The brushes on my Dyson DC04 have jammed?

The brushes on my Dyson DC04 have jammed and are making the most horrendous noise. This is apparently the anti-jam brush mechanism to stop the belt breaking!

Does anyone know how I unscrew the cleaner to clean the brushes and remove whatever's blocking them?

done
there are 3 yellow plastic screws which are coin turn release, turn them 180 degrees and they will realease the soleplate
