Safety regulations for working with the power system

The fuel system is under pressure! Before releasing the hose connections, the fuel pressure must be relieved. To do this, briefly remove and screw on the fuel filler cap. Cover the joint with a thick, clean cloth. Put on goggles and only then, carefully releasing the connection, release the fuel pressure.

Attention: On the AXU petrol engine with direct injection, only the low pressure circuit can be depressurized in this way (up to 5 bar). To relieve pressure in the high pressure circuit (up to 100 bar) special equipment is required.

The high-pressure circuit includes fuel lines from the high-pressure pump attached to the rear of the cylinder head to the injectors. In a diesel engine with a working volume of 1.9 liters, the temperature of the high-pressure fuel lines, and in a diesel engine equipped with pump injectors, respectively, the temperature of the fuel can reach +100°C in extreme cases. Allow the fuel to cool before releasing the fuel lines, as there is a serious risk of scalding.

• No open flames, no smoking, no hot or very hot parts near the work area. Danger of accident! Prepare a fire extinguisher.
• Be sure to ensure good ventilation in the workplace. Fuel vapors are poisonous.
• Wear protective gloves.
• Wear safety glasses.
