- Then raise them up 2-3 holes (more if you need to lower the front significantly to get the trailer level fore and aft).
Why raise up two or three holes? :h
I drop the manual legs and keep the spring loaded pins pulled out. Then lower the outer leg shaft electrically until one pin snaps in and seats in a hole. If the other pin has not seated (un-level site) I add a board or kick some dirt out until it does. The pins are almost always within 1/2 inch or less of a hole.
If you do not have spring loaded pins then I guess you would raise the manual leg shaft to the nearest hole and then lower electrically, but why 2-3? Just asking in case I am missing something here.
BTW: A tip to make getting the manual shaft back up easier. Always use a 2x6 board 2 ft or more long under the legs because it is easier to use the board like a lever to lift the manual shaft back up into the electric shaft. ;)
