Excessive white smoke from exhaust, especially on cold start

Safety first: Operate the generator in a well‑ventilated outdoor area. Avoid inhaling exhaust.

• Warm‑up: Allow the Scheppach generator to warm up under light load for several minutes. Some white smoke on cold diesel start can be normal.
• Check coolant level: On liquid‑cooled models, monitor coolant level. If it drops and white smoke persists with sweet smell, suspect head gasket or liner issues.
• Fuel quality: Ensure diesel fuel is fresh and appropriate for ambient temperature. Water‑contaminated fuel can cause white smoke; drain and replace if needed.
• Professional diagnosis: Persistent heavy white smoke requires compression testing and inspection of injectors and head gasket by a technician.
