6. Fit seed disk (A) into housing. Hold seed disk stationary and rotate hub handle (B).

NOTE: Seed disk should turn smoothly with light contact or a small gap between seed disk (A) and meter housing. Seed should not leak around circumference of meter. When planting small seed such as sorghum or sugar beets, seed disk must lightly contact meter housing to prevent seed leakage.

7. Turn seed disk by hand and check gap between seed disk and meter housing in section (C). If disk turns too hard or if seed leaks through gap, repeat procedure.
