Adjusting Fan Speed

Before adjusting fan speed, open chaffer and sieve to the maximum recommended openings, as in "Combine Settings " chart). Then start with the lowest fan speed suggested and gradually increase fan speed until the maximum amount of chaff is expelled without blowing grain out of the combine or into the tailings return.

Check the results carefully. After reaching the maximum acceptable fan speed, continue to make minor adjustments to the chaffer (Consult "Adjusting Sieves"). If necessary, change fan speed again, until the best result is achieved.

NOTE: Always check results before attempting further adjustments.
