drinking alcohol or under the influence of intoxicating drugs or medication.
Inserting/removing the battery (see figure C)
Note: Using unsuitable batteries can lead to malfunctions or damage the machine.
Insert the charged battery (17). Make sure that the battery is fully fitted.
To remove the battery (17) from the machine, press the battery unlocking button (18) and pull the battery out.
Charging the Battery
Observe the correct 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.
The battery is equipped with temperature monitoring that allows charging only in the temperature range between 0
°C and 35 °C. In this manner, a high battery service life is achieved.
Note: The battery is supplied partially charged. To ensure full battery capacity, completely charge the battery in the
battery charger before using 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 cause damage to the battery.
The “Electronic Cell Protection (ECP)” protects the lithiumion 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 automatic shut-off of the product. The battery could
become damaged.
Observe the notes for disposal of the battery.
Charging Procedure
The charging procedure starts as soon as the mains plug of the charger is plugged into a socket outlet and the
battery (17) is inserted in to the charger
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.
Meaning of the Indication Elements (AL 1810 CV)
Flashing battery charge indicator The charging process is indicated by the flashing 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 indicator
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.
