up over 48°C. other components are significantly warmer

A controlled descenting process is essential, as in loss of control it can be very difficult to regaining

Do not descent above hazardous material, obstacles, live constructions or mobile machine components without
observing the required safety distances ,
20.
The descent rope is connected to the safety harness of the injured person by using an appropriate connecting
„Slack rope" between person and the anchorage point shouldt be avoided. Full body according to EN 361/ ANSI/
ASSE Z359.1 or rescue harnesses according to EN 1497 ANSI/ASSE Z359.4 are permitted for use of the descenting
device. The user instruction of the safety harness shouldt be observed.
21.
Weather influences, e.g. strong wind and technical conditions, as well as the weight of the free-hanging in running
rope can affect the descenting process negatively.
Application
For the ABS 4 WH / WHPL / WHSL: Perform a function check as described in item 4

connect the rescue device to the attachment point. The carabiner of the outgoing rope is connected to the ring or fall
arrest D-ring of the victim's harness. Use the lift function to lift the victim until the fall arrest is released. To do this, use
the switching bolt to turn the backstop on in the „Lift" direction. The victim is subsequently lifted until the fall arrest is
released by turning the hand wheel in the lift direction. The injured person is subsequently lifted by actuating the lift
control device (hand wheel/ratchet lever) in the lifting direction until the fall arrest is released.
The nominal lifting capacity is 140 kg / 200 kg, ANSI 282 kg,minimum capacity is 50 kg, the maximum lifting height is
200 m. Release the fall arrest of the victim and begin descenting as follows: Turn the hand wheel in the „Lift" direction
until the backstop is released. Hold the hand wheel. Press the switching bolt into the „free running" position. Hold the
lift control device firmly. Press the switching bolt into the „free wheeling" position. Now transfer the force to the rope
and relieve the lift control device. Now start descenting slowly. The device can be slowed down either by holding the
hand wheel or by holding on to the upward running rope . Additional holding force can be achieved when descenting
by redirecting the upward running rope via the hooks and fairlead of the roping rescue device. The descenting length
should be free of obstacles. The rope should prope rly run in the descender.
Evacuation of a single person using the ABS 4 W: Perform a function check as described in item 4. The user

slings the connector of the outgoing rope as vertically as possible over his head to a suitable anchorage point. The
descender's carabiner is connected to the D-ring (see the harness instructions) (
bag down (be careful not to endanger anyone) or carry it on your harness. Place the incoming rope over the pulley
and hold. Make sure that all carabiners are locked. The user gets into the descenting position. Now unhook the fall
arrest and slowly starting descenting (open hand until the rope starts to slip. Attention: There is a risk of burns, wear
suitable protective gloves!). Make sure that the rope runs properly out of the bag and into the device. Open your hand
completely and the machine brakes automatically. The descenting speed is 1.5 m/s.
24.
Evacuation of several persons using the ABS 4 W: Perform a function check as described in item 4. Sling the
device as vertically as possible over the user. Connect the carabiner of the outgoing rope to the ring or D-ring of
the harness (see the harness instructions). Pull the rope taut, throw the rope bag down (be careful not to endanger
anyone) or set it safely aside. Make sure that the rope runs properly into the device. Once the first person has
reached the ground, unhook the descent rope from the harnesses D-ring. The opposing rope now becomes the
descenting/descent rope and the procedure is repeated. The device does not have to be switched.
25.
Rescue by carrying the device: Sometimes it may be necessary for a rescuer to rappel to an injured person
(

)
. In this case, the rescuer hooks the ABS 4 W&WH-type descent rescue device onto the chest eyelet of

his EN 361 and EN 813, ANSI/ASSE Z359.1 fall arrest harness. The carabiner of the outgoing rope is connected
to the respective anchorage point. The rope bag is thrown down (be careful not to endanger anyone) or carried on
the harness. The rescuer now gets himself into the descenting position. Once more, checks carefully whether safe
descenting is possible. Then he releases his fall protection and then rappels to the victim. By actuating the lift control
device, the rescuer can lift himself/herself together with the injured person in the lifting direction, and the catching
system of the injured person is released. Always make sure that the incoming rope runs properly into the descender.
Descenting can be slowed down either by holding the hand wheel or by holding on to the upward running rope. Once
the victim has been reached, the rescuer stops descenting and positions himself by inserting the backstop or ensures
he has a secure stand near the victim. If necessary, an additional fall arrest is required (redundant system) for the
rescuer. Attention: The victim may not be hooked into the rescue system and taken over.

To perform a safe rescue in case of an emergency rescue it is essential that the users receive professional training
by specially trained instructors. These exercises shouldt be performed under similar working and operating conditions
