A WARNING
HIGH PRESSURE HAZARD!
• Avoid skin contact with high pressure

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.
• Failure to comply could result in death
or serious injury.
