A. For Regular Tightening:
IMPORTANT AT ALL TIMES OF OPERATION!
Correct apron tension occurs when the return main
apron slats ride 2"at midspan offof the front pair of slide
rails and only one apron slat touches at mid span on the
rear pair of slide rails.
For Additional Regular Tightening Adjustment:
There are 3 anchor holes on the clevis end of the
tensioner rod. Relieve tension and anchor the clevis to a
different hole when there is no more adjustment.
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 channel
iron of the steel frame stringers, remove equal number of
links from each apron chain assembly. Readjust the
spring loaded tensioner for correct
main apron tension.

chain prior to making the adjustments on the individual

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 adjustable pivot arm. Tighten or loosen the ½” ad-
juster bolt to make fine adjustment/tightening in the indi-
vidual chain strands or to equalize stretch in the
individual chain strand pairs of each independent main
apron assembly. Retighten thetwo set screws and read-
