6.1.7.2 Potentiometer 1B1 and microswitches 1S21 - 1S22 of the accelerator
The accelerator is controlled by a radiometric value, a % of the supply voltage. This control mode always
helps to be at the important values for carrying out the acceleration and the regulation of the potentiometer.
The radiometric values are always true regardless of the variations in the supply voltage. They can be
displayed with the PathFinder application. The accelerator must be calibrated with the diagnostics
software.

6.1.7.3 Tiller rear safety control – 1S3
The anti-crash is available in the AP version. This safety works when the truck is in walkie configuration,
with raised platform and lowered guard rail. With the PathFinder software, you can also activate this safety
in stand-on configuration.
While moving, the action on the tiller rear safety control causes the following reaction:
- action on the tiller safety contact, the truck moves in the direction of the fork arms at reduced speed while
the tiller safety switch is not released.
- on releasing the tiller safety contact, if the accelerator is still activated , the truck moves with free wheel
until it stops.
Note 1: To retrieve the full drive, it is necessary to release the accelerator at zero and to
reaccelerate.
