Safety Devices; Inspections And Maintenance - TECNA 9502 Manual De Uso

- 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 41 (Fig.3) in the direction indicated by
symbol "+". For lighter loads, turn screw 41 (Fig.3) 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.

Safety devices

Drum spring breakage
The balancer is fitted with a safety device that trips when the drum spring breaks and stops the balancer to prevent the hanging
load from falling.
If the hanging tool cannot be lifted or lowered through ordinary strain, DO NOT INSIST but contact customer service.
NOTE: the balancer stops even if the drum spring is fully discharged: in this condition the head of the charge screw 41
(Fig.3) protrudes approximately 4 mm outside the cap. To restore operating conditions, try to charge the spring as
outlined in paragraph "Balancer adjustment". If the balancer does not release, DO NOT do anything and contact
customer service.
Manual lock
The balancer is fitted with a manual-locking system (Fig.4): turn the knob (6) to position (A) to stop drum rotation. Turn the knob
(6) to position (B) for routine work conditions.
NOTE: for safety reasons, the shape of the shutter that stops the drum does not allow the shutter to be removed
unless it is perfectly coaxial with the matching hole in the drum: to release the drum, move the load slightly at the top
and at the bottom until you find the correct position in which to release it.
OPTION 'B': control from below (Fig.2)
Lower the side of the handle with the RED tape to lock the drum; lower the side of the handle with the GREEN tape to release it.
WARNING: do not leave the balancer with the drum locked and no hanging loads.
WARNING: if the balancer's cable is not fully wound, and no load is applied to it, DO NOT do anything but
contact the customer service at once.
WARNING: always comply with the safety regulations when using electrical appliances.

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 (23) and S (Fig.1), the fixing screws & self-locking systems (if used), and the condition of the hooks and cable.
If the cable has the defects shown in (Fig.5), 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 spare parts will negatively affect safety and performance and will, in any case, void the warranty.
