Gathering Chain Tension

Prior to seasonal operation inspect the tension on the
gathering chains (A).

Inspecting:

1) Pull the gathering chain (A) outwards, at the
location of the red arrow, until the tensioning
fork (B) bottoms out.
2) Mark the tensioning fork (B) where it enters
the gathering chain guide (C).
3) Release the gathering chain and measure the
distance between the mark made in Step 2 and
the gathering chain guide (C).
a. Distance between the mark and the
gathering chain guide should be 1/4"
to 5/16” (6mm to 8mm).

Adjusting:

1) Loosen the jamb nut (D).
2) Tighten or loosen the tensioning bolt (E).

tighten the jamb nut (D).
