Operation
Charge mode indicator (Fig. 9/2)
Four green LEDs indicate the charge
mode with reference to the current
charging stage. If the battery is
discharged, 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 cycle - battery is being
charged
3 LEDs
Trickle charge - charge level 80%
4 LEDs
Charge cycle complete - charge level
100%. Charge retention is enabled
26
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. 9/3)
The main switch is used to switch the
electrical system on and off.
Bail system switch (Fig. 9/4)
Letting go of the bail system switch du-
ring operation stops the brush head dri-
ve and the solution supply. The suction
turbine remains switched on.
Pulling up the bail system switch enab-
les the brush head drive's power flow
effect to support the machine drive.
