Excessive white smoke from exhaust, especially on startup

Safety first: Operate the generator in a well-ventilated area. Avoid prolonged running if coolant loss is suspected.

• Check coolant level: Monitor coolant level in radiator/header tank. Unexplained loss with white smoke may indicate head gasket issues.
• Observe smoke behavior: If smoke clears as engine warms and load is applied, it may be normal for cold starts. Persistent dense white smoke suggests a fault.
• Check fuel quality: Ensure diesel is clean and appropriate for ambient temperature.
• Professional diagnosis: If coolant loss or misfire is present, have compression and injector tests performed by a technician.
