If I use my router in the table it works perfectly. The problem I have is when I use it as a portable. Once I set the depth and tighten it down making sure it is secure and start working, if I don't keep at least my thumb on the depth adjustment ring it wants to migrate down as I am cutting. Is there something I'm doing wrong or is it a faulty router. The manual say nothing about this problem and a couple of my friends have never heard of this either, but I'm sure one of you guys might have a suggestion. Thanks for the help.
