Small Grain Combine Set Up Procedure

The information provided in this set up procedure is intended for use as a basic adjustment guide only. Some types of crop varieties and conditions may require deviations from the order given in procedure. Always preform one adjustment at a time.

Prior to Starting

NOTE: This procedure assumes that the platform is properly adjusted to prevent header loss.

1- Set combine to recommended initial settings for the grain crop, see "Combine Settings" in this Section.

2- Run combine until separator is completely FULL.

3- Power shutdown combine, see "Power Shutdown Procedure" in this Section.

4- Start set up procedure. Go to step 1 .

B5 Open precleaner in 3 mm (0.12 in.) increments.
Is free grain reduced?		 YES: GO TO STEP 4
NO: GO TO B6
     
B6 If there is still excessive chaff load:
Check separator residue (STEP 1-A1)
