Yes but only a little bit. The adjustment may not be as necessary as you think.
1.Make sure you are level.
2.Make sure that your heights are even on the lift arms so it goes up straight (measure from the same point on the round lift arms to the same edge of the roof at all 4 lift arms, the forward 2 must match as well as the back 2.
3.If these are all ok AND all of the bolts are equally snug on the torsion units then tighten the big bolts only a little bit (maybe an eighth of a turn) on all 4 when up, test.
4 Repeat till happy, or too tired to do any more ups and downs with the roof.
