Operation
Charge mode indicator (Fig. 10/2)
Four green LEDs indicate the charge
mode with reference to the current
charging stage. If the battery is dis-
charged, the two bottom LEDs light up.
While charging, the other LEDs light up
one by one.
The number of LEDs lit up corresponds
to the following charge status:
1 LED:
Soft start, battery pre-charge cycle
2 LEDs:
Main charge - battery is being charged
3 LEDs:
Trickle charge - charge level 80%
4 LEDs:
Charge cycle complete - charge level
100%. Charge retention is enabled.
Flashing of the bottommost
LED is indicative of a fault. See
charger manual.
Hako chargers are designed to
work continuously, i.e., at the
end of the charge cycle, the
charger automatically enables
charge retention to ensure that
the battery is always perfectly
charged. To get the most from
your battery and optimize its
service life, it is best to always
fully charge the battery (four
LEDs on).
Main switch (Fig. 10/3)
The main switch is used to switch the
electrical system on and off. The indica-
tor field displays the software version
and last service code briefly after
switching on.
Remove the key to prevent un-
authorized use of the machine.
Bail system switch (Fig. 10/4)
Letting go of the bail system switch dur-
ing operation stops the traction drive,
the brush head drive and the solution
supply. The suction turbine remains
switched on.
