All positions of the switch levers are maked "red" or "yellow" . All levers have to point on one colour,
depending on the direction of use. If the rope during the lifting Operation does not grip in the pulley
immediately, draw once jerky at the unloaded rope side.
4.4 Rescue of a helpless person that is hanging by its lanyard
Caution: Wear work gloves!
Securely fix the rescue device for descending and lifting to a suitable anchor point according to EN
795 using the karabiner that is attached to the device.
Fix the karabiner hook of the short rope end to the rear eye of the full body harness of the casualty
and secure it. The switch lever of the holding ratchet must point towards the direction of the short
rope end that is fixed to the rear eye. By turning the handwheel, lift the person to be rescued so far
that it can be released from the connecting means. If it is lifted by the Ratchet, turn the change lever
of the Ratchet toward to the loose end of rope. Using the lifting ratchets, lift the casualty until the
person can be disengaged from the lanyard.
To lower the person, all ratchet levers must be switched. Again all switch levers have to be
switched onto one colour; all on "red" or on "yellow".
Caution: The ratchets cannot and must not be switched over when under load.
Option 1: Lift with the Handwheel
To switch must be carried out as follows. By turning the Handwheel the load lifting and holding.
Thereby, the holding ratchet is released and can be switched.
Keep the load continues with the handwheel. Now insert the unloaded rope in the open eyebolt,
tighten down and hold tight.. To begin the descent release the handwheel slowly and let the rope
slide slowly through the hand.
Option 2: Lift with the Ratchet
In order to shift the switch, first the holding ratchet and then the lifting ratchet must be unloaded by
executing the following steps:
Using the lifting ratchet, lift the load and hold it. This unloads the holding ratchet and its switch lever
can be turned.
Caution: Continue to hold the load with the lifting ratchet.
Now put the unloaded rope in the open hook, firmly pull downwards and hold tight. You can now
slowly unload the lifting ratchet and operate switch lever.
Otherwise the lifting ratchet has to be removed from the device by actuating the eject button.
During this process the load has to be held with the rope. That means that the load is transferred
from the lifting ratchet to the rope that needs to be tautly held down. To start the descent, let the
rope slowly glide through your fingers and then let go. The descent velocity will be automatically
controlled by a centrifugal brake. When rescuing a casualty from a ladder the descending process
often needs to be manually controlled as well. That means that the rescuer has to let the rope that
is running upwards glide through his fingers in order to exactly control descent velocity and slowly
guide the casualty over possible obstacles.
During the rescue operation take care for direct or indirect visual contact or another suitable means
of communication to the casualty.
4.5 Rescuer accesses the casualty in order to recover her or him
The MRG9 easy+ descender and rescue lifting device also enables the rescuer to access the
casualty directly with the device. After reaching the casualty, the rescuer then hooks the casualty in
and, if necessary, lifts him- or herself and the casualty in order to release the casualty's lanyard and
they then descend together.
This rescue operation may only be executed by persons who are specifically trained in the safe use
of this application and have the necessary knowledge.
The rescuer shall remove the whole equipment set from field service for inspection, repair or
replacement if it has been subjected to a rescue operation.
5. Maintenance, storage, transport and repair
If necessary, clean descender device and descent rope after use. Clean with fine-fabric detergent
and plenty of water (40° C).
Dry the device if it has become wet during use or during cleaning.
