The FSA 57 battery-powered grass trimmer is the ideal tool for keeping your lawn edges in check in medium to large gardens.
It is lightweight, quiet and easy to manoeuvre around your garden, with an adjustable loop handle that helps you to guide the trimmer exactly where you need it. The shaft is also extendable, so you can adjust it to suit your height.
The FSA 57 is part of our AK System of tools with interchangeable batteries - the battery in the FSA 57 can be used in other tools in this range including a hedge trimmer, blower and lawn mowers.
- Run time on recommended AK 10 battery: Up to 25 minutes
- Run time on AK 20 battery: Up to 50 minutes
- Run time on AK 30 battery: Up to 60 minutes
The STIHL AK Cordless System tools are so quiet you don't even need to wear ear protection.
Adjustable length shaft
The length of the shaft on the FSA 57 can be easily adjusted at the touch of a button to suit you whatever your height.
Adjustable loop handle
So that you can work in the most comfortable position for you, the loop handle can be easily adjusted without tools.
The metal spacer bracket means you can trim precisely around trees, plants and other objects without damaging them. It can also be folded up if not needed.
Safe battery locking position
There are two positions for the battery - in the first neutral position, the battery is secured in the grass trimmer but is not connected to the contacts, so you can carry the battery around easily without the risk of the trimmer starting accidentally. Once you push the battery in fully, you can easily start the tool.
Charge level indicator on the battery
So you know how much charge you have left, the charge level can be viewed at any time using the four LEDs on the battery.
Easy to extend the mowing line
The FSA 57 uses the Autocut C3-2 which you can tap on the ground to automatically feed out the mowing line if it has broken off. You can also fit the PolyCut 3-2 head to the FSA 57, which uses blades instead of mowing line.
AL 101 charger
Charger for the STIHL AK Cordless System. With operating mode indicator (LED) and cable tie with Velcro tape. The charger can be wall mounted if required.
FAQsQIs this grass trimmer suitable for trimming through weeds or scrub?
A: No, the AutoCut mowing head on the FSA 57 is only suitable for trimming grass, along lawn edges or in small areas of lawn. If you need to cut thicker, woody material, a brushcutter with a grass cutting blade or brush knife may be more suitable. You can find out more information about the different cutting attachments we have available on the STIHL Blog. Please visit your nearest STIHL dealer, who will be able to give you expert advice and talk you through our full range of brushcutters and cutting tools.QWhat type of cutting attachment does this use?
QHow long does the battery last?
A: The AK 10 battery will last up to 25 minutes or mow up to 500m of lawn edges, depending on the type of grass that is being cut and how the tool is being used.
QHow long does it take to charge?
A: To fully charge the battery it takes 80 minutes, or to charge it up to 80%, it takes 55 minutes.
QWhat size garden will it maintain?

QWhat battery does it use?

QAre the batteries interchangeable?
A: Yes, all of the tools in the AK Cordless System use the same style of battery. There are three different batteries in the range, which all have different capacities.
