The lithium-ion battery can be charged at any time without reducing its service life. Inter-
rupting the charging process does not damage the battery.
The lithium-ion battery is protected against deep discharge by the Electronic Cell Protec-
tion (ECP). When the battery is discharged, the power tool is switched off by means of a
protective circuit: The application tool stops moving.
Do not continue to press the On/Off switch after the power tool has automatic-
u
ally switched off. The battery can be damaged.
The battery features NTC temperature monitoring, which only permits charging in a tem-
perature range between 10 °C and 35 °C. This gives the battery a long service life.

– Open the flap (4).
– Connect the battery (5) to the power adaptor (9) using a USB cable (10).

progress.

If you are not planning to use the power tool again soon, disconnect the power adaptor
(9) from the mains.
