Maintenance Tips
- Concave Adjustment: Regularly check and adjust concave clearance according to the crop being harvested. Proper concave settings minimize grain loss and damage.
- Belt and Chain Tension: Inspect belt and chain tension regularly, especially before and during harvest. Loose belts and chains can lead to slippage, reduced performance, and premature wear.
- Sieve and Chaffer Cleaning: Clean sieves and chaffers daily to prevent clogging and ensure optimal grain cleaning. Remove any accumulated debris and adjust settings as needed.
- Bearing Greasing: Grease all bearings according to the manufacturer's recommendations. Proper lubrication prevents bearing failure and extends the lifespan of critical components.
