In case you do not find an op manual- when you thresh the wheat, it should be clear of the hull, not like oats. Without checking the book, I would say the cyl speed would be 800-1100 rpm, concave clearance about 3/8 inch, (gauges on each side of the cylinder), chaffer about 1/2 to 5/8 inch, sieve about 3/8 inch, maybe less. You want it open enough to let the threshed seeds fall through- not the chaff. Lower cylinder rpm in mid-afternoon when things are dry and hot, higher rpm in AM and late PM when straw is tough. If grain is getting ground, lower speed, open concave. Speed makes feed. Open the door on the left end of the machine to check if grain is being threshed from straw. If not, close the concave first, increase cylinder speed next, until all heads are threshed from straw. Rest of the operation is cleaning trash from grain. Best to get the op manual, tells what to look for at each stage, and how to correct it for a good grain sample. If you have no experience with a combine, you need the manual just to ID the parts I mentioned! Farmers have only one chance each year to plant or harvest- too late when you screw it up!
