The Stihl FSA 90 is powered by the Stihl lithium PRO battery range & comes fitted with an EC brushless motor. Brushless motors work with greater efficiently than brushed versions & they run quietly with minimal vibration. Cordless power allows the user to work cable-free, emission-free & with minimal running costs. The lithium PRO batteries match the power of petrol engines, but without the noise & maintenance costs. Battery operated tools are very popular with groundsmen & contractors working in noise sensitive areas such as schools & hospitals. Stihl recommend the AP 300 battery (sold separately) which will run the FSA 90 for 45 minutes on a single charge. If you are a contractor working on larger areas purchasing a second battery is a productive way of working for longer periods. To increase battery life & ensure the tool stays disconnected until you need it, there is a two stage system to connect the battery; the 1st stage sit the battery in position so it can safely transported, the 2nd stage connects the battery ready for use. The FSA 90 bike handle design makes it absolutely ideal for working on large areas of dense vegetation & brambles. The robust 2-sided, 260mm grass cutting blade easily tackles overgrown areas of grassland & shrub. An Ecospeed setting means that you can select the cutting speed dependent on the working conditions, this multi-speed setting improves performance & run times. The brushcutter’s controls have been built into the bike handle making it extremely ergonomic to use. The FSA 90 comes with a double harness which will distribute the weight of the trimmer evenly across the shoulder & back. Comes with a hanging loop for storage. Battery & charger sold separately.
