One karabiner hook is attached to both ends of the descent rope. The descent rope runs through a
rope pulley. If one rope end with karabiner hook is at the upper descent point the other rope end
with karabiner hook must be at the lower descent point.
Caution: Remove the lifting ratchet from the device (only MRG9 easy+). It is not needed for
a descent alone.
The first person has to put on the rescue harness that is attached to the descent rope (see pictures
4 and 5).
Please follow the instructions of use for the rescue harness or the fall arrest harness.
Now pull at the long descent rope hanging down until a taut connection between the descender
device and the rescue harness has been established (see picture 6).
For this purpose you have to shift the switch lever of the holding ratchet towards the short descent
rope.
Caution: Never let yourself fall when the rope is slack.

Now shift the direction switch of the holding ratchet towards the long descent rope. Turn your face
to the wall and start the descent (see pictures 7 and 8). The descent velocity is automatically
controlled. Look out for obstacles! When you reach the ground, take the rescue harness but leave it
on the rope (see picture 9). If several persons need to descend, at least 2 rescue harnesses are
required. Now the second person has to fix the karabiner hook that is attached to the rope end that
is now located at the higher point of descent to the attachment point of the second rescue harness
and secure it. Now put on the rescue harness of the descent rope (see picture 4 and 5).
Caution:
Please follow the instructions of use of the rescue harness or the fall arrest
harness.
Pull at the long descent rope hanging down until a taut connection between the descender device
and the rescue harness has been established (see picture 6). Now shift the switch lever of the
holding ratchet towards the long descent rope. Turn your face to the wall and start the descent (see
pictures 7 and 8). When you reach the ground, take off the rescue harness but leave it on the rope
(see picture 9). The other end of the descent rope with the rescue harness attached is now again at
the upper descent point and the third person can pull the harness towards himself. This person has
to leave it attached to the karabiner hook of the descent rope and put it on. (see pictures 4 and 5).
Now pull at the long descent rope until a taut connection between the descender device and the
rescue harness is established (see picture 6). Now shift the switch lever of the holding ratchet
towards the long descent rope. Turn your face to the wall and start the descent (see pictures 7 and
8). When you reach the ground, take off the rescue harness but leave it on the rope (see picture 9).
Any other persons can descend in the same way as person 3 one after another.
4.2 Simultaneous descent of casualty and rescuer
The rescuing person can descend at the same time as the person that is rescued. For this operation
both persons have to attach the karabiner hooks of the upper descent rope end to the respective
attachment points of the rescue harness and secure them.
For this use the rope should not be pulled through the open hook.
Caution:
Make sure you are appropriately secured against falling from a height until the
beginning of the descent (on person after another or two persons
simultaneously). Do not descend above liquids or loose bulk goods.
4.3 Lifting function
To lift a person from a lower to a higher place the rescue device for descending and lifting needs to
be securely fixed to an anchor point according to EN 795 using the karabiner hook that is attached
to the device. Remove lifting ratchet. Lower the rescue harness located at the shorter descent rope
end using the descent rope. For this purpose the rope has to be pulled through the device. The
switch lever of the holding ratchet needs to point towards the direction of the long incoming rope.
The person that needs to be lifted has to put on the rescue harness that is attached to the descent
rope. The lifting operation can be done either with the handwheel or the Ratchet. For the lifting, turn
the switch lever of the holding ratchet to point towards the direction of the load-bearing rope. By
turning the handwheel, the helper can begin the pulling out. For the lifting with the Ratchet plug this
into the adapter. The switch lever of the lifting ratchets also needs to point towards the direction of
the loose (unloaded) rope end. Start lifting.
