Maintenance and Service
5.4.1 Charging batteries
Complete an initial battery
charge cycle to properly
ch
arge the batteries prior to
running the machine for the
first time. Hako assumes no li-
ability for damage to the bat-
tery caused by a fault when the
battery i
s charged for the first
time.
Ensure sufficient ventilation in
the chargi
ng area when charg-
ing the batteries – risk of explo-
sion.
Before charging the battery, wait until at
lea
st one charge status indicator bar
has extinguished after operating the
machine. The battery is charged by the
integrated on-board charger (Fig. 12/3):
1. Turn the machine off.
2. Remove the power plug (Fig. 12/4)
from its receptacle on the right-hand
side.
3. Plug the connector into a 230 V
main
s outlet.
Charging will start automatically.
The charge mode indicator (Fig. 12/2)
shows the progress. Pay attention to
the information in the operating manu-
als supplied with the charger and the
battery.
You cannot turn on the ma-
chine while charging. The ma-
chine will not be ready to oper-
ate until the power plug has
been
returned to its receptacle
(Fig. 12/5)
5.4.2 Charge status indicator
Check the indicator field (Fig. 12/1) for
th
e current charge status of the batter-
ies during operation. The charge status
indicator is connected to a total dis-
charge signal transducer (TSG) in the
machine control unit. Four segments on
the display are indicative of the batter-
ies being fully charged. The segments
extinguish one by one as more power is
drawn from the batteries. At the dis-
charge limit, the battery icon starts to
flash and the TSG turns off the cleaning
functions to prevent total battery dis-
charge (machines with a traction drive
can still be moved at reduced speed).
Charge the batteries immediately!
