Drive combine over end rows or bumps to jar and shake dirt loose. Stop engine and remove key.

Open or remove all doors and drain holes.

CAUTION: Sound horn (A) to clear everyone from area.

Start engine and let separator run until chaff stops coming out rear. Lower engine rpm to low idle and engage separator several times. The "jogging" of separator at low idle removes dirt from inside of cylinder. Move throttle to high rpm and run for a few minutes. Repeat cycle until chaff no longer comes out of rear. Stay clear of the combine when chaff discharges. Raise reel until it stops. Also engage unloading auger to empty it.

Stop engine and remove key.
