7.21 FIVE‑YEARLY INSPECTION
The replacement of the cables and pulleys is advisable every 5 years, even in shorter time
according to the working hours.
Further inspections of the extension system are required in the following situations:
• Machine exposed to extreme environmental conditions (for example low temperatures,
sea environments, etc.).
• Incorrect movement of the arms or noises caused by the movement of the extensions.
• Unused machine for long periods.
• Overloaded machine or subject to collisions.
• Machine subject to short circuit, the ropes could be damaged internally.
Remember that in all cases the Constructor envisions a mandatory check of the entire
machine, including ropes and pulleys, every 1000 hours of use, which must be performed
at a JLG certified assistance centre.
