Maintenance Tips

Concave Adjustment: Regularly check and adjust concave clearance to optimize threshing performance and minimize grain damage. Refer to the operator's manual for specific settings based on the crop being harvested.
Belt and Chain Tension: Inspect belt and chain tension before each use, ensuring they are properly adjusted to prevent slippage and premature wear. Replace worn belts and chains promptly.
Sieve and Chaffer Cleaning: Clean sieves and chaffers regularly to remove debris and ensure proper grain separation. Clogged sieves reduce efficiency and can lead to grain loss.
Bearing Greasing: Grease all bearings according to the manufacturer's recommendations to maintain smooth operation and extend bearing life. Pay particular attention to bearings on the header, cylinder, and unloading auger.
