ASSEMBLY
Preparing the Adapter (cont’d.)
INSTALL FEED DRAPER
1. Pull front of plastic panel up and back, well away
from idler roller and tightener mechanism.
2. Loosen nut (G), both sides, and pull up on idler roller
to rotate to position (A). Nut (G) must be loose
enough that idler arm easily passes by adjusting rod
(J).
NOTE: Rod (J) may come out of position when lifting
idler roller. It will return to proper position when roller
is moved to working position (B). Try moving idler
roller from position (A) back to working position (B). If
roller does not pivot over, loosen nut (G) further.
When nut (G) is properly loosened, pull roller up to
position (A) for installation of draper.
3. Install feed draper on adapter rollers, ensuring belt
on underside seats properly on left side of both
rollers.
4. Pre-install screws (F) in connector slat. Screws fit
tightly into slat holes. To install, support slat on both
sides of hole and hammer screw into hole. Position
connector slats (D) as shown below with heads
leading in direction of travel.
5. Apply draper tension as follows:
a. With nut (G) loosened per step 2, swing roller from
position (A) to working position (B), standing on
ends of roller if necessary. Take care not to
damage roller or draper seal.
b. Back off nut (H) and adjust position of nut (C) to
align bracket with welded channel as shown. This
position provides proper spring tension. Tighten nut
(H) against nut (C) to secure the position. Repeat at
other side.
c. Tighten nut (G), both sides, ensuring that formed
end of adjusting rod seats properly in pocket
formed into idler arm and that rod is positioned at
bottom of cut-out in side of pan.
6. Attach front end of plastic panels to front of feed
deck with four screws provided (two per side,
heads on top).
IMPORTANT: Panel hardware should not be over
tightened. Tighten locknuts to close gap between
plastic panel and feed deck flange, yet still allow
screw to move in flange slot.
