The STIHL HSA 100 battery hedge trimmer offers effective support in horticulture and landscaping, as well as public authorities, for trimming and pruning large hedges efficiently and conveniently in noise-sensitive areas. The STIHL HSA 100 is a very high-performance hedge trimmer with a maintenance-free EC engine. The engine is powered by lithium-ion batteries from the STIHL AP-System. It always delivers a constant stroke rate even under load, and even when cutting thicker branches. The double-sided cutting blade delivers precise cuts, both when trimming and pruning. If tough branches block the blade system, you can quickly get going again simply by changing the rotation direction.
