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.

- 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.
