This is my first folding workbench ever. I did all of my previous projects on a fixed workbench in my basement. I consider myself as a handy person, but I had trouble assembling WM425 workbench because the assembly instructions did not mention at all the correct positioning of the jaws at the top of the workbench. The metal frame of the workbench has multiple cutouts which can accommodate the jaws, so I had to experiment with it to ensure that I can raise the front jaw. I am specifically complaining about steps 3 and 4 of the assembly instructions. A diagram showing the correct positioning of the jaws related to the metal frame would have helped, but it is missing now.
