the suction motor.
Low voltage detected on function board (<90%). Check batteries and
batteries connections.
Low voltage detected on function board (<80%). Check batteries and
batteries connections.

connections.
Overvoltage detected on function board. Check batteries and batte-
ries connections.
check brush motor/traction motor absorption
check brush motor/traction motor absorption
To empty recovery tank
Reboot scrubber drier (do not press user lever before control board
check)
Reboot scrubber drier
Check connections between the function board and dashboard.
Check connections and traction motor status.
