WARNINGThe spilling of fuel is unavoidable during this operation. Ensure that all necessary precautions are taken to prevent fire and explosion.
WARNINGDo not carry or operate cellular phones when working on or near any fuel related components. Highly flammable vapors are always present and may ignite. Failure to follow these instructions may result in personal injury.
WARNINGDo not smoke or carry lighted tobacco or open flame of any type when working on or near any fuel related components. Highly flammable vapors are always present and may ignite. Failure to follow these instructions may result in personal injury.
WARNINGIf fuel contacts the eyes, flush the eyes with cold water or eyewash solution and seek immediate medical attention.
WARNINGWash hands thoroughly after fuel handling, as prolonged contact may cause irritation. Should irritation develop, seek medical attention.
CAUTIONDiesel fuel injection equipment is manufactured to very precise tolerances and fine clearances. It is therefore essential that absolute cleanliness is observed when working with these components. Always install blanking plugs to any open orifices or lines. Failure to follow this instruction may result in foreign matter ingress to the fuel injection system.
