INTRODUCTION
Before using the batteries, make sure that both ends of the cables are connected to the terminals as
•
prescribed: (+) with (+) and (-) with (-).
Do not short-circuit the terminals.
•
The gas released when charging is highly flammable. When charging, leave the battery compartment
•
uncovered for more effective ventilation and take off the plugs.
Never check the battery charge with "jumpers" obtained by putting metal items on the terminals.
•
Before taking any action, check that no elements are shorted.
•
Always disconnect the battery before working on the electrical system.
•
For battery chargers and similar equipment, use solely auxiliary power sources with an effective ground
•
connection to avoid any electric shocks.
Fluid passing through a very small orifice can be virtually invisible and have sufficient force to penetrate
•
under the skin; in such cases, having to make a check, use a card or a piece of wood.
Having to check the system pressure, use the specific instruments.

BELTS, ROPES AND SUSPENSION ELEMENTS: USER ADVICE
Keep a record of all the suspension elements used, stating the characteristics of the suspension ele-
•
ments and the data given on the identification plate .
Never leave belts, cords or suspension elements in use whose identification plate has been lost.
•
Always use belts, ropes or suspension elements of suitable dimensions. Concerning the suspension
•
elements, take into consideration the lifting angle and any unbalancing of the load.
The bells on the suspension elements must be sized in proportion to the hook of the overhead travelling
•
crane and anyhow must be free to move easily.
Always rest the load in the race of the hook.
•
Never load the tip of the hook.
•
When lifting, avoid sudden operations that can jerk on the ropes and belts.
•
Never do any lifting with the ropes and belts twisted.
•
Knots are not permissible. Always protect the ropes and belts when they come into contact with sharp
•
edges.
When moving with no load, to prevent impact and accidental hooking, hang the hooks in the bells and
•
close the safety ones.
Using suspension elements under conditions of unbalanced load
If lifting unbalanced loads it is advised as a precaution to downrate the load capacities of the lifting ele-
ments:
Slings with 2 booms, consider them as corresponding to 1 boom.
•
Slings with 3 and 4 booms, consider them as corresponding to 2 booms.
•
Tips for maintenance
Periodically examine the belts, ropes and suspension elements according to current legislation to define
their state of service.
Change them in the following cases:
When the components show: deformation, cracks, hollows, cuts or abrasions.
•
When the wear of the components exceeds 10% of the original dimensions.
•
When the sling shows signs of overloading.
