Great tips. However, beware that screw for adjusting the locking system. The threading in that hole can easily break. At least it appears to what has happened with mine. Once that happened, the locking mechanism will freely rotate and the screw wont be able to hold it in position anymore. I was only able to fix it by replacing the tiny screw and with a bigger one. Badly constructed in my view. Not good for a system that is supposed to ensure safety...
