DANGER: Exhaust inhalation hazard. Ventilate
the shop with fresh air when carrying out warming
up warm-up operation indoor. Failure to do so may
cause asphyxiation from exhaust gas, resulting in
death or severe injury.
Exhaust gas color is normally transparent or light
blue. Although exhaust gas color is a light white color
immediately after the engine is started or quickly
accelerated, this symptom is not abnormal. If the
exhaust gas color turns black, white, brown, or gray,
check the engine oil level and the fuel supply system for
problems. In addition, check that no abnormal noise is
heard coming from the engine or muffler.
