How To Change The Mowing Head On An FSA 57 Grass Trimmer | STIHL GB

On some of the grass trimmers in the STIHL range, our FSA 57 for example, it’s possible to replace the AutoCut 3-2 mowing head with the PolyCut 3-2 mowing head, so that you can use polymer blades instead of nylon mowing line. ? First, make sure you’ve removed the battery or disconnected the power source. You need to remove the risk of the machine accidentally starting while you’re working on it. ? Prop the machine up so that you can access the mowing head. ? To remove the AutoCut mowing head, you need to grip the orange fan wheel at the top of the mowing head in one hand and then unscrew the head. ? Take the PolyCut mowing head and screw it on tightly. It’s that easy, you can switch between both heads at any point you wish! For more how-to videos, just take a look at the STIHL GB YouTube channel.
