Connect the ground cable to the cap screw marked
(EN 13463-1:2009).
Assess the range of the work area and, if appropriate, hang the balancer to a roller guide to be able to use it properly in an area wide enough to carry
out the required activities.
If screw-fixing devices are used to install the balancer, use self-locking nuts, split-pins or other safety systems.
In order to avoid anomalous wear, the load must be applied vertically. The balancer must in any case be free to move in its suspension so that it can
line up with the direction of the load.
Where the total weight of the balancer and the packaging is above 25 kg, it must be handled by more than one person or with adequate lifting tools.
The balancer must be installed on a structure having an adequate mechanical resistance. Mechanical resistance of the structure > 5*(Balancer weight
+ Max load).
It is possible to install more than one balancer to the same main structure only if each balancer has an independent connection point and the structure
has a mechanical resistance higher than five (5) times the weight of all balancers plus all maximum loads.
It is possible to install more than one balancer to the same secondary structure (i.e. safety rope) only if each balancer has an independent connection
point and the structure has a mechanical resistance higher than five (5) times the weight of all balancers plus all maximum loads.
When starting up a balancer, we suggest that the following procedure is used:
- Connect the balancer to the main structure through the suspension hook, if present, or fixing hole.
- Connect the safety device to the secondary structure.
- Lift the load to be hanged to the balancer.
- Hang the load to the balancer through the proper hook/snap hook.
- Lower the load by unwinding the balancer’s rope and adjust the stroke limiter clamp to avoid bringing the load above the operator.
- Adjust the balancer strength as long as the hanged load is balanced. Rotate in the direction of the + sign to increase the strength of the balancer.
Rotate in the direction of the – sign to decrease the strength of the balancer.
In case of installation of the balancer at a considerable height, use the dedicated extension ropes to bring the load at the needed working height (the
load must not be above the operator).
Ensure that the working area is adequately lightened to allow a good overview of the operations and of all the equipment, avoiding dark areas, dazzling
and strobe effects.
Warning!!! For all balancers that do not have a suspension hook, make sure that it is fixed to the main structure in such a way as not to block the
movements (oscillations and rotations) which are functional to the correct operation of the balancer itself.
Always connect the safety suspension (S), with exclusive use of the supplied standard fittings (Fig.1),
to a suitably sized support. The safety support MUST NOT BE the same one used for the main suspen-
sion (23) (Fig.1). If the main suspension breaks, the max falling distance must not be more than 100
mm. Tighten the nuts of the clamps 20331 (Fig.1) with a torque of 4 Nm.

To allow the balancer to balance heavier loads within the load capacity accepted, use the specific key to turn screw (41) (Fig.3) in the direction indicated
by the “+” symbol.
For lighter loads, turn screw (41) (Fig.3) in the direction indicated by the “-” symbol.
After adjusting the load, check that the rope can move freely along all its length: the movement must not be limited by the complete winding of the
spring. Check the stroke more than once and according to different speeds.
NOTE: a reduction of the ability of the balancer to hold the hanging load might mean that the drum spring is about to break. DO NOT MODIFY THE
BALANCER ADJUSTMENT TO SUSTAIN THE LOAD ANYHOW, INSTEAD CALL IMMEDIATELY THE SPECIALIZED PERSONNEL AUTHORIZED
TO MAINTENANCE.
Do not use by hanging a maximum load greater than the maximum load allowed and by balancing the same through the regulator.

ATTENTION: when using the balancer, do not exceed the hanging load shifting speed of 0.8 m/s.
ATTENTION: the admissible room temperature interval ranges from +5°C to +60°C.
Grip the tool hanging from the balancer and carry out the required operations. Then accompany the tool as far as it balances, on the vertical line of
the balancer, and release it.
The load to be balanced must be hung on snap-hook (39) (Fig.3). Ensure that the snap-hook is closed correctly after having hung the load.
The cable must never be fully unwound: The work travel must end at least 100 mm before it reaches the lower limit (balancers are fitted with an
automatic end run stop system).
ATTENTION: the electric potential of the hung tool must always be the same as that of the balancer.
If necessary, move and block the clamp (M) (Fig.3) to limit the upward run.
Do not unhook the load if the clamp (M) (Fig.3) does not lean onto the rope’s swaging (POSITION
SHOWN IN FIGURE 3).
- Do not leave the load if it is not in a vertical position;
- Do not swing/throw the hanging load to another operator;
- Do not move the load by pulling the balancer’s rope;
- Do not hang loads that are not within the upper and lower ranges of the admissible load-bearing capacity;
- Do not hang more than one tool on the balancer.
