Semi-discharged battery warning light (yellow)7c. Discharged battery warning light (red)Hour counter and solution level display:When the machine is started, it displays for a fewseconds the number of working hours which have beenperformed.While using the machine, it displays the solution levelin the tank (measured in percentage terms, comparedwith the full tank). When the level is below 20%, thedisplay starts blinking. The display could indicate“000 %” even if the tank is not completely empty, thusallowing to complete the cleaning cycle; in any case,it is recommended to check the actual solution flowsupplied to the brushes.Solution flow control switches10a.
