  2. Pull off the ejection wheel 2.

The number on the ejection wheel must be the same as the number on the singling disc 1. Deviating from this, the singling disc for squash requires an ejection wheel for the singling disc with 42 holes.

  1. Install the desired ejection wheel.
NOTE
If the singling unit is converted to rapeseed, beet or sorghum, perform steps 20 to 26.
  1. Clean the opto-sensor, Cleaning the opto-sensor.

The power consumption for seeding rapeseed, beets or sorghum is between 0.9 A and 1.2 A.
The power consumption for seeding coarse seed types is between 0.6 A and 1 A.

  1. To adjust the distance from the singling disc to the singling unit housing:
