Sieve and Chaffer Cleaning: Keep sieves and chaffers clean to ensure proper grain separation and minimize grain loss. Regularly remove debris and adjust settings as needed.
Bearing Greasing: Grease all bearings according to the manufacturer's recommendations to prevent premature wear and failure. Use the correct type of grease for each application.
