Catalytic Converter: Description and Operation

There is no regularly scheduled maintenance on any Mopers stainless steel catalytic converter body. Excessive heat can result in bulging or other distortion, but excessive heat will not be the fault of the
converter. If unburned fuel enters the converter, overheating may occur. If a converter is heat-damaged, correct the cause of the damage at the same time the converter is replaced. Also, inspect all other components of the exhaust system for heat damage.
Unleaded gasoline must be used in gas engines to avoid contaminating the catalyst core.
