I have found 2 designs. the older one will comea apert
almost completely,
the levers are held on by circlips. The later one has thigns riveted in
place. With the fomer, take it apart and clean all the bits with
propan-2-ol. With the later, unhook the springs, saak the parts
(particularly the right hand side plate) in propan-2-ol, work the levers
back and forth and wipe off the grease as it emerges.
Tony,
Mine has circlips. I have taken these off and refitted them before
elsewhere, but here I am having a devil of a job to put them back. Is there
a trick to this?
Regards
Rob
