Maintenance Tips

Concave Adjustment: Regularly check and adjust concave clearance to ensure optimal threshing and minimize grain damage. Proper spacing is crucial for different crop types and conditions.
Belt and Chain Tension: Inspect and maintain proper tension on all belts and chains. Loose belts can slip, reducing efficiency, while overtightening can cause premature wear.
Sieve and Chaffer Cleaning: Regularly clean the sieves and chaffers to remove debris and prevent plugging. Clogged sieves reduce cleaning efficiency and can lead to grain loss.
Bearing Greasing: Grease all bearings according to the manufacturer's recommendations. Proper lubrication prevents overheating and extends bearing life.
