Operation
Operating hours 
counter
(Fig. 17/5) The four-digit
LED serves to display
the operating hours.
When the key in the key switch is turned
on, one and then two four-digit codes
appear in succession (for further de-
tails, refer to Page 36, Key Switch
(Fig. 18/1)). The operating hours ap-
pear after this.
The counter only operates when con-
sumers are switched on (e.g. hydraulic
or brush motor, suction turbine). At the
same time, a red dot flashes at the bot-
tom right of the display.
Service indicator
(Fig. 17/5) 
The same LED also
serves for a more accu-
rate determination of
function faults. If a fault occurs during
operation, a four-digit code (error code)
appears in the service indicator display.
At the same time, the four dots of the er-
ror code flash in the display and a pul-
sating acoustic signal is issued. The
control lamp in the functional fault dis-
play lights up red. Section 3.5 provides
an overview of the error codes which
help you clear functional faults yourself.
Clear the fault before starting to use the
vehicle again. If you cannot clear the
fault yourself, note down the error code
and inform the authorized Hako dealer
responsible for your vehicle.
Battery and charge
control indicator
(Fig. 17/6) After switch-
ing on the key switch, all
four lamps light up when
the battery is fully
charged. As the battery is discharged
during operation, the three right-hand
lamps indicate the level of discharge by
going out in sequence from right to left.
When the left, red lamp flashes, it indi-
cates that work must come to an end.
Approximately three minutes later, the
brushes will return to their home posi-
tion. After a further three minutes, the
suction turbines are deactivated and
the squeegee is raised. When the red
lamp lights up continuously, approxi-
mately one minute remains until the en-
tire vehicle shuts down automatically.
Drive back to the charger in
good time. Take the distance
to the charger into account.
