Maintenance Tips

Concave Adjustment: Regularly inspect and adjust concave clearance to ensure proper threshing and minimize grain damage. Consult the operator's manual for specific recommendations based on the crop being harvested.
Belt and Chain Tension: Check and maintain proper tension on all belts and chains to prevent slippage, wear, and potential breakdowns during operation. Refer to the service manual for tension specifications.
Sieve and Chaffer Cleaning: Regularly clean the sieves and chaffer to remove debris and prevent plugging, which can reduce cleaning efficiency and increase grain loss.
Bearing Greasing: Grease all bearings according to the lubrication schedule outlined in the operator's manual to ensure smooth operation and extend bearing life.
