This is not a pilot technique issue, it’s bad maintenance pure and simple, at one time the MM advice was poor and lost a lot in the translation from French to English but Robin have cleared up their act and the MM gives very clear advice on landing gear maintenance.
Setting up correct oil level is nothing like the way the Americans do it and if the American technique is used it results in a much less aggressive spring rate rise and so a very soft main gear , the result of this is a nose high attitude on the ground and the nose centering lock remaining engaged far too long preventing the rudders from actuating the nose gear steering.
