Just got my 2424, and am excited to get busy. A question on Herculift assembly...the instructions are vague as to whether to tighten the bolts on the tubes that attach to the leg brackets. The instructions say to tighten them until the lock nut is flush with the bottom of the bolt, but never specifically state whether those should be tightened down. Instead, the instructions say to tighten all hardward on the upper and lower assemblies. Can anyone clarify? Thanks!
