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.
IMPORTANT: This machine is equipped with the
engine that meets Interim Tier 4 emission
requirements. Never attempt to modify the inlet
and exhaust system.
Exhaust gas color is normally transparent or light blue.
Although exhaust gas color slightly becomes white
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
any abnormality. In addition, check that no abnormal
noise is heard coming from the engine or muffler.
