The STIHL FSA 80 R is a battery-powered brushcutter designed for tackling the toughest mowing, cutting and clearing jobs you may face in your home garden. The FSA 80 R is battery powered and as such has low noise emissions – so you don’t have to worry about disturbing any neighbours either!
Fitted with a new style loop handle that has a quick-mounting system, meaning you can adjust the handle to your height for an ergonomic working position. This handle also makes mowing on slopes, around trees or on uneven terrains even easier. The FSA 80 R has a powerful brushless EC motor and speed-adjustment on the control handle, which can be set at 2 different speed settings. There is an ECO mode (level 1), for simple tasks such as trimming lawn edges, which results in lower energy consumption for extended battery life. And there is full speed mode (level 2), for mowing thicker grass, which will use more of the battery energy.
The FSA 80 R is supplied with a basic harness and the AutoCut 27-2 as standard, but can also be fitted with other STIHL cutting tools, such as the TrimCut, DuroCut, PolyCut and GrassCut cutting tools.
Don’t forget to check your work area for wildlife before starting to use your tool. In particular, you should check for nesting birds before trimming hedges, as well as checking for other small animals such as hedgehogs before trimming long grass.
STIHL professional tip - to get the most from your mowing line, we recommend popping it in a bucket of water for 12-24 hours before using it to make it more flexible and less likely to break.
Hanging eyelet
FOR SAFE STORAGE. The tool has an integrated carrying ring. This allows you to store your tool safely and compactly.
Tool-free handle adjustment
SET THE BIKE HANDLE POSITION. You can individually adjust the ergonomic bike handle (mowing handle) using the central clamping device. Thanks to the tool-free handle adjustment, you do not need any tools for this. The bike handle can be rotated 90 degrees for transport and space-saving storage.
Tool monitoring with the Smart Connector
INTEGRATION INTO STIHL CONNECTED. The tool is compatible with the Smart Connector, meaning it can be integrated into the STIHL connected system. Once you have attached a Smart Connector to the tool, after one-time commissioning it will record the tool’s operating hours and transmit them to the STIHL connected App via Bluetooth. In addition to displaying the operational time, the app also provides an overview of all necessary maintenance, ensuring that you do not overlook important upkeep and that your tool is always in a ready-to-use condition.
EC motor
LOW-MAINTENANCE AND EFFICIENT. Thanks to its compact design, low weight and high efficiency, the EC motor enables you to work in an energy efficient manner. This engine also has a long service life.
Power levels
PERFORMANCE SUITABLE FOR THE TASK. You can change the power of your device thanks to 2 different power levels. At level 1, you reduce the power (Eco mode) and extend the battery life. Level 2 allows you to call up full power. This means that you can either work particularly energy-efficiently or use all the power of the device when you need it.
Constant power
CONSTANT POWER, REGARDLESS OF BATTERY CHARGE STATUS. With other brands of battery tools, the performance usually decreases during work as the battery discharges. This is not the case with STIHL cordless power tools with CONSTANT POWER. Thanks to the intelligent electronics, your STIHL power tool works with consistently high power.
