APPENDIX····································································································· SECTION X. 5 SAFETY PRECAUTIONS 1. Always remember “SAFETY FIRST”. 2. Be extremely careful when handling fuel to prevent fires from occurring. 3. Before beginning work on the fuel system, perform the following safety check list. 4. Before removing any fuel system part, drain all fuel to prevent spilling. A. AIR VENTILATION Perform work in a well ventilated area. DO NOT work underground or in an area where fuel vapors may fill the room due to poor ventilation. Quickly clean up any spilled fuel with a dry cloth and dissipate the fuel vapors. Dry all cloths that have come in contact with fuel in a well ventilated area and dispose of them properly (according to applicable local regulations). B. FIRES AND IGNITION SOURCES ARE STRICTLY PROHIBITED Fires and ignition sources are prohibited while working on the fuel system. Clearly display the sign found on the next page stating “WORKING WITH GASOLINE, NO FIRES OR IGNITION SOURCES”. Smoking is prohibited near the work area. DO NOT work in areas where there are welders, grinders, drills, electric motors, heaters, etc. DO NOT use work lamps or any other electrical appliance due to the risk of sparks flying from the power switch or a rise in temperature. DO NOT use metal hammers while working, due to the risk of flying sparks. DO NOT start any engines or perform any of the above in neighboring work bays. C. FIRE EXTINGUISHER Have a fire extinguisher ready and available before beginning work. D. PREVENT STATIC ELECTRICITY To help prevent static electricity, lightly wet the floor with water, but not to the point where it creates a hazardous working condition. Place appropriate warning cones or stand signs around the area as a caution. E. PRECAUTIONS WHEN USING A LIFT For bays equipped with auto lifts, cover all access cover joints with duct tape. In the event that fuel has leaked inside the auto lift, remove the access cover and clean up any spilled fuel. Dissipate fuel vapors until the smell is gone. F. PREVENT THE FUEL FROM SPRAYING When disconnecting any fuel tubes, pipes, hoses or connectors there may still be some pressure remaining, even after discharging the system. To prevent the fuel from spraying, cover the tubes, pipes or connectors with a shop rag before disconnecting. Remember to always wear protective goggles especially when disconnecting fuel tubes, pipes, hoses or connectors. G. PREVENT THE FUEL FROM CONTACTING OTHER PARTS DO NOT allow the fuel to come in contact with any parts made of rubber or leather. H. ASSIGN A SAFETY SUPERVISOR Assign a safety supervisor to be in charge of all safety precautions and fire hazards around the work area. 6 7 COMPONENTS 8 9 10 REMOVE THE FUEL TANK SUB-ASSY 1.

FILL THE FUEL TANK WITH FUEL 21. INSPECT FOR FUEL LEAK NOTE: Make sure that more than 3 hours have passed since tightening the insert nut of the propeller shaft. 22. INSPECT FOR EXHAUST GAS LEAK 23. CHECK FOR DTCs 32 DISPOSE OF FUEL TANK PROPERLY TO PREVENT FIRE (DISCHARGE FUEL VAPOR) NOTE: The fuel tank is filled with fuel vapor after removing the fuel and is in dangerous condition. So make sure to discharge the fuel vapor inside the tank following the instructions below. NOTE: Make sure to perform work in a well ventilated area and strictly prohibit fire and ignition sources since fuel vapor is going to be discharged from the fuel tank. NOTE: Wear an organic solvent mask as needed to prevent feeling sick by inhaling fuel vapor (organic solvent), while making sure natural ventilation. 1. DISCHARGE FUEL VAPOR a) Before drying with compressed air, remove the remaining fuel inside fuel tank into a new tank using a hand operated pump (DO NOT use electric pump as there is a risk of fire). NOTE: Never use the manual pump used to transfer gasoline to transfer kerosene. In case that gasoline remains in the pump, there is a risk of a fire accident. b) Blow compressed air from each hole of the fuel tank in order to evaporate all the fuel remaining inside the fuel tank. 33 ◄ VERIFY REPAIR QUALITY ► – Ensure that 3 hours have passed since installing and tightening the prop shaft insert nut before starting the engine – Ensure there are no fuel leaks around the fuel tank, below the vehicle, or around the filler neck – Ensure there are no DTC’s present – Ensure the pump is operational by driving the vehicle under various loads.
