The sole risk linked to the use of the balancer consists in any uncontrolled rewinding of the tube. 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
Should one wish to fully discharge the spring, stop the discharging operation as soon as the spring is effectively and completely
discharged (proceeding beyond this position would damage the spring which would require to be replaced).
- if for any reason whatsoever the balancer does not rewind the tube, DO NOT do anything on your own initiative but
contact the customer service at once;
- never release the load if the tube has not been fully wound in the drum;
- if the balancer's tube 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 allow the balancer to balance heavier loads, turn the knob 4 as shown in Fig.2 (counter clockwise, identified by the
+ symbol. The adjustment is not continuous – it is jerky): after every jerk, knob 4 must touch the plate 5 Fig. 2. As
concerns lighter loads, pull out knob 4 and, grasping it firmly, turn it as shown in Fig. 3: after every jerk, the knob
must touch the plate 5 Fig. 3.
After having adjusted the load, check that the tube 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.
INSPECTIONS AND MAINTENANCE
Maintenance may be carried out only by skilled and authorized personnel.
- Visually inspect the balancer on a regular basis (for instance once at each work shift). Specifically, check the state of the suspensions A and
S (Fig.1), the fixing screws & self-locking systems (if used), and the condition of the tube and the pneumatic fittings.
- check that the tube'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 static and dynamic tests (Machinery Directive 2006/42/EC, Annex I, section 4.1.3) have been performed by the manufacturer.
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 spare parts will negatively affect safety and performance and will, in any case, void the warranty.
The 9203 balancers are not equipped with the safety device, contemplated by Standard DIN15112, which should trip if the drum's spring
breaks.
