Notified body: SRL, Sudbury England, Nr. 1088
f Observe the mains voltage! The voltage of
the power supply must correspond with the
data given on the nameplate of the battery
charger. Battery chargers marked with 230 V
can also be operated with 220 V.
Technical file at:
Bosch Lawn and Garden Ltd., PT-LG/EAE,
Stowmarket, Suffolk IP14 1EY, England
Use only the charging unit supplied. Only this
charging unit is matched to the lithium-ion battery used in the product.
Equipment category: 33
Bosch Power Tools
F 016 L70 777 | (27.10.10)
12 | English
The battery is equipped with temperature monitoring that allows charging only in the temperature range between 0 °C and 45 °C. In this manner, a high battery service life is achieved.
Note: The battery is supplied partially charged.
To ensure full capacity of the battery, completely charge the battery in the battery charger before using your power tool for the first time.
The lithium ion battery can be charged at any
time without reducing its service life. Interrupting the charging procedure does not damage the
Continuous Lighting of the Battery Charge Indicator 13
Continuous lighting of the
battery charge indicator 13
indicates that the battery is
fully charged or that the temperature of the battery is not within the allowable charging temperature range, and cannot be
charged for this reason. The battery is charged
as soon as the allowable charging temperature
range is reached.
Press the battery unlocking button and pull out
the battery 15 toward the rear.
When the battery is not inserted, continuous
lighting of the battery charge indicator 13 indicates that the mains plug is inserted in the socket and that the battery charger is ready for operation.
Charging Procedure (see figure A)
Charging Advice
The charging procedure starts as soon as the
mains plug is plugged into the socket and the
battery is then inserted into the battery charger
With continuous or several repetitive charging
cycles without interruption, the charger can
warm up. This is not meaningful and does not indicate a technical defect of the battery charger.
Firstly, place the battery 15 as shown in the figure onto the front of the battery charger (n) and
then press the battery 15 down at the rear (o).
To remove the battery, proceed in reverse order.
A significantly reduced working period after
charging indicates that the battery is used and
must be replaced.
Removing the Battery (see figure A)
Due to the intelligent charging method, the
charging condition of the battery is automatically detected and the battery is charged with the
optimum charging current, depending on battery temperature and voltage.
This gives longer life to the battery and always
leaves it fully charged when kept in the charger
for storage.
Note: The charging procedure is only possible
when the battery temperature is within the allowable charging temperature range, see section “Technical Data”.
Flashing Battery Charge Indicator 13
The charging procedure is signalled by a flashing battery
charge indicator 13.
The “Electronic Cell Protection (ECP)” protects
the lithium ion battery against deep discharging.
When the battery is run down or discharged, the
garden product is shut off by means of a protective circuit: The blade no longer moves.
Do not continue to press the
On/Off switch after the garden
product has been automatically switched off.
The battery can be damaged.
