it from falling and UNLOAD THE SPRING COMPLETELY;
- if for any reason whatsoever the balancer does not rewind the cable, DO NOT do anything on your own initiative but contact the customer service at once;
- never release the load if the cable has not been fully wound in the drum;
- should you find the balancer with the cable unwound and no load applied to it, DO NOT do anything on your own initiative but contact customer service at once.
Adjusting the balancer
To enable the balancer to balance heavier loads, use wrench D to turn the knob 6 counterclockwise, identified by symbol "+" as shown in the figure (Fig.2). For lighter
loads, press the end of the spring 9 (Fig.3) and turn it clockwise, identified by symbol "-" as shown in the figure (Fig.3).

the load-decreasing direction).
After having adjusted the load, check that the cable slides freely for its entire length: the movement must not be restricted when the spring has wound all the way.
Check the stroke often and at different speeds.
ONLY FOR models 9346-50
Balancers 9346-50 are fitted with a mechanism that locks the rewinding of the cable. This permits working without the cable traction, for instance inside a car (Fig. 7).
The locking is achieved through the slow upward movement of the tool.
In order to release the rotation of the drum, pull the tool slightly downwards but make it go back up quickly.
In order to prevent undesired locking, it should go up at a suitable speed.
The locking kinematism may be neutralized by tightening the screw (25) all the way while the load goes up and down (Fig. 6).
NOTE: should the balancer's capacity of supporting a hanging load decrease, this could mean that the spring of the drum is about to break. DO NOT
MODIFY BALANCER ADJUSTMENT TO MAKE IT HOLD UP THE LOAD IN ALL CASES BUT CONTACT SKILLED PERSONNEL IN CHARGE OF MAINTENANCE AT
ONCE.
Safety devices
The balancer is fitted with a safety device that trips if the drum's spring breaks and stops operations to prevent the hanging load from falling.
If you are unable to move the hanging tool up or down using moderate force, DO NOT continue but contact our technical service at once.
NOTE: the balancer locks even if the drum spring is completely discharged. To restore working efficiency, attempt to charge the spring as outlined in
paragraph "Adjusting the balancer". If the balancer does not release, DO NOT do anything but contact the technical service at once.
INSPECTIONS AND MAINTENANCE
Maintenance may be carried out only by skilled and authorized personnel.
- The user must visually inspect the balancer on a regular basis (such as, for instance, at each work shift) especially to check the state of suspensions A and S (Fig.
1), the fixing screws and the self-locking systems (if used), and the condition of the hooks and cable.
Should the cable have the defects shown in Fig.8, replace it immediately.
Do not make any modification to the cable unit and, specifically, DO NOT SHORTEN the cable: if need, please get in touch with TECNA S.p.a.
- check that the cable'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.
Never disassemble the balancer. Maintenance is to be carried out only by skilled, authorized personnel.
The balancer must be disposed of complying with prevailing rules and regulations at the end of its work life.
Warranty
The use of non original TECNA S.p.a. spare parts will negatively affect safety and performance and will, in any case, void the warranty.
