• Clogged Air Filter: Clean or replace the air filter.
• Restricted Airflow: Ensure the air intake and outlet are not blocked.
• Poor Combustion: May indicate issues with fuel quality, fuel pump, or glow plug.

9.3. Excessive Smoke or Unusual Odor

• Incomplete Combustion: This can be caused by incorrect fuel-air mixture, low voltage, or a faulty glow plug.
• Clogged Exhaust: Check the exhaust pipe for blockages.
• Fuel Quality: Ensure clean, appropriate diesel fuel is used.
• First Use: A small amount of smoke or odor may occur during the initial few minutes of the first operation as manufacturing residues burn off.

9.4. Unusual Noise During Operation

• Loose Components: Check for any loose mounting screws or parts.
• Fan Obstruction: Ensure nothing is obstructing the fan blades.
• Fuel Pump Noise: The fuel pump makes a rhythmic ticking sound during operation, which is normal. Excessive or irregular noise may indicate an issue.
