NOTE: When using double eliminator, set vacuum to approx. level 15 and install double notch brush.

There are three indicating marks on the scale but it is possible to adjust at any position along its range; it is necessary to lock setting to maintain setting in position. Center position has a detent to indicate 1/2 of hole closed.

Smaller indicating mark: Hole open.

Center indicating mark: 1/2 of hole closed, position with detent.

Bigger indicating mark: Greater part of hole closed.

Types of Operation for Double Eliminators:

• Normal operating position is with indicating mark aligned with arrow on metering box. This position means approximately 1/2 of seed hole is covered and should provide good elimination of doubles for most seed sizes and forms. If double elimination performance is inconsistent and can not be corrected by variation of vacuum level or by reduction of planting speed it may be necessary to move adjustment to smaller mark (hole open) or to bigger mark (greater part of hole closed).
• Seed disk hub height adjustment is critical for adequate performance. Adjust seed disk hub so that it maintains a slight contact with metering box. Proper adjustment is reached if disk turns approximately one turn when turning hub manually.

  NOTE: If it is necessary to remove assembly, remove pin (A). Removal/installation of locking pin may be performed several times before there is the need to replace these components.
  If double eliminator adjustment turns out to be difficult, proceed as follows:
  1. Remove pin (A).
  2. Remove double eliminator.
  3. Lubricate double eliminator assembly with graphite powder.
  4. Reinstall double eliminator in inverse order of removal.
  5. Move double eliminator along whole range of adjustment do assure efficient operation.
