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 and release “dead-man” button
ZD
located on the platform; the green led
O
will light up steady indicating its enabling.
b)
Within 5 seconds from the green steady led
O
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 other platform
movement controls (lifting/lowering/extension/retraction/levelling outriggers).
Drive control is active only if drive enable green warning light (R) is ON. If it is OFF, drive control is
disabled. See paragraph “Warning lights”.
With platform completely lowered, operating the drive speed selector
F , and/or differential lock button L , different drive speeds can
be selected. Due to the rigid frame 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 lock button
L .
NOTE: To achieve
maximum drive speed
, set speed selector
F
to position
III
, hold down the differential lock button
L
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
F
to position
I.
To operate on high descending slopes
(e.g. while unloading the machine from a truck) set the speed selector
F
to position
I.
With lifted platform, safety drive speed is automatically enabled, therefore neither speed selector
F
nor differential locking button
L
are active.
WARNING!! The differential lock button (L) is to be used by the operator to drive the machine on uneven grounds, if one
of the driving wheels is lifted and absorbs the whole drive power and to perform rapid straightforward movements. Do not
hold down this press-button while steering.
To steer, press buttons
A1
or
A2
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 or dead-man button and is possible only if:
enabled control station green warning led O is ON;
drive enable green warning led R is ON.
