Warning:
- when working at a height, suspended to an adju-
stment device inserted on the WORKING ROPE, al-
ways use at least a second SAFETY ROPE with
inserted a fall-arrester device conforming to EN 12841
type A or EN 353 norms,
-
when positioning the device, make sure that:
-
anchor points of working and safety ropes are pla-
ced above the user and conforming to EN 795 norm,
-
connectors have a gate locking systems and con-
form to EN 362 norm,
-
the rope between anchor point and user is not
loose,
-
remaining in a safe position, check that the device
is working properly, every time you use it,
-
the device performance may differ from the perfor-
mances specified in the norms if used with different
ropes,
-
humidity, snow, ice, mud, dirt, etc. greatly reduce
(up to nullifying) the performances of the devices.

16.2 - Function modes
Select the function mode before inserting the "BACK
UP" on the rope, according to the intended purpose:
-
"FREE MODE"
free to move in both directions. In this case the
(fall-arrester): the "BACK UP" is
"BACK-UP" shall be connected directly to harness
via the supplied connector (fig. 2). It may be neces-
sary to insert a second connector for a 90° rotation
of "BACK-UP" (fig. 3). Warning: in this mode do
not place a simple longe between device and
harness: risk of death! (fig. 4); if the distance bet-
ween safety rope and working rope implies the use
of a longe, only a longe fitted with a shock ab-
sorber conform to EN 355 norm shall be used
(fig. 5).
-
"LOCK MODE"
des in one direction only (upwards). Warning: the
device is not a fall-arrester in "LOCK MODE" there-
fore: you shall not overpass the "BACK-UP" and
you shall use a longe of convenient lengths so
that the height of a potential fall will always be
less than 0.5 m. (fig. 6).

- move the lever to desired position - check that the
button returns in back-up position and locks the lever

Warning: like other systems and self locking knots
e.g. "Prussik" the "BACK-UP" blocks only if the
load is applied to the connector only: never load
the "BACK-UP" IN ANY OTHER WAY, as for exam-
ple in figures 8 and 9: "BACK-UP" WILL SLIDE
ALONG THE ROPE: DANGER OF DEATH!
(positioning): the "BACK UP" sli-
is made by moving the lever; the lever is
