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!!
In standard machines the drive and steering controls can be executed simultaneously but they are
interlocked with the platform movement controls (lifting/lowering/rotations) except four wheel drive Diesel
machines (D-4WD) where with platform lowered (booms down, telescopic boom retracted, jib at height
from +10° to
– 70°) only simultaneous drive-steering- turret orientation is allowed to help machine
positioning in narrow places.
In machines with simultaneous controls (OPTIONAL) the drive and steering controls can be executed
simultaneously but they are interlocked with the platform movement controls (lifting/lowering/rotations) as
previously; on the other hand the simultaneous drive-steering-orientation with platform lowered (booms
down, telescopic boom retracted, jib at a height from +10° and -70°) is allowed in all three versions (electric
“E”, electro - diesel “ED” and four wheel drive diesel RTD).
With platform lowered (booms down, telescopic boom in, jib at a height b10° and – 70°) it is possible to select different
drive speeds by means of the speed selector T and/or the differential lock button ZG . Due to the rigid chassis of the machine,
when driving on uneven grounds, one of the two driving wheels may be lifted thus absorbing all oil capacity and idling. In this
condition the machine cannot move. To overcome this condition, press the differential locking button
ZG .
NOTE: To achieve maximum drive speed, set the speed selector (T) to position (III), press down the proportional joystick (A)
and hold down the differential locking button (ZG-OPTIONAL).
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 lifted platform, safety drive speed is automatically enabled, therefore neither speed selector
F nor differential locking button
L are active.
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.
