With the boom unfolded (in the spraying position) while standing on
the rear side of the boom, check to ensure that the 7th pin connection
in the timing chain(on the 48' and 66' boom)(A)(Fig. 12) is aligned with
the center line between the sprocket cap screws (B)(Fig. 12).
To adjust timing, loosen the turnbuckles on the front and rear cables
until slack.
Line up the chain and sprocket as indicated in step 1.
