"Should an emergency situation arise during truck use, cut the power immediately by pulling out the mobile part of the **irreversible plug:** this will cut power feeding to the auxiliary and power circuits and the truck will be stopped because of the electromagnetic brake action."

"Once battery charge and the **irreversible pin connection** have been checked, insert the key in the switch (33) on the head control unit and turn it clockwise from position [A] to position [B] to power the unit."
