B. SAFETY CHECKLIST & PRECAUTIONS WHEN DRAINING THE FUEL SYSTEM
•
•
•
•
1.
Always remember “SAFETY FIRST”.
Be extremely careful when handling fuel to prevent fires from occurring.
Before beginning work on the fuel system, perform the following safety check list.
Before removing any fuel system part, drain all fuel to prevent spilling.
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).
2.
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.
3.
FIRE EXTINGUISHER
Have a fire extinguisher ready and available before beginning work.
4.
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.
5.
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.
6.
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.
7.
PREVENT THE FUEL FROM CONTACTING OTHER PARTS
DO NOT allow the fuel to come in contact with any parts made of rubber or leather.
8.
ASSIGN A SAFETY SUPERVISOR
Assign a safety supervisor to be in charge of all safety precautions and fire hazards around the work area.
33
34
35
C. DISCHARGE THE FUEL SYSTEM PRESSURE
• DO NOT disconnect any part of the fuel system until you have discharged the fuel system
pressure.
• Even after discharging the fuel system pressure, place a piece of cloth around the tubes,
pipe, hoses and connectors as you separate them to reduce the risk of fuel spraying on
yourself, in the engine compartment and onto other parts.
• For additional repair information, please reference the appropriate repair manual in TIS for
the vehicle you are working on.
1.
CHECK FOR DTCs
2.
RECORD THE RADIO STATION PRESETS
3.
DISCONNECT THE NEGATIVE (-) BATTERY TERMINAL
