The main drive chains are tensioned by adjusting the chain take-up units located at the
in-feed end of the machine (see photo below). To tighten the chains, loosen the jam nut
on the adjusting screw. Turn the adjusting nut clockwise to tighten the chains. Turn the
adjusting nut ½ turn on one side of the machine and then ½ turn on the other side of the
machine and check chain for tension. Proper tension is when the return tray carriers on
the bottom of the conveyor can be lifted up about 1
” without the chain feeling over tight.
If the chain is very sloppy when lifted, it is too loose. After adjusting, tighten the jam
nuts.
