My words!
There are different rollers available from Bosch to adjust the pre-lift, but the cam has to be out to change them. If your measurements and notes are not good you might do the cam disassembling more than 2 times...
Start of delivery is set by fixing the counterweights at a certain position on the cam (before that the pre lift adjustment has to be correct).
