Not familiar with that model,has it got a Mitsubishi TL43 engine and the strimmer is a different make ?Do you want to unscrew the whole head off or split it apart to to put in new lengths of nylon, its the latter that is normally done to change the "strand"
any chance of a picture of the head as there are several types?
