11 Fieldwork 11.8 Cleaning unit 67087 The frogmouth sieves are adjustable for all grain sizes by levers. Lever (5) is used to adjust the upper frogmouth sieve over its full length, including the returns passthrough area (4). A 7 Lever (6) is used to adjust only the returns pass- through area (4). Adjust the grain sieving (3) of the upper frogmouth sieve with lever (5) so that the grain quantity is sieved after three fourths of the sieve area has been sieved. Always set the returns sieving (4) of the upper frogmouth sieve with lever (5) for all crop types wider than the grain sieving (3), so as to prevent ears not threshed out from falling through and get- ting into the returns.
Check returns. Adjust the lower frogmouth sieve with the lever (7) so that the crop in the grain tank corresponds to the desired quality. Check returns.

The display (3) allows the operator to determine how fast the machine can be driven without the reasonable grain loss limit being exceeded. 2 The grains carried out through the sieve fall on the sensor (2). The excited pulses are visualised by the meter lights of the display (3).
The sensitivity of the cleaning system display can be adjusted depending on the properties of the crop (grain moisture, grain shape, green part). 19648 49 00 0293 210 2 - BA DOMINATOR 150/140/130 - 12/09 221 Lower sieve adjusting lever (7) A Narrower sieve spacing B Wider sieve spacing
