lambs,

When you changed the blades did you take off the blade plate?

If you did then the bet is that you have not put the blade plate washer back on correctly or did not tighten the nut properly. It has stamped on it nut side on one side and that should be facing the nut.

If the plate is loose you will see the metal underneath the washer starting to get shiny.

Let me know what you find before we further. cheers2
