Cleaning Out the Combine

CAUTION: To prevent injury, never clean the combine with the engine running and the separator engaged.

The following instructions are recommended when cleaning out the combine for certified seed crops or when transporting the combine inter-state.

CAUTION: Block header safely so it will not move. Lower reel safety stops.

Remove header from combine.

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

Open or remove all doors and drain holes.

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

Stay clear of combine when discharging chaff.

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 the rear of the combine.

CAUTION: Keep bystanders clear of combine when discharging chaff.

Drive combine straight back 3 m (10 ft.) onto blocking so right-hand side is about 150 mm (6 in.) higher, or park on incline so dirt can run out.

Stop engine and remove key.
