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 R has a soft-grip loop handle which is ideal for working in areas where there are a lot of obstacles & trees & also narrow spaces. Stihl’s Autocut 25-2 trimmer head has a durable 2.4mm nylon line & the head can be attached without the need to remove the casing. Auto Cut heads release extra line by tapping the head on the ground. The FSA 90 R is supplied with a basic harness & a hanging loop for storage. Battery & charger sold separately.
