RECALL : Obeying the machine's usage and maintenance instructions
will help to avoid the majority of incidents. Nevertheless these
may happen, and before any work is carried out, it is vital to
check the table in chap. 6, page 51 to see if these are
reported. In this case, you simply need to follow the
instructions.If not, you should contact your HAULOTTE agent
or the After Sales Service of the manufacturer.
Before diagnosing the breakdown, you should check that:
• the fuel tank is not empty,
• the batteries are correctly charged,
• the emergency stop punch buttons on the turret and the platform are
unlocked,
• the relays (platform control lectern - turret cabinet) are correctly inser-
ted into their socket,

NOTE : In the turret cabinet, LEDs show the status of each extension
to check that this is properly activated.
