Warning:
Gasoline or gasoline vapors are highly flammable.
A fire could occur if an ignition source is present. Never drain or
store gasoline or diesel fuel in an open container, due to the
possibility of fire or explosion. Have a dry chemical (Class B)
fire extinguisher nearby. |

Warning:
Remove the fuel tank cap and relieve the fuel
system pressure before servicing the fuel system in order to reduce
the risk of personal injury. After you relieve the fuel system
pressure, a small amount of fuel may be released when servicing the
fuel lines, the fuel injection pump, or the connections. In order
to reduce the risk of personal injury, cover the fuel system
components with a shop towel before disconnection. This will catch
any fuel that may leak out. Place the towel in an approved
container when the disconnection is complete. |
