Hi, I have just bought a 2nd hand Dewalt recpricating saw (DC380). It came without blades so purchased these blades which say they are copatible with Dewalt:

It works and the blade is locked and won't come out however there is some vertical movement of the blade when fitted. Video here:

Is this normal? Is there something to tighten on the tool?
