OPERATING INSTRUCTIONS (SW Version 2.3)
ACTIVATION OF THE GRAPHIC BAR FOR CONTROL SELECTION
Display of the load control system is equipped with a oang bar which shows control buons P1, P2, P3, P4 and P5.
The acvaon of this oang bar depends on the weighing mode selected by the operator:
1) In the ‘AUTO WEIGHING’ mode (see paragraph ‘WEIGHING SCREEN’), when one of the 5 selecon buons (P1, P2,
P3, P4 or P5) is pressed, the system acvates the graphic bar at the boom of display where the executable func-
ons are shown. The operator has 5 seconds to press the buon corresponding to the funcon to be executed. If
no selecon buon is pressed within 5 seconds, the system deacvates the graphic bar.
2) In the 'MAN WEIGHING' mode (see paragraph 'WEIGHING SCREEN'), when one of the 4 selecon buons (P1, P2,
P3 or P4) is pressed, the system acvates the graphic bar at the boom of display where the executable funcons
are shown. The operator has 5 seconds to press the buon corresponding to the funcon to be executed. If no
selecon buon is pressed within 5 seconds, the system deacvates the graphic bar.
If buon P5 is pressed in the manual mode, it does not acvate the graphic bar but it starts a weighing procedure for
the load being lied (see paragraph 'MANUAL WEIGHING' (E)

1) your machine should always be placed on a at, compact surface
2) your machine should be standing sll, with its wheels aligned with the chassis
3) the telescopic boom should be fully retracted and in a horizontal posion
4) the carriage should be in a vercal posion
5) the recommended weighing mode is the manual one (MANUAL WEIGHING)
In these condions the approximate tolerance of the load readout should be about ±5% of the maximum rated load.
The value of the load being lied is to be considered a mere indicaon for the operator. It has no scal signicance and
it is not a cered weight value.
The following part of this paragraph describes the various funcons of the weighing system.
