TECNA 9422 Manuel D'utilisation page 4

Install the balancer before using it. This operation is to be carried out by skilled personnel who must comply with the directions
outlined in this manual: a wrong installation could cause injury/damage to people/property.
This manual contains important information that the user must adhere to in order to use the balancer safely. Be sure to
have clearly understood all the instructions before using the balancer. Failure to do so could cause injury.
The balancer was built in conformity with European Community Directives that were pertinent and applicable when the balancer was put on
the market and that entail the CE marking of the product.
Intended conditions of use
The balancers are designed to balance the weight of tools and utensils in general and are to be used by one operator at a time. The
balancer may be used in an assembly line, in single workplaces, in professional or private environments, as a hobby, etc.
Always operate, inspect and maintain this balancer in perfect working order in accordance with all regulations pertinent to balancers,
tools and workplaces.
Use contraindications
Do not use the balancer in environments with potentially explosive atmospheres.
Do not permit children or people under age to use the balancer.
Do not work, transit or linger underneath the balancer.
When using balancers, always fully and duly comply with the standards and laws in force in the country in which they are used.
TECNA S.p.A. will not be held liable for any damage or problems caused by customers using these balancers for any other application.
Choosing the balancer
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.
Starting up the balancer
Assess the range of the work area and, if need be, hang the balancer on a carriage 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.
Always connect the safety suspension S, using exclusively 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 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) at a torque of 4 Nm.
To avoid anomalous wear, the load must be applied vertically and in any case the cable must be free to line up with the direction of the load.
Using the balancer
Grip the tool hanging from the balancer and carry out the required operations. Then accompany the tool until it balances, on the vertical line
of the balancer, and release it.
The load to be balanced must be hung on snap-hook 33 (Fig.5). Ensure that the snap-hook is properly closed after having hung the load.
The cable must never be unwound all the way: its work travel must end at least 100 mm before it reaches the lower limit (balancers
9422÷9426 9451÷9456 are fitted with an automatic limit stop system).
If need be, move and lock the clamp 32/34 (Fig.5) to stop the upward stroke.
When using the balancer, always don individual protective gear and closely adhere to the prevailing accident prevention regulations.
It is strictly prohibited to:
- Abandon the load if it is not in a vertical position
- Swing/throw the hanging load to another operator
- Move the load by pulling the balancer's cable
- Hang loads that are not within the upper and lower ranges of the admissible load-bearing capacity
- Hang more than one tool on the balancer
The sole risk linked to the use of the balancer consists in any uncontrolled rewinding of the cable. This very dangerous event will
be avoided by adhering to the following instructions:
- if you have any doubts concerning the working efficiency of the balancer, BEFORE performing any kind of inspection be sure to hold up the
hanging tool to prevent it from falling and DISCHARGE 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
- if the balancer's cable is 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 the specific key to turn screw 44 (Fig. 5) in the direction indicated by symbol "+". For
lighter loads, turn screw 44 (Fig. 5) in the direction indicated by symbol "-".
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.
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.
