Maintenance Tips
- Concave Adjustment: Regularly inspect and adjust concave clearance based on the crop being harvested. Ensure proper settings to optimize threshing and minimize grain damage.
- Belt and Chain Tension: Regularly check and maintain proper tension on all belts and chains. Loose belts and chains can lead to slippage, reduced performance, and premature wear.
- Sieve and Chaffer Cleaning: Regularly clean sieves and chaffers to remove debris and prevent plugging. Clogged sieves and chaffers reduce cleaning efficiency and increase grain loss.
- Bearing Greasing: Follow the recommended greasing schedule for all bearings. Proper lubrication extends bearing life and prevents costly downtime.
