If any of the following damages or faults occur, the product must be retired or sent
back to TAZ.
Signs of corrosion that affect the parts (the signs do not disappear if you try to lightly sand
them).
Absence of the locking effect while suspended on the ropes (test this aspect on all the rope
diameters that you use).
Cracks in any of the parts and/or the following faults:
the two plates come in contact forcefully at the attachment point
>
the mobile sheave does not move freely and/or there is a clearance on its axle
>
the fixed sheave has a clearance on the fixed plate
>
the clearance between the fixed and mobile sheaves and the plate is higher than 5 mm
>
(diagram H)
clearance between the rivets and the fixed plate
>
the mobile plate is not locked by the head of the rivet
>
the stoppers have a clearance.
>
the push button does not come out of its groove more than 6 mm because of the spring
>
or because it is blocked; the mobile plate may not lock
Friction wear on the sheaves caused by the rope
degraded sheave guide grooves
>
holes in the sheave edges (hollow parts)
>
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.
Material around the connexion 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.)
If the cleat, the handle or the spring fails,not use LOV3 anymore and contact TAZ.
COMPATIBILITY
A full body harness compliant with EN 361 is the only harness that can be used by the user.
The same harness can be compliant with EN 813, a validation that is necessary for posi-
tioning while working, to be able to use LOV3 as a locking device and as a descender. For
the attachment of the device, only use locking carabiners compliant with EN 362 (length
max. 12 cm), 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 connector
24
(diagram A, (6))
in its groove
(diagram
D).
or indirectly via a lanyard, TAZ LOV.LINK. When used as a descender and locking device,
the device can be attached on the harness via a connector that is compliant with EN 362
(length max. 12 cm).
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 worker 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
(diagram
free end of the rope, open the handle, and push 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 :
Always hold the free end of the rope when pushing down on the handle. It
is mandatory to practice using the handle release for braking/locking purposes.
SETTING UP THE ROPE:
(diagram C, D and E)
For a normal use on the harness, for rope progression : the fixed plate must be placed on
the rope with the user's attachment point upwards, and the handle downwards. Open the
mobile plate and pass the rope through the longitudinal space between the 2 sheaves.
Close the mobile plate symmetrically on the fixed plate, thus closing the rope inside the
LOV3 device.
At this point, you have to:
> Check that the cleat holds the PPE correctly on the rope.
> Check that the connector is clipped correctly onto the attachment point, through the two
plates, and check that the connector is locked.
> Check that the spring-based locking push button is correctly engaged in the locking hole
of the mobile plate, and that it locks it firmly.
PAY ATTENTION TO AVOID CLOSING THE MOBILE PLATE INCORRECTLY .
To remove the rope, the user opens the mobile plate by pressing down on the push but-
ton, and by rotating the mobile plate so that it opens the longitudinal space between the
sheaves.
WARNING:
This double action can occur accidentally; pay special attention to the area
of the push button.
B). To release the locking effect, firmly grasp the
