FSA 90 R
Professional straight-shaft trimmer powered by a 36-volt Lithium-ion battery for excellent cutting performance. Battery & charger sold separately.
The FSA 90 R trimmer combines the benefits of Lithium-ion technology with the renowned power of STIHL. A quiet, battery-powered trimmer, the FSA 90 R is great for landscaping in noise-sensitive areas like school grounds, business districts or hospitals. If it’s ease of use you’re looking for, this is the trimmer you need – it’s lightweight, has a 15” cutting width, ergonomic loop handle, a slim profile for easy handling and transport, and starts instantly with a squeeze of the trigger. Additional benefits include the innovative control handle with ECOSPEED “soft” stop trigger setting, which can extend the amount of work done on a single charge. The time for trimming fuel costs and exhaust emissions is now, and the FSA 90 R is the right tool for the job.
Batteries and chargers must be purchased separately. Run time on a single battery charge can vary and depends on the battery type, charge level, tool model, operating conditions, and the user's operating style.
