Safety Precautions



Safety Precautions

CAUTION: When doing any repair work, especially in the engine compartment, pay attention to the following due to clearance issues:
- Route all the various lines (e.g. for fuel, hydraulics, EVAP canister system, coolant, refrigerant, brake fluid and vacuum lines and hoses) and electrical wiring so that the original positions are restored.
- Ensure sufficient clearance to all moving or hot components.
- Fuel system is under pressure. Before opening the system place a cloth around the connection. Then release pressure by carefully loosening the connection.


Always observe the following when removing and installing fuel level sensors or fuel delivery unit from full or partially filled fuel tanks.
- Already before starting work, switch on exhaust extraction system and place an extraction hose close to the sensor installation opening of fuel tank to extract escaping fuel fumes.

If no exhaust extraction system is available, a radial fan (as long as motor is not in airflow) with a displacement greater than 15 cu.m/h can be used.

- Prevent fuel from contacting skin. Wear fuel-resistant gloves
