Excessive “matting” of grain, chaff and broken straw on the upper sieve can be pre- vented by having sufficient volume of wind. The wind blast also helps to fluff up the material. The speed can be infinitely varied with crank (1). The crank is decelerated by a spring and is therefore pro- tected against unintended misadjustments. Engage the threshing mechanism. Set the diesel engine speed to fast idling speed. 2 1 + Note! Constructive conditions. Machine damage.
Adjust the fan speed only when the threshing mechanism is engaged. 44 Adjust fan speed with crank (1) until the desired speed is shown on gauge (2). 19634 The speed must be set depending on the crop. See threshing chart. Basic rule: Set the fan speed as high as possible, depending on crop conditions. 82936 11.8.2 Adjusting the wind board Observe the general warnings at the beginning of the "Fieldwork" chapter. 00 0293 210 2 - BA DOMINATOR 150/140/130 - 12/09 219 Fan speed Higher Turn crank clockwise (+) Lower Turn crank anti- clockwise (–) Gauge value x 100 = approx. fan speed in rpm.
