The lithium-ion battery can be charged at any time without
reducing its service life. Interrupting the charging procedure
does not cause damage to the battery.
The "Electronic Cell Protection (ECP)" protects the lithium-
ion battery against deep discharging. When the battery is
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 (see figure G)
Note: Using unsuitable batteries can lead to malfunctions or
damage the machine.
Insert the charged battery (6). Ensure the battery is inserted
correctly.
To remove the battery (6) from the machine, press the bat-
tery unlocking button (5) 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
(6) is inserted onto the charger (10).
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 CV)
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.
Meaning of the Indication Elements
(AL 1830 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 .
F 016 L94 299 | (22.07.2021)
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".
Operation
Switching On and Off (see figure H)
To switch on, firstly press the lock-off button (3). Then
press the On/Off switch (4) and keep it pressed.
To switch off, release the On/Off switch (4).
Lawn Trimming/Edge Cutting (see figure I)
Turn the handle against the shaft by 180° to position the
trimmer head either for lawn trimming or edge cutting. Re-
lease button (2) so that the turning mechanism engages.
Now, turn the complete machine to the working position.
Lawn trimming
Move the trimmer left and right, keeping it well away from
the body. Cut higher grass in steps.
Edge cutting
Guide the trimmer along the edge of the lawn. Avoid contact
with solid surfaces or walls to prevent rapid wear of the cut-
ting line.
Cutting around trees and bushes
Carefully cut around trees and bushes so that they do not
come into contact with the cutting line. Plants can die if you
damage the bark.
