Needing help from experienced coal miners (experienced Pinmen and Mechanics)

Long story short i need some of you guys to tell me how and where i can adjust my up pressure and my rotation on my double boom fletcher roof bolter. My mechanic wont do it. My up pressure and rotation is so bad it takes forever to drill a hole and i barely have enough up pressure to get my pins up. If your reply is going to be dont mess with it or ask your mechanic then just don’t reply im going to find away we got coal to run. Thanks in advance, and be safe down there ladies and gentlemen.
