a) Check the distance between the apron chain and the bottom of the side sheet at the apron's
lowest point Gust behind the wheels). If the distance is more than six ( 6) inches, the chain
must be tightened.
NOTE:
The recommended floor apron chain tension is achieved when the apron's lowest
point is 4 to 4-1/2inches below the frame (behind the tire).
b) Use a9/16" wrench to loosen the two side nuts on each side of the spreader box as shown
inFigure4A. Then, turn the
front
nut clockwise with a 9/16" wrench until proper tension is
achieved. Repeat for the other side.
Make su
r
e that the chains on each side of the
apron are equally taut.
c) When the apron chain adjustment is accomplished, re-tighten the side nuts.
•
Apply chain lube once a month to the floor apron chain; use vegetable oil or a common spray lube
for chains.
