This is how i set an fd70.
--Lock wings into rigid position. Raise and lower header to ensure they both lock in properly.
--Raise header 6" off ground
--Tilt header to B-1/2
--Put reel f/a to 5ish or about half way out
--measure and make sure the bolt length on the pair of springs are the same length
--Loosen locknuts and tighten springs evenly (count turns) (clockwise)until header just lifts on its own (washer will be loose under big nut on lockout bolt) i sometimes will lift header a little by hand and see if it settles or floats a little. When washer stays loose, loosen both spring bolts 2 turns each.(counterclockwise)
--repeat spring tightening procedure on other side.
Note: ive never tried an impact wrench on spring bolts, but would bet it wouldnt work because of the spring, springing. Use a wrench, or breaker bar.
After float is set, unlock wings to flex mode, remove plastic covers and set wing balance, use your wrench and try so set so you can smile and frown it with about the same force.
I usually run it for a bit and watch my wing indicators in the field, if one always tends to smile or frown, ill adjust a bit, usually doesnt take much adjustment to make a difference.
Hope this helps
