The highest risk linked to the use of the balancer consists in the uncontrolled rewinding of the rope.
1 If, for any reason, the rope is not rewound by the balancer, DO NOT intervene and call immediately the maintenance service;
2 Never unhook the load if the rope is not completely wound in the drum, prevent the rope from touching the rope-guide.
3 Should you find the balancer with the rope completely unwound and no load attached, DO NOT intervene and call immediately
the maintenance service;
4 During use, the rope must be straight and must not be in contact with any pulley, ring or external structure close to the place where
the balancer is installed and used;
5 The use of the balancer is allowed only with its rope in a vertical position.
6 The adjustment of the balancer stroke must be done so to ensure the positioning of the tool at a height equal or lower to that of
the operator, notwithstanding the place where the balancer is installed.
7 Do not twist (beyond 360°) the rope during use, if the load must turn during operation then provide that the dedicated tool is used.
8 Should the balancer be provided with a locking device, use it when the tool hung to it is not used (end of work shift).
After the intervention of the devices that avoid the load fall or the uncontrolled rewinding of the rope, a revision
of the balancer is necessary. To this end, contact your dealer.
When the balancer is used with an electrical tool, please refer to the user manual of the electrical tool for the
management of eventual residual risks.
Do not use the balancer by holding it from the rope; hold only the snap-hook or the hanged tool.

If the balancer is provided with no locking device, before proceeding with the tool change, it is necessary to rewind completely the
balancer rope without using the stroke adjustment device as a locking device.
Should the balancer be provided with locking devices, it is also possible to proceed as follows:
- Activate the lock (visible red indicator or closed padlock).
- Sustain the load in a different way (not through the balancer rope).
- Unhook the load from the balancer
- Hook the new load; bring it to a vertical position below the balancer with the rope stretched.
- Deactivate the lock (visible green indicator or open padlock) paying attention to the possible vertical movement of the new applied
load.
- Adjust the balancer, if needed, to balance the new load (when the new load has a different weight).
Do not move away from the balancer if a load is not hooked and the locking device is activated (visible red
indicator or closed padlock).
I
nspectIon
The balancer must be visually inspected on a regular basis (e.g. once at each work shift). Specifically, check the state of the
suspensions (33) and (S) (Fig.1), the fixing screws and self-locking systems (if used), and the condition of the hooks and cable.
To check the cables, regarding rejection criteria (cable replacement), refer to ISO 4309:2011. (See Fig.5 for some
examples).
- check that the rope's movement is smooth and that it does not make any strange noises;
- do not lubricate the balancer with flammable or volatile fluids;
- do not remove any labels. Replace any damaged labels;
- the balancer must be inspected at least once a year by skilled, authorized personnel.
In case of unusual behaviour of the balancer, contact your dealer.

Drum spring breakage
The balancer is fitted with a safety device that trips if the drum spring should break; it blocks operation, preventing the load hung
from falling.
If the hanging tool cannot be lifted or lowered through ordinary strain,
DO NOT INTERVENE BUT CONTACT THE AFTER-SALES ASSISTANCE SERVICE.
NOTE: the balancer stops even if the drum spring is fully discharged: in this condition the head of the load screw (9) (Fig.4) protrudes
by approximately 4 mm outside the cap. To restore operating conditions, try to load the spring as outlined in the "Balancer adjustment"
paragraph. If the balancer does not release
DO NOT INTERVENE BUT CONTACT THE AFTER-SALES ASSISTANCE SERVICE.
