Safety precautions


WARNING!
The fuel system is pressurized! Before loosening hose connections or opening the test connection, wrap a cloth around the connection. Then release pressure by carefully pulling off the hose or carefully unscrewing sealing plug.

To prevent injuries to persons and/or damage to the fuel injection and ignition systems, observe the following precautions:
- Do not touch or disconnect ignition wiring when the engine is running or being turned over via the starter.
- Switch OFF the ignition before connecting or disconnecting fuel injection or ignition system wiring or tester cables.
- If the engine is to be turned at starter speed, without starting:

- Disconnect 5-pin harness connector -1- from ignition coil Power Output stage -2-.







Observe following if test instruments are required during test drive:

- Test and measuring instruments must be secured to rear seat and operated by a 2nd person from this location. If test and measuring instruments are operated from front passenger's seat and the vehicle is involved in an accident, there is a possibility that the person sitting in this seat may receive serious injuries when the airbag is triggered.

WARNING!
Fuel supply lines are under pressure! Before removing from hose connection wrap a cloth around the connection. Then release pressure by carefully pulling hose off connection.

When removing and installing the fuel gauge sender or fuel pump (fuel delivery unit) from a full or partly full fuel tank observe the following:
- Before starting work, switch on exhaust extraction system and place an extraction hose close to the sender opening in the fuel tank to extract escaping gasoline fumes. If no exhaust extraction system is available, a radial fan (as long as motor is not in air flow) with a displacement greater than 15 cubic.m/h may be used.
- Prevent skin contact with fuel! Wear fuel-resistant gloves!
