Safety precautions
Warning!
The fuel system is pressurized! Before loosening hose connections or opening the test connection, place a cloth around the connection. Then carefully pull hose off or remove the plug.


To prevent injuries to persons and/or damage to the fuel injection and ignition system, the following must be noted:

  • ◆ Do not touch or disconnect ignition wiring when the engine is running or being turned at starter speed.
  • ◆ The ignition must be switched off before connecting or disconnecting injection or ignition system wiring or tester cables.
  • ◆ If the engine is to be turned at starter speed without starting, e.g. when checking compressions, separate connector from speed sender (on lower part of bracket on cylinder head, left).
