5.1 Low battery indication iForks
Exchangeable batterypacks supply power to the iForks .
When the voltage level of the batterypacks is running low, the low bat indicator will light up and the
pointer of the relating fork - “F1”, ”F2” or both - will start blinking in the display.
The blue LED’s on the relating fork will start blinking very slowly (twice every 10 sec). The iForks will
switch off automatically after 10 minutes.

5.2.5 Charge the rechargeable batterypacks (option)
The system additionally can be equipped with rechargeable batterypacks and a charger.
Charge the battery for at least 8 hours. This will prevent loss of battery capacity. First read the label on
the batterypack to check if the batterypack is rechargeable!
First position the batterypack inside the charger module, then plug the adaptors into the mains voltage.
When the battery is being charged, the red LED on the charger is lit. After at least 8 hours charging,
the batterypacks are full again. The red LED will stay on, even when the batterypacks are fully
charged.

As standard, the indicator is equipped with 4 AA batteries. As an option the power supply can be
sourced via the truck’s main battery. This must be ordered separately, since the indicator needs to be

Before each weighing: check the zero point!
Before each weighing it is necessary to check
whether the system is unloaded and free.
If the indicator does not determine the zero point
automatically, it must be done manually using the
>0< key.
Before the next weighing,
check the zero point again.
