First Camping Incident - one lesson learned

Aua Aua my daughter would say, and its true, it really did hurt when I wanted to try the new camping gas cooker. I learned a very good lesson, when I wanted to force down this little closing mechanism. "Do not force things, either it goes smoothly or something must be wrong"

Yes, there was something wrong, I didn't had the regulator on 0, therefore that locking mechanism wouldn't allow me to engage the can of gas. When I saw it, and fixed it on 0 all went down as it should.
The little scratch there is already healing fine, so dont Worry, be happy !
