Excessive black smoke from exhaust during operation

Safety first: Ensure adequate ventilation around the generator. Avoid breathing exhaust fumes.

• Check load: Verify that the generator is not overloaded. Reduce non-essential loads and observe if smoke decreases.
• Inspect air filter: Remove and inspect the air filter element. Replace if dirty or restricted.
• Check intake and exhaust paths: Ensure no obstructions in the intake ducting or exhaust outlet.
• Monitor engine response: If smoke persists with normal load and clean air filter, injectors or turbocharger may require professional testing and overhaul.
