3.13 O UTRIGGER JOINT LOCK PINS
The outrigger joints have locking pins with spring return.
The pins enter their seats pushed by the force of the spring
both in the transport and stabilisation position.
Check positioning of the pins in their seat and the force of
the spring after every rotation of the outrigger.
3.14 A RMS POSITION SENSORS
The cylinders of the 1st‑2nd arm and that of the 3rd arm are equipped with an internal posi‑
tion sensor that allows the circuit board to know the position of the cylinders and adjust the
speed.
The electric connection of the sensors is visible on the bottom of the cylinders.
When one of the two sensors is broken or its signal no longer reaches the main circuit board
an icon appears in position 7 of the remote control. (paragraph 4.2.1 display main visualiza‑
tion).
If the first arm sensor is broken, the machine will continue to work. If the third arm sensor is
broken, the aerial part will block.
If one or both sensors should break, contact the JLG after‑sales service.
