A. For Regular Tightening:

IMPORTANT AT ALL TIMES OF OPERATION! Correct apron tension occurs when the return main apron slats ride 2" at mid span off of the front pair of wooden slide rails and only one apron slat touches at mid span on the rear pair of wooden slide rails.

For Additional Regular Tightening Adjustment: Move the main apron tightening pivot arm, pivot bolt down the length of the shackle bracket closer to the an- choring bolt.

NOTE: After repeated regular tightening of the main apron chain assemblies and when the return main apron slats begin to “bottom-out” onto the top of the 10” chan- nel iron of the steel frame stringers, remove equal num- ber of links from each apron chain assembly. Reset anchoring eye bolts for correct main apron tension.

B.For Fine Tightening & to Equalize Stretch in Indi- vidual Chain Strand Pairs.

1.Allows to Fine Adjust/Tighten Individual Chain Strand Pairs of each Main Apron.

2.Allows to Equalize Stretch in Individual Chain Strand Pairs of each Main Apron.

Loosen the anchoring eye bolt on the main apron chain prior to making the adjustments on the individual chain strands. This will allow easier adjustment of the adjuster bolt. Located on the inner chain strand of each main apron assembly, there is an adjustable, tightening pivot arm with a ½” x 1-1/4” adjuster bolt. Turn this ½” X 1-1/4” bolt by first loosening two set screws located on the ad- justable pivot arm. Tighten or loosen the ½” adjuster bolt to make fine adjustment/tightening in the individual chain strands or to equalize stretch in the individual chain strand pairs of each independent main apron as- sembly. Retighten the two set screws and retighten the anchoring eye bolt for correct apron tension.
