SAFETY
WARNING
Piercing Hazard
Avoid skin contact with high-
pressure diesel fuel spray
caused by a fuel system leak
such as a broken fuel injection
line. High-pressure fuel can
penetrate your skin and result in serious
injury. If you are exposed to high-pressure
fuel spray, obtain prompt medical treatment.
NEVER check for a fuel leak with your
hands. ALWAYS use a piece of wood or
cardboard. Have your authorized Yanmar
Marine dealer or distributor repair the
damage.
Burn Hazard
Some of the engine surfaces
become very hot during
operation and shortly after
shutdown. Keep hands and
other body parts away from
hot engine surfaces.
Sudden Movement Hazard
ALWAYS stop the engine before beginning
service.
Exhaust Hazard
NEVER block windows, vents
or other means of ventilation if
the engine is operating in an
enclosed area. All internal
combustion engines create
carbon monoxide gas during operation and
special precautions are required to avoid
carbon monoxide poisoning.
