Maintenance Tips

Concave Adjustment: Regularly check and adjust the concave clearance based on the crop being harvested to minimize grain damage and maximize threshing efficiency. Refer to the operator's manual for recommended settings.
Belt and Chain Tension: Inspect belt and chain tension regularly, especially after the first few hours of operation and then periodically throughout the season. Loose belts and chains can cause slippage, reduced performance, and premature wear.
Sieve and Chaffer Cleaning: Keep the sieves and chaffer clean to ensure efficient grain separation and minimize grain loss. Use compressed air to remove debris and crop residue.
Bearing Greasing: Follow the recommended greasing schedule for all bearings on the combine, including those on the header, threshing cylinder, and cleaning system. Proper lubrication is crucial for extending bearing life and preventing costly repairs.
