OK
I am going to be MR Obvious here. Some of these posts are telling you to do this and do that. I could go through it step by step here in this forum....... But I won't
What you need is to find an experianced friend or go the the range and find someone who knows what they are doing to help you out.
This way they can get a look at your rig and point out the steps required so that you can remember in the future.
I have never drove a big rig truck and for my safety and the public's would not want to learn from a bunch of random posts on the internet.
Good Luck
