> The plates are perforated on the rope trajectory.
> Sharp edges or burrs that can damage the rope or injure the user.
> The handle fails to function.
> The operator's attachment point is thinner than 10 mm.
> The handle tip comes out of the mobile sheave.
> The locking cleat fails to function due to the spring – the device no longer locks on the rope in position.
> The functional test fails: Absence of locking effect while suspended on the ropes (test this aspect on all the
rope diameters that you use.); the handle is no longer functional.
If the cleat, the handle or the spring fails, contact TAZ.
COMPATIBILITY
A fall arrest harness (for example: EN 361:358, 813 etc.) is the only body protection device that can be used
by the user. For the attachment of the device, only use locking carabiners, max. 12cm long, compliant with EN
362, made of aluminium alloy. When used as a fall arrest device, the connection to the fall arrest attachment
point A of the harness should be done directly via a 12cm long connector or indirectly via a TAZ LOV.LINK
connecting lanyard. When used as a descender, the connection to the harness can be done by means of any
max. 12cm long locking connector which is compliant with EN 362.
While in use, always check that the connectors are loaded longitudinally.
The ropes must be compliant with EN 1891:1998 Class A, and have the corresponding diameter (10 to 11mm
for the use in compliance with EN 12841).
Always observe these requirements and length guidelines.
WORKING PRINCIPLE
When the operator is suspended by the equipment via their harness, the tool tips over due to the load. The
rope pivots the mobile sheave, creating a clamping effect at the opposite end, between the two sheaves
B). To release the locking effect: while firmly holding the free rope, the operator opens the handle,
(diagram
and pushes it downwards, in the same direction. If the rope is tight, actioning the handle will make the tool tip
over, and the rope friction will be cancelled.
WARNING:
pressing on the handle without holding the free rope from below is dangerous. It is mandatory to also practice
using the handle release for braking/locking purposes.
SETTING UP THE ROPE
For a normal use on the harness, for rope progression
rope with the attachment point upwards, and the handle downwards. Open the mobile plate and pass the
rope through the longitudinal space between the 2 sheaves
ly on the fixed plate, thus closing the rope inside the LOV2 device. At this stage, check that the cleat holds the
PPE correctly on the rope. You can therefore tap the symmetric connector on the attachment point through the
two plates, and check that the connector is locked.
ANCHORS
The top anchor of the system must comply with the EN 795 standard at 12kN.

(schéma
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 the user risks falling on one or several obstacles in a pendulum in
case it breaks, the lower anchoring point should comply with the EN 795 standard at 12kN.
Also, the angle should be lower than 75° from the horizontal plane.
Calculations should be made to make sure that the load is lower than 3 KN in the anchor points.
OPERATIONAL TEST
For usage in compliance with EN 12841 type A and C, the operational test must be performed after having
installed an independent safety system.
The user will suspend themselves in the LOV2 device and measure its self-locking and descending capacities.
If the device does not lock, do not use it. Immediately contact the manufacturer – TAZ.
OPERATION
Safety system: Once the operational tests are complete, guide the LOV2 device upwards. This is achieved
automatically if the rope is correctly loaded (adapt the loading according 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, use your thumb and your index finger to pull on the plates on the free rope
side of the device, opposite the attachment point.
Left freely on the rope, the LOV2 device will automatically stop the user in case of any failure from the other
locking or progressing systems.
WARNING:
The user should not progress while moving the LOV2 device downwards; otherwise, in case of a fall, the user
risks grabbing the device, which will then start sliding again, impeding the locking process.
Descent: after having performed the functional tests, open and pull the handle of the LOV2 downwards while
using the other hand to hold the free rope where it exits the device
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:
When moving, always hold and brake on the free rope coming out of the device
When overgripping the handle without holding the rope coming out of the device, the user cancels the bra-
king effect of the LOV2 device, and falls.
It is essential to hold the rope coming out of the device, and to practice releasing the handle.
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 ex-
ceptionally 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 tem-
perature (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,
