Maintenance and Service
5.4.1 Charging batteries
Complete an initial battery
charge cycle to properly
charge 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 is charged for the first
time.
Ensure sufficient ventilation in
the charging area when charg-
ing the batteries – risk of explo-
sion.
Before charging the battery, wait until at
least 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 230V
mains 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
the 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!
