DANGER
FIRE AND EXPLOSION
HAZARD!
• Diesel fuel is extremely
flammable and explosive under
certain conditions.
• Before you operate the engine,
check for fuel leaks. Replace
rubberized fuel hoses every
two years or every 2000 hours
of engine operation, whichever
comes first, even if the engine
has been out of service.
Rubberized fuel lines tend to
dry out and become brittle
after two years or 2000 hours
of engine operation, whichever
comes first.
• Failure to comply will result in
death or serious injury.
