ANCHORS:
The top anchor of the system must comply with the EN 795 standard at 12kN.
WARNING:
it is essential that the anchor point is placed above the user's position, and
that the rope is as tight as possible. Always use the device so that a fall is avoided.
When using a diagonal or tight rope, and where there is a risk of breaking the an-
chor point, and the user falling on one or several obstacles, the lower anchoring
point should comply with the EN 795 standard at 12kN.
Also, the angle should be lower than 75° from the vertical.
Calculations should be made to make sure that the load is lower than 3kN in the anchor
points.
OPERATIONAL TEST
For usage in compliance with EN 12841 type A, B, and C, the operational test must be
performed after having installed an independent fall arrest system.
The user tests the capacity of the LOV3 device to progress up on the rope. The user will
then suspend themselves in the LOV3 device and measure its self-locking and descending
capacities. If the device does not lock, do not use it. Contact the manufacturer TAZ.
OPERATION:
> Safety system: once the operational tests are complete, guide the LOV3 device upwar-
ds. This is achieved automatically if the rope is correctly loaded (adapt the loading accor-
ding to configurations and types of rope) or if the rope is heavy enough, in tension or tied
at the bottom end. To guide the device upwards, hold the free end of the rope at the bottom
and pull the device upwards.
To guide the device downwards
(diagram
on the plates on the free rope side of the device, opposite to the attachment point.
Left freely on the rope, the LOV3 device will automatically stop the user in case of any
failure from the work positioning device.
WARNING : the user should not progress while moving the LOV3 device downwards;
otherwise, in case of a fall, the user risks grabbing the device, which will then start sliding
again, impeding the locking process.
> Locking function : once the operational tests are complete, guide the LOV3 device
upwards automatically; the rope must be loaded accordingly (adapt the loading according
to configurations and types of rope) or heavy enough, in tension or tied at the bottom
end. To guide the device upwards, hold the free rope and pull the device upwards. To use
the locking and positioning functions of the device, load the attachment point. While sus-
pended by the locking device, the user can release it by using its descending function,
following the procedures.

J), use your thumb and your index finger to pull
> Descending: once the operational tests are complete, hold the free end of the rope
coming out of the device with one hand, and open and pull the handle of the LOV3 de-
vice downwards
(diagram O)
with the other hand. The desired speed will be attained by
adjusting the traction on the handle, and by braking with the other hand on the free rope
coming out of the device. Do not exceed a speed of 1m/s, otherwise the stainless steel of
the sheaves can overheat and alter the friction, and therefore the locking effect. For safety
reasons, the user will guide the fall arrest system on the rope.
WARNING:
while descending, always hold and brake on the free rope coming out of
the device
(diagrams F, G, I,
O).
When overgripping the handle without holding the rope coming out of the device, the
user cancels the braking effect of the LOV3 device, and falls.
It is essential to hold the rope coming out of the device, and to practice releasing the han-
dle.
When the tool locks on the rope, make sure the handle is properly folded back to avoid
an accidental release. Even with the handle folded back, a significant pressure applied
downwards on the closed handle can exceptionally release it. Pay special attention to this
area. For increased safety, the user can tie a stopper knot.
The operation of the device is optimal when the usage conditions are normal, with low
humidity, average temperature (5°C to 25°C), away from sources of dust and grease. When
conditions are not favourable (extreme humidity and heat, rain, frost, dust, grease, etc.),
there is a risk of losing the control while descending, or to damage the rope. Additional
precautions (locking tests, braking aid via a friction connector, speed reduction, building
several anchors for the descent, etc.) should be taken.
There is no limit to the number of descents or the height of the descent. In case of a rescue
though, there is an exception. Please see the downloadable rescue tutorial on taz3d.fr.
WARNING :
when used as a fall arrest device, the falling distance should be calculated:
> firstly, because the LOV3 device can slide before locking, for up to 2 m when used cor-
rectly.
> secondly, because the elasticity of the rope will depend on the length that separates the
LOV3 device from the anchor point above.
