- Insert adjusting rod (7) into the holes of front takeup shaft (6) in order to adjust the drag chain. If the drag chain in front of fifth drag bar (3) was touching supports (2), turn the adjusting rod counterclockwise in order to tighten the chain. If the fifth drag bar was not touching the supports, turn the adjusting rod clockwise in order to place more slack in the drag chain. Adjust the front takeup shaft in small increments.
- Check drag chain for the correct chain tension after each adjustment. Repeat Step 2 to Step 7 until the drag chain is adjusted correctly.
- Place the adjusting rod in the front takeup shaft. Place pins (5) in adjusting rod (7) .
