          \n\t\t\t\t\t\t\t\t\t

          3. Examine the Engine Condition<\/h3>

          The engine directly affects machine reliability and working efficiency.<\/p>

          Start the engine and check:<\/p>

          • Cold start performance<\/li>
          • Engine vibration<\/li>
          • Oil leakage<\/li>
          • Unusual engine noise<\/li>
          • Exhaust smoke color<\/li><\/ul>

            Different smoke colors may indicate different problems:<\/p>
