You remove the strimmer holder by clamping underneath it. It might be possible to hold the strommer housing and unscrew it - normal right hand thread. If not, use a pair of mole grips above the holder (it is facing upwards in the vice). Clean out the bearing and grease. Reassemble in reverse order. It is worth noting that the cutter has to be fitted the right way round so make a note before dismantling the directions of the strimmer. It is possible that there is too much space to clamp the cutter so a packing washer/s could be required.
