Use and Maintenance Manual – A12 JE A15 JE A17 JE A12 JED A15 JED Series
5.1.1. Drive and steering
Before carrying out any displacement operation, verify that no people are in proximity of the machine and in
any case proceed with the utmost caution.
IT IS FORBIDDEN to drive the machine when the platform is lifted unless the chassis is flat and steady with no
holes and steps.
To drive the machine carry out the following operations in sequence:
a) Press dead-man pedal ZF located on the platform; the green led ZA will light up steady indicating its enabling.
b) Within 10 seconds from the green steady led lighting up, set the proportional joystick control A forward for forward drive or
backward for reverse drive.
WARNING!!
Drive and steering controls can take place at the same time but they are interlocked with the platform
movement controls (lifting/lowering/rotation). With platform lowered (booms down, telescopic boom in, jib at a
height between +10° and –70°) simultaneous steering-drive-turret rotation is possible to facilitate the machine
positioning in narrow spaces.
With platform lowered (booms down, telescopic boom in, jib at a height between +10° and –70°) it is possible to select different
drive speeds by means of the speed selector T.
NOTE: To achieve maximum drive speed, set the speed selector (T) to position (III), and press down the proportional joystick (A).
To operate on high ascending slopes (e.g. while loading the machine onto a truck) set the speed selector (T) to position (II).
To operate on high descending slopes (e.g. while unloading the machine from a truck) and get the minimum speed with lowered
platform, set the speed selector (T) to position (I).
With platform lifted the safety drive speed is automatically activated. Drive can be controlled with raised
platform only if both pot-hole guards are fully lowered. Otherwise, drive with raised platform is disabled and
the condition is reported to the operator by turning on the red led ZD (without triggering an audible alarm).
To steer, press the buttons V / Z located on the drive proportional joystick control (press the right button for right steering and vice
versa). Also the steering control is enabled by the “dead-man” pedal and it is possible only if the green led ZA is lit up steady.
