plus all maximum loads.
- Connect the safety device to the secondary structure.
- Lift the load to be hanged to the balancer.
- 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.
to block the movements (oscillations and rotations) which are functional to the correct operation of the balancer itself.
(Fig.1), to a suitably sized support. The safety support MUST NOT BE the same one used for
the main suspension (25) (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.

For lighter loads, turn screw (45) (Fig.5) in the direction indicated by the "-" symbol.
winding of the spring. Check the stroke more than once and according to different speeds.
Spring complete unloading
You can fully unload the spring by turning with the appropriate key in the direction indicated by the sign "-".
WARNING!!! The spring is unloaded when the screw comes out of the housing by 4 or more mm
(Fig.5). Stop spring unloading to avoid damage to the balancer.
Do not use by hanging a maximum load greater than the maximum load allowed and by balancing the same through the regulator.

SING HE ALANCER
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 (35) (Fig.5). Ensure that the snap-hook is closed correctly after having hung
the load.
If necessary, move and block the clamp (M) (Fig.5) to limit the upward run.
Do not unhook the load if the clamp (M) (Fig.5) does not lean onto the rope's swaging (POSITION
SHOWN IN FIGURE 5).
- 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.
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.
