Use and Maintenance Manual – A12 JE A15 JE A17 JE A12 JED A15 JED Series
5.1.2. Platform positioning movements
To carry out all movements other than drive, use
proportional levers B, C, D, E, F, G, H and switches I
and L.
To achieve the movement, it is necessary to carry out
the following operations in sequence:
a) Press the dead-man pedal located on the
platform; the green led Z will light up steady
indicating its enabling.
b) Within 10 seconds from the green steady led
lighting up set the proportional joystick control
or the desired switch in the direction shown by
the serigraphy on the control panel.
NOTE: before activating the proportional joystick control or the desired switch the dead-man pedal must be pressed.
Release the “dead-man” pedal and the manoeuvre will be immediately stopped.
The platform positioning controls can be used simultaneously (unless otherwise indicated). Furthermore, the
turret orientation can be operated at the same time as the drive and steering controls in lowered platform
conditions (booms lowered, telescopic boom in, jib at a height between +10° and –70°).
5.1.2.1. Pantograph (lower boom) lifting/lowering
To lift/lower the pantograph (first boom), use the proportional lever B.
Set the proportional lever B forward for lifting or backward for lowering.
5.1.2.2. Upper boom lifting/lowering
To lift / lower the second boom, use the proportional lever C.
Set the proportional lever C forward for lifting or backward for lowering.
5.1.2.3. Jib lifting/lowering.
To lift/lower the JIB, use the proportional lever D.
Set the proportional lever D forward for lifting or backward for lowering.
5.1.2.4. Telescopic boom extension/retraction
To extend/retract the telescopic boom, use the proportional lever E.
Set the proportional lever E forward for extension or backward for retraction.
