Description of Operation
The power tool is operated with a
rechargeable battery. Use only STIHL
chargers to recharge the battery.
Data exchange
The power tool, battery and charger
communicate with each other. The
charger charges the battery and the
battery supplies the necessary power
only if data exchange functions properly.
For this reason you should operate your
power tool only with the approved STIHL
batteries and STIHL chargers.
