KONG Italy BACK-UP, Manual

Page: 30 / 98

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” (fall-arrester): the “BACK UP” is
free to move in both directions. In this case the
“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” (positioning): the “BACK UP” sli-
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).
The selection between “FREE MODE” and “LOCK
MODE” is made by moving the lever; the lever is
fitted with a locking button; to unlock, push down the
button
- move the lever to desired position - check that the
button returns in back-up position and locks the lever
movement (fig.7).
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!
