With the trimmer head on the ground, on top of the gearbox where the head is, is a hole. You put a bar in and turn the head until the bar locates in a groove inside. This locks the shaft from moving so you can unscrew the head. I think it’s a left hand thread if I remember correctly.

With the trimmer head on the ground, on top of the gearbox where the head is, is a hole. You put a bar in and turn the head until the bar locates in a groove inside. Or even a screwdriver will do. This locks the shaft from moving so you can unscrew the head. I think it’s a left hand thread if I remember correctly.
