Sieve and Chaffer Cleaning: Clean the sieves and chaffer regularly to remove debris and maintain optimal airflow for efficient grain cleaning.
Bearing Greasing: Follow the recommended greasing schedule for all bearings to ensure proper lubrication and prevent failure. Pay close attention to bearings in high-wear areas like the header and threshing unit.
