Stihl Filling Mowing Heads AutoCut 25-2
The AutoCut mowing head has a line storage device and the line is fed while the machine is running. This is done by tapping the top of the mowing head on the ground. This opens the holding mechanism for the line and centrifugal force causes line to be fed out.
Open the mowing head by pressing sideways on the indentation cut-outs in the top casing. Then remove the base from the mowing head. First press one side inward until the catch disengages, then press the other side. Then remove the cover of the mowing head.
