Put it through it's whole range of motion and check all the fittings. I recently had a BH 92 mounted to my MX, and as I was loading it on the trailer at the dealer, I thought I had better do that. Well, one of the mounting brackets was about 1/16" off and snapped of a hydraulic fitting on the boom. THANKFULLY it happened in their parking lot. Took about 30 mi to fix, but again, glad I found out at the dealer. Had to put a new fitting on and grind away some of the mounting bracket.
