READ THIS NOTICE CAREFULLY
This device was designed to offer you the degree of safety expected from
personal protective equipment in accordance with the Directive
89/686/EEC.
SAFETY MEASURES AND WARNINGS
a) There are innumerable and even unimaginable possible modes of use
of this device. Only techniques shown in the figures that are not
crossed out or displaying a skull are recommended and covered by
the warranty.
b) This product must be used exclusively by adequately skilled persons
otherwise the user must be constantly supervised by trained
personnel, who must guarantee for the safety. This includes liability
against damages, injuries and death incurred by improper use
or misuse of the equipment.
c) This product may be used combined with personal protective
equipment conforming to Directive 89/686/EEC and compatibly with
the relevant information.
d) Lifetime of this product will be extended if it is used with care. In
particular avoid rubbing against abrasive surfaces and/or sharp
edges.
e) Primary function of the descender is progression along a working line,
and is not suitable for use in a fall arrest system. It must always be
used in conjunction with a fall-arrest device on an independent safety
line.
f) The braking action of the device and thus your safety may be
considerably reduced if the device or the rope is dirty, oily, muddy or
icy.
g) Prolonged use in salty environments (e.g. sea cliffs) may affect the
performance of the product.
h) Do not expose the device to significant heat or cold (see work and
stock temperature).
i) Avoid any contact with chemical reagents as they may affect the
performance of this product. Contact the producer if in doubt.
j)
The descender device should never be left in place (specifically
outdoors) e.g. at a workstation because of the weathering
deterioration of the rope.
FUNCTIONING PRINCIPLES
Figure 1: INSTALLATION OF THE ROPE
The descender can either be attached to the harness concordant with
either EN 361, EN 813 or EN 12277 (fig.4/A - the operator slides with the
descender along the rope) or it can be fastened to an anchor (fig.4/C – the
i
rope slides through the non-moving descender). To install the descender
on the rope, first form a bight on the rope (fig.1/B). The handle of the
descender has to be pushed in its extreme open position and the jamming
cleat has to be drawn out of the descender to its terminal point. Now the
bight can be pushed in between both flanges at their lower end (fig.1/A),
that is, 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 test-
loading 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 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 of the rope, passing it through the
connecting carabiner and catching with the bight the entire descender
(fig.4/D).
