Initial use You should not use too much air to prevent the granulate from being blown out of the seed The metering units must first run in during initial furrow. use. With higher air volumes dust will also accumulate increasingly on the components. The function of the grain count sensor can be affected by this. - Page 119 NOTE The required fan speed may differ with the ¾ micro-granulate auxiliary equipment.
