Inspections And Maintenance - TECNA 9300 Manual De Uso

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 UNLOAD 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 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 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 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.

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.4, 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 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 S.p.a. spare parts will negatively affect safety and performance and will, in any case, void the
