Precautions - Mercury MerCruiser D2.8L D-Tronic Service Manual

SERVICE MANUAL NUMBER 22

Precautions

ALWAYS disconnect battery cables from battery BEFORE working on fuel system
to prevent fire. This eliminates the engine wiring as a potential source of ignition.
FIRE HAZARD: Be careful when changing fuel system components; diesel fuel is
flammable. Fuel leakage from any part of the fuel system can be a fire hazard which
can cause serious bodily injury or death. Ensure that ignition key is OFF. Do NOT
smoke or allow sources of open flame in the area while changing fuel system com-
ponents. Do NOT allow fuel to come into contact with any hot surface which may
cause it to ignite.
FIRE HAZARD: Wipe up any spilled fuel immediately. Dispose of rags appropriately.
Dispose of fuel soaked rags, paper, etc. in an appropriate airtight, fire-retardant
container. Fuel soaked items may spontaneously ignite and result in a fire hazard
which could cause serious bodily injury or death.
FIRE HAZARD: Fuel leakage from any part of the fuel system can be a fire hazard which
can cause serious bodily injury or death. Careful periodic inspection of entire fuel
system is mandatory, particularly after storage. All fuel components including fuel
tanks, whether plastic, metal or fiberglass, fuel lines, primers, fittings, and fuel filters
should be inspected for leakage, softening, hardening, swelling or corrosion. Any sign
of leakage or deterioration requires replacement before further engine operation.
Safety glasses should be worn while working on fuel injection system. The fuel injection
pump will generate pressures in excess of 13790 kPa (2000 psi). Use caution when
removing injectors, injector lines, or bleeding air from injection system.
Keep injectors and injection pump fittings clean. Do NOT allow dirt to enter fittings
when removing or installing lines. Dirt will cause injectors or injection pump to
malfunction.
IMPORTANT: Mercury MerCruiser does not recommend fuel injectors be
disassembled for service. If an injector tester is not available, substitute a new
injector for any injectors thought to be faulty.
IMPORTANT: Always wash hands and use clean tools when working on fuel injection
system.
