back the adjuster bolt out to allow the adjuster to move
up and down freely. Figure 6-5

tight. Then tighten just enough to carry the weight of the
front of the deck on that side—to check, move the blocks
back and forth; they should move with a slight drag.

and jam them tightly together against the block.
28. Compress the deck lift assist springs so that there is 1/2”
(12.7mm) of space between the front nut on the spring
