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).

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).
- Unhook the load from the balancer
- Hook the new load; bring it to a vertical position below the balancer with the rope stretched.
- 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.
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 suspen-
sions (A) 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.4 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.

aintenance
Maintenance may be carried out only by skilled and authorized personnel.
Use original DOGA spare parts only. When requesting spare parts, the Customer should kindly contact the supplier of the
balancer or the manufacturer directly, specifying the equipment's identification data printed on the plate.
Do not make any modification to the rope group and, specifically, DO NOT SHORTEN the rope: if needed, please get in touch with
the supplier or the manufacturer directly.
Never disassemble the balancer. Maintenance is to be carried out only by skilled, authorized personnel.
W
arranty
The use of non-original DOGA spare parts will negatively affect safety and performance and, in any case, it will void the warranty.
The rope and the drum-spring are not covered by warranty.
d
isposal
At the end of the work life of the balancer, proceed as follows:
- Rewind the rope completely
- Unhook the load from the balancer
- Unhook the balancer from the primary and safety connections.
- Proceed to fully discharge the balancer spring.
Once the balancer has been discharged, it must be disposed of complying with the rules and regulations in force.
