The fuel injection system remains under pressure after the engine has been turned OFF . Properly relieve fuel pressure before disconnecting any fuel lines. Failure to do so may result in fire or personal injury.
Do not allow fuel spray or fuel vapors to come in contact with a spark or open flame. Keep a dry chemical fire extinguisher nearby. Never store fuel in an open container due to risk of fire or explosion.
The radio may contain a coded theft protection circuit. Always obtain the code number before disconnecting the battery.
