9. Retract the boom, checking that no excessive binding occurs.
10. Adjust the brackets on pads “1”, “3”, and “5” so the pads contact the base
boom section. Then “back off” until there is 1/32 inch max clearance between
the pad adjustment base and the pad. This must be done for the left and right
pad for each section. This will maintain a total clearance of 1/16 inch. Tighten
the lock bolts. This is done with the boom retracted.
11. A final check of boom alignment should be made by “stringing” as described
earlier and also by a visual inspection with the boom fully extended and at
maximum angle.
