HOW DOES IT WORK?

The retractable type fall arrester must be attached to a reliable anchorage by its carabiner.
The automatic carabiner situated at the end of the cable or of the strap must be attached to
the attaching point of the fall arrest harness. During the ascent and/or the descent of the user,
the cable will be kept in tension by the retracting spring integrated into the equipment. In event
of a fall, the clamping internal system will stop the cable uncoiling thanks to the activation of a
calibrated lock which will stop the fall in optimal conditions. The equipment is adjusted in factory
so, to keep its results, under no circumstances its adjustment must be changed.
THE CHANGE OF AN ADJUSTMENT WOULD MAKE THE EQUIPMENT DANGEROUS.
CHECKING BEFORE USE
Before each use, carry out a thorough visual examination to ensure that thePPE, as well as any
other equipment with which it could be associated (connector, lanyard...) is complete. Make all
necessary arrangements for the implementation of any rescue in total safety. In the event of your
product being damaged, consult the manufacturer or his agent. If you have any doubts regarding
the safe condition of the product, or if the product has been used to arrest a fall,it is essential to
your personal safety that the PPE be withdrawn from service and sent back to the manufacturer
or a qualified repair centre for checking, or destruction. Following examination, the centre will
either deliver or refuse written authorisation to re-use the PPE. It is strictly forbidden to modify
or repair a PPE yourself. Only the manufacturer or a repair centre is qualified to carry out these
repairs (fig. 1.1). When the system is delivered with an integrated equipment, it is forbidden to
replace one of the components of this system.
Carefully check the following points :
► All the cable or the webbing winds out and in freely.
► The braking function operates by giving a quick tug on the cable. The cable should brake
immediately. (Picture 1.2)
► The device is in good condition and the screws and the closing rivets are present and suit-
ably fixed.
► The extremity of the cable or the webbing is suitably swaged or sewed.
► The carabiners provided with the device function and lock correctly.
► There is no trace of corrosion on the metallic parts.
► The cable or webbing does not show any sign of wear(tear, fraying, breaking, corrosion,
etc...) (Picture 1.3)
NOTE
Self-retractable fall arresters are designed essentially to operate in a vertical position. However,
Some models are also capable of opera-ting in the horizontal position (for confirmation, contact
the maker of his agent). But, before installing, it is highly advisable to check there is no risk of
pendulum movement and to protect the cable from any cutting edges or abrasive surfaces. For
retractable fall arrester fitted with a fall indicator, check before use that the fall indicator has not
been activated. Its activation demonstrates that the device has been subjected to a fall or a
significant traction force. In this case, the device must be returned to the manufacturer or to a
certified repair centre for checks (Picture 2).
USE
Connection:
► The retractable type fall arrester can be connected to a reliable anchorage point by its
anchorage connector.
► The connector situated at the end of the cable or of the strap of the equipment must be
connected to the fall arrest anchorage point of the harness.
