Safety Devices; Inspections And Maintenance - TECNA 9423 Manuel D'utilisation

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 44 (Fig.5)
protrudes approximately 4 mm outside the cap. To restore operating conditions, use the lever 5 (Fig.6) and try to charge the spring
as outlined in paragraph "Balancer adjustment" (release lever 5 when the head of the charge screw has re-entered the cap). If the
balancer does not release, DO NOT do anything and contact customer service.
Centrifugal speed limiter
The balancer is fitted with a centrifugal safety system that locks the drum if the speed exceeds the danger limit (accidental unhooking of the
load, cable breakage, etc.).
If the centrifugal safety system trips, discharge the drum spring IMMEDIATELY and completely, and have the balancer inspected by an
authorized service center.
Manual lock
The balancer is fitted with a manual-locking system (Fig.4): turn the knob 1 to position H to stop drum rotation. Turn the knob 1 to position
G 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.
OPTION "RI", insulated rotary suspension (Fig.3)
Permits to insulate the load hung on the balancer and/or turn the hanging tool freely without twisting the cable.
WARNING: always comply with the safety regulations when using electrical appliances.
Installation: insert the snap-hook (33) into the pin E of the rotary suspension. Insert the cable's thimble (15) into the pin F; insert the split-pin
(D) and deform it.

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.7), 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 spare parts will negatively affect safety and performance and will, in any case, void the warranty.
