WARNING!
Overvoltage damages batteries and the battery charger.
v
Ensure the correct mains voltage.
Before using for the first time, the battery must be fully charged.
Charging time (for uncharged battery) see 10. Technical Data.
The lithium-ion battery can be charged in any state of charge,
and the charging process can be interrupted at any time without
harming the battery (no memory effect).
1. Depress both locking buttons
4
and remove the battery
5
from
the battery holder
6
on the handle.
2. Plug the plug of the charger cable
7
into the battery
5
.
3. Plug battery charger
8
into a mains socket.
Charging indicator lamp
9
at the charger unit flashes green
once per second: Battery is being charged.
Charging indicator lamp
9
at the charger unit is lit green:
Battery is fully charged.
(For charging time, see 10. Technical Data.)
Battery charging status indicator during charging:
100 % charged L1, L2 and L3 lit.
66 – 99 % charged L1 and L2 lit, L3 flashing.
33 – 65 % charged L1 lit, L2 flashing.
0 – 32 % charged L1 flashing.
4. First remove the charging cable
7
from the charging socket
5
and then unplug the battery charger
8
from the mains socket.
5. Slide battery
5
onto the battery holder
6
on the handle until it
audibly engages.
Avoid exhaustive discharge:
If the battery is empty, the full discharge protection automatically
switches off the device to prevent the battery from discharging
fully. To prevent the fully charged battery from self-discharging
via the unplugged charger, it should be disconnected from the
charger after charging. If the battery was stored for more than
1 year, it must be fully recharged. If the battery was fully dischar-
ged, the charging indicator lamp
9
will flash rapidly at the start
of charging (twice per second). If the charging indicator lamp
9
still flashes rapidly after 10 minutes, a fault has occurred (see
8. Troubleshooting). If the error-LED
ß
W
on the battery flashes,
a fault has occurred (see 8. Troubleshooting). In case of a com-
pletely empty battery it will take approx. 20 minutes until the
LEDs on the battery will indicate charging. But the charging
process is indicated by the flashing LED
9
on the charger.
