412 MAINTAINING YOUR VEHICLE
WARNING!
To maintain your vehicle safely and avoid personal injury, follow these
guidelines:
• Never spray or pour diesel fuel, flammable liquid or starting fluids
(ether) into the air cleaner assembly, air intake piping or turbocharger
inlet in an attempt to start the vehicle, unintended engine acceleration
may occur.
• Do not use alcohol or gasoline as a fuel blending agent. They can be
unstable under certain conditions and be hazardous or explosive
when mixed with diesel fuel.
• If an engine has been operating and the coolant is hot, allow the
engine to cool before you slowly loosen the filler cap and relieve the
pressure from the cooling system.
• To avoid burns, remember that the engine components will stay hot
after the engine is shut off.
• Do not use gasoline or other flammable materials to clean parts.
Always use approved cleaning solvents.
• Relieve all pressure in the fuel, oil and cooling systems before any
lines, fittings or related items are removed or disconnected. Be alert
for possible pressure when disconnecting any device from a system
that utilizes pressure. Do not check for pressure leaks with your hand.
High pressure oil or fuel can cause personal injury.
• Important: All maintenance other than that listed in this manual, as
well as some procedures listed here, MUST be performed by your
authorized dealer. Your authorized dealer has been trained and has
the necessary parts to maintain your engine.
WARNING!
Do not open the high pressure fuel system with the
engine running. Engine operation causes high fuel
pressure. High pressure fuel spray can cause serious
injury or death.
