6LY3 Operation Manual
A
DANGER
FIRE AND EXPLOSION
HAZARD!
• Diesel fuel is extremely
flammable and explosive
under certain conditions.
• Be sure to place the diesel fuel
container on the ground when
transferring the diesel fuel
from the pump to the
container. Hold the hose
nozzle firmly against the side
of the container while filling it.
This prevents static electricity
buildup which could cause
sparks and ignite fuel vapors.
• NEVER place diesel fuel or
other flammable material such
as oil, hay or dried grass close
to the engine during engine
operation or shortly after shut
down.
• Failure to comply will result in
death or serious injury.

A
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.

CAUTION
• Only use diesel fuels
recommended by Yanmar for
the best engine performance,
to prevent engine damage and
to comply with EPA warranty
requirements.
• Only use clean diesel fuel.
• NEVER remove primary
strainer from the fuel tank filler
port. If removed, dirt and
debris could get into the fuel
system causing it to clog.
