empty, the product is switched off by means of a protective
circuit: The product no longer operates.
Do not continue to press the On/Off switch after an auto-
matic shut-off of the product. The battery could become
damaged.
Observe the notes for disposal of the battery.
Inserting/Removing the Battery
Note: Using unsuitable batteries can lead to malfunctions or
damage the machine.
Insert the charged battery. Ensure the battery is inserted
correctly.
To remove the battery from the machine, press the battery
unlocking button and pull the battery out.
Charging Procedure
The charging procedure starts as soon as the mains plug of
the charger is plugged into a socket outlet and the battery is
inserted onto the charger .
Due to the intelligent charging method, the charging condi-
tion 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.
Meaning of the Indication Elements (AL 1810)
Flashing battery charge indicator
The charging process is indicated by the flash-
ing of the battery charge indicator .
Solid light on battery charge indicator
A solid light on the battery charge indicator
signals that the battery is fully charged or that
the temperature of the battery is not within the
permitted charging temperature range, and
can therefore not be charged. The battery is charged as soon
as the allowable charging temperature range is reached.
When the battery is not inserted, a solid light on the battery
charge indicator signals that the mains plug is inserted in the
plug socket and that the charger is ready for operation.
Understanding the Indicators (AL 1815 CV)
Flashing battery charge indicator
The charging process is indicated by the flash-
ing of the battery charge indicator .
Continuous lighting of the battery charge indicator
Continuous lighting of the battery charge in-
Full
dicator 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.
Bosch Power Tools
When the battery is not inserted, continuous lighting of the
battery charge indicator indicates that the mains plug is in-
serted in the socket outlet and that the battery charger is
ready for operation.
Meaning of the Indication Elements
(AL 1830 CV / AL 1880 CV)
(Fast) Flashing of the Green Battery Charge Indicator
The rapid-charging procedure is indicated by
fast flashing of the green battery charge in-
dicator .
Note: The rapid-charging procedure is only possible when
the battery temperature is within the allowable charging
temperature range, see section "Technical Data".
(Slow) Flashing of the Green Battery Charge Indicator
When the charging condition of the battery is
80%, the green battery charge indicator
flashes slowly.
The battery can be removed for immediate use.
Continuous Lighting of the Green Battery Charge
Indicator
Continuous lighting of the green battery
Full
charge indicator indicates that the battery is
fully charged.
When the battery is not inserted, continuous lighting of the
battery charge indicator indicates that the mains plug is in-
serted in the socket outlet and that the battery charger is
ready for operation.
Continuous Lighting of the Red Battery Charge Indicator
Continuous lighting of the red battery charge
indicator indicates that the temperature of the
battery is not within the allowable charging temperature
range, see section "Technical Data". As soon as the allowable
charging temperature range is reached, the battery charger
automatically switches to rapid charging.
Flashing Red Battery Charge Indicator
A flashing red battery charge indicator indic-
ates a different malfunction of the charging
procedure, see section "Troubleshooting – Causes and Cor-
rective Measures".
Working Advice
Cutting Capacity (Battery Operating Duration)
The cutting capacity (battery operating duration) depends
on lawn properties, such as grass density, moisture content,
grass length and height of cut.
Switching the machine on and off frequently during cutting
will also reduce the cutting capacity (battery operating dura-
tion).
To improve the cutting capacity (battery operating dura-
tion), it is recommended to cut more frequently, increase
the cutting height and walk at an appropriate pace.
