To ensure safe operation
Carbon Monoxide Poisoning Hazard
Exhaust contains poisonous carbon monoxide, a colorless and odorless gas.
Breathing exhaust can cause loss of consciousness and may lead to death.
• If you run the engine in an area that is confined or even partially enclosed, the
air you breathe could contain a dangerous amount of exhaust gas. To keep
exhaust gas from building up, provide adequate ventilation.
• Replace faulty muffler.
• Do not operate the engine in a confined space where dangerous carbon
monoxide fumes can collect.
