between the attachment point and the jamming cleat. Care should
be taken that the working (load carrying) end of the rope exits the
device by the jamming cleat and the free end of the rope by the
carabiner.Then thread the bight around the jamming cleat, between
the upper parts of both flanges and finally catch the jamming cleat
with the bight. Eventually move the jamming cleat back in the
descender so that it engages the rope. If the rope has not been
inserted correctly the descender will not be able to perform its
function and will hence be of no use.
Figure 3: OPERATIONAL CHECK
Before each use carry out an operational check of the device by
testloading it with your body weight while secured by other means.
Additionally it is essential to assess the reliability and security of the
entire safety system you are relying on: adequate resistance of the
anchors (EN 795) and their correct (higher) positioning to arrest a
fall and prevent pendulum effects, correct positioning of the ropes
– e.g. protecting sharp edges or points of rubbing, preventing ill
running of the descender, redundancy, etc.
– and to tie a stopper knot at the free end of the rope. Any overload
or dynamic loading of the descender may damage the rope.
Figure 4: DESCENT
While loading the system, the user should hold with one hand the
free end of the rope (approx. 0.5 m below the descender) and with
the other hand gradually push the handle against the descender's
body (fig.4/A). This unblocks the rope and allows for a controlled
descent. The maximal permitted speed of descent is 2 m/s. By
increasing pressure on the handle the user will activate the
descender's second braking position (anti panic) and when the
pressure is high enough the descent will be stopped entirely
(fig.4/B). By releasing the handle altogether the descent is stopped
automatically (fig.2/A). Use a second braking carabiner to lower
from a fixed position (fig.4/C). To prevent accidental uncontrolled
descents, the descender may be locked-off entirely by forming a
bight in the free end ofthe rope, passing it through the connecting
carabiner and catching with the bight the entire descender (fig.4/D).
Figure 5: ACCOMPANIED DESCENT
This method of evacuation may only be adopted by rescuers
specifically trained in this technique. No impact loading is tolerated.
The rescuer fastens the descender to his harness and connects the
injured person by means of an additional lanyard. Obligatory is the
use of a supplementary braking carabiner as well as the use of
gloves. The rescuer and the injured person must be secured with
an additional independently anchored safety line.
WARNING: With speeds above 1 m/s during rescue operations the
descender may get hot enough to damage the line.
