Operational Adjustment of Harvest Performance Monitor (Continued)

1. If the needle moves towards "-" and stays there for more than 20 seconds, the combine harvester's ground speed is too low, i.e the harvester is not working hard enough. In this case, increase the combine harvester's ground speed until the needle returns to the center of the green sector.
2. If the needle moves towards "+" and stays there for more than 20 seconds, the combine harvester's ground speed is too high and grain losses are increasing. Reduce the combine harvester's ground speed until the needle returns to the green sector.
3. If the needle remains in the "+" sector even after ground speed has been reduced, this may be due to plugging at the straw walkers or sieve (cleaning shoe). In this case, check which of these components is causing the blockage by selecting them with the selector switch. If necessary, clean the relevant component. Once an acceptable performance level has been achieved, adjust the potentiometers of the display unit as described above.
4. If the harvesting conditions change during the course of the day (straw lying down or damp), or if the machine adjustment changes (fan speed), re-adjust the performance monitor. The sieve sensors may be moved fore-and-aft to any one of the three cut-outs in the sensor mountings (on right and left sides of combine).
5. Measure the losses from time to time to determine whether the combine harvester needs to be re-adjusted.
