I possess one of these but recently had a mishap with the blade rotation
lever which has snapped at the base. I have had the lever repaired but
cannot seem to be able to connect it correctly. The spring is the
problem and the instruction book and diagram showing the offending item
is not clear. Has anyone had experience of dealing with this? It is
apparent to me that the spring must be " coiled" slightly to provide
resistance but how it fits is not known to me as the parts were
separated when the lever failed.
