Peter, my year 2000 handbook appears to be identical to yours. Perhaps this new shot will be of some help. I told a storey on this forum some time ago regarding the problems that I had assembling the rise/fall assembly. I struggled for quite some time to understand the instructions without success, fortunately my young granddaughter was watching me and said something like "granddad, do you think they mean.........."
with her nimble minded interpretation, the job was completed very quickly. When I sent in the warranty card I included a note saying something like "find a non-technical person with good writing skills and get him/her to assemble this unit from you current instructions and then get that person to re-write them!" Obviously they ignored my advice!
