Equipment and function of the AS system
Constant power, irrespective of battery charge status
With other brands of battery tools, the performance usually decreases during work as the battery discharges. This is not the case with STIHL battery power tools equipped with the Constant Power feature. Thanks to the intelligent electronics, your STIHL power tool operates with consistently high power.
Splash water deflector
The IPX protection classes define the moisture protection of electrical or electronic devices. The moisture protection test is defined in different stages. IPX4 tests the protection against splash water from all sides. This means that the battery power tools of the AS system with this certification are designed for daily use even in rainy conditions.
