As an entry-level model, the STIHL FSA 45 cordless brushcutter is ideal for trimming and clearing work in your home garden and outdoor domestic spaces. The lawn trimmer has a permanently integrated lithium-ion battery, the charge level of which can be read directly on the device by means of several LEDs. You can charge the battery when required using the cable supplied. The electric motor operates so quietly that you do not need to wear hearing protection during use, making this brushcutter ideal for use in noise-sensitive areas.

Weighing just 2.3 kg, the battery-powered STIHL FSA 45 brushcutter is particularly light and very comfortable to use. The telescopic shaft and loop handle can be adjusted without using tools, so you can protect your back as you work. The mowing unit’s working angle can be easily adjusted if you want to cut vertical edges, for example. Thanks to the fold-out spacer bracket, you can trim around trees and plants as well as other objects smoothly and precisely. The soft-grip handle sits comfortably in the hand and, thanks to the control lever and control lever lock, allows you to control the cordless lawn trimmer reliably and safely at all times. The brushcutter also comes with a hanging eyelet for compact storage.

The STIHL FSA 45 brushcutter is equipped with an activation key which must be inserted into the key socket for operation. For safety reasons, this key must be removed during transport, maintenance, repair and storage. Please keep the activation key out of the reach of children. Further information can be found in the user manual.
