I've printed the manual, it plainly describes how to adjust the blades to the cutting plate. I am sure I can follow the instructions easily enough.
It also answers another problem I had, I will explain;
Not too long ago I had the machine professionally sharpened by machine, just as your pic describes. It came back to me set right but after a short period the blades did not cut properly. I took it back and the guy re set it and the same thing happened again.
I took the chain cover off and found most nuts to be loose including the one that fixes the cutting adjustment, I tightened them.
It still lays some grass down and cuts the rest. I do a double cut to overcome the deficiency.
I will adjust the blades now that I know how, hopefully it doesn't need backlapping at this time.
I have changed the spark plug to a CJ8 equivalent.
