Maintenance Tips
- Concave Adjustment: Regularly check and adjust concave clearance to ensure proper threshing without grain damage. Refer to the operator's manual for recommended settings based on the crop being harvested.
- Belt and Chain Tension: Inspect all belts and chains for proper tension and wear. Loose belts or chains can lead to slippage and reduced performance, while worn components should be replaced promptly to prevent breakdowns.
- Sieve and Chaffer Cleaning: Keep the sieves and chaffer clean to ensure efficient grain separation and minimize losses. Regularly blow out debris and inspect for damage.
- Bearing Greasing: Follow the recommended greasing schedule for all bearings to prevent premature wear and failure. Use the correct type of grease as specified in the operator's manual.
