ATTENTION: if the balancer must work in contact with chemically aggressive powder, liquid, or
gas, verify chemical compatibility by calling TECNA spa.
Assess the total load to be balanced: tool, accessories and sections of hoses or cables to be lifted by the balancer. The overall load to be
balanced must fall within the balancer's minimum and maximum load-bearing capacity.

Connect the ground cable to the cap screw marked
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.
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 suspension (33) (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 (9) (Fig.4) in the direction
indicated by the "+" symbol. For lighter loads, turn screw (9) (Fig.4) 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 (29) (Fig.4). 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.4) to limit the upward run.
