Maintenance Tips

- Belt and Chain Tension: Inspect all belts and chains for wear and proper tension. Loose or worn belts and chains can cause slippage and reduce efficiency.
- Sieve and Chaffer Cleaning: Clean sieves and chaffers frequently to prevent buildup of debris, which can reduce cleaning performance and increase grain loss.
- Bearing Greasing: Regularly grease all bearings according to the manufacturer's recommendations to ensure smooth operation and prevent premature failure. Pay close attention to header bearings, cylinder bearings, and unloading auger bearings.
