Hi, I've just joined this forum looking for information on an old Manitou forklift. Plate on the side says MC55H and I think its around 1968-1972 ish. I notice you are also in France and was wondering if you found any help for manuals or parts etc. My steering hydraulic block at the steering wheel has blown the seals and the shaft is worn. I can't find any information which surprises me as Manitou is a French company but seems to have no internet presence for old machines.
Cheers
