1. Do not use take-up devices, such as ropes or chains, that are damaged or Wear work gloves when handling wire ropes.

2. When the diesel engine is running, make sure that no objects come in contact with the fan. Objects that have fallen or protruded into the fan will be hurled back or destroyed and can damage the fan.

3. The diesel engine cooling system is hot and under pressure near the operating temperature. Avoid contact with parts carrying cooling water.Arisk of burns exists!

4. Check the cooling water level only when the end cover of the expansion tank

5. The diesel engine oil is hot near the operating temperature.Avoid skin contact with hot oil or parts carrying oil.

6. Wear safety goggles and work gloves when you are working on the battery.

2.6 Safety measures when starting

1. If no other instructions are received, start the diesel engine according to the provisions in the operator'smanual.

2. Start the diesel engine and then check all display devices and control equipment.

3. ventilation. supply.

2.7 Measures for safe maintenance

1. Do not perform any maintenance or repair work that you have not mastered.

2. Adhere to the prescribed times, or the times stated in the operator's manual, for recurring checks or inspections. To perform the maintenance measures, workshop equipment appropriate for the work is absolutely necessary.

3. at the end of this operator'smanual. The machine operator or maintenance personnel may only perform the work appropriate training.

4. Spare parts must meet the technical requirements established by the manufacturer.This is always ensured with original spare parts.

5. Wear safe work clothing during the maintenance.

6. If nothing else is stated in this operator'smanual, perform all maintenance

7. Tighten the screw connections released with the prescribed tightening torque during maintenance and repair work.

8. of oil, fuel and care products at the start of the maintenance or repair. Do not use any aggressive cleaning agents. Use lint-free cleaning cloths.

9. Before cleaning the machine with water, steam jet (high pressure cleaner) or other cleaning agents, cover or glue shut all openings into which, for safety or functional reasons, no water, steam or cleaning agents may penetrate. Especially at risk are the crankcase ventilation, electronics box, starter, alternator and exhaust after-treatment system.

Additional procedure:

• After cleaning, remove the covers or adhesions completely.

• After cleaning, inspect all fuel, diesel engine oil, and hydraulic oil lines for leaks, loosened connections, abrasion marks and damage.

• Rectify defects discovered immediately.

18. Work on electrical equipment of the machine may only be carried out by a skilled electrician, or by instructed persons under the direction and supervision of a skilled electrician, according to the electrical regulations.

19. Disconnect the battery when you are working on the electrical system and also remove the plug from the control unit when you are carrying out electric welding last.

2.8 Safety measures for diesel engines with electronic control units

1. Start the diesel engine only with permanently connected batteries.

2. Do not disconnect batteries when the diesel engine is running.

3. Start the diesel engine only with the control unit connected.

4. Do not use a rapid charger to start the diesel engine. Starting aid only with separate batteries.

5. To rapidly charge the batteries, the battery terminals must be removed. Follow the operating instructions for the rapid charger.

6. During welding work, the batteries must be disconnected and the two cables (positive and negative) must be securely connected to one another. Furthermore, the connecting plugs must be disconnected for all control units.

7. The connections of the control units may only be removed or attached when the tight with the prescribed tightening torque.

8. Incorrect polarity of the control unit supply voltage (e.g. through incorrect polarity of the batteries) can lead to destruction of the control units.

9. Screw connections on the injection system tight with the prescribed tightening torque.

Special instructions for work on the common rail system

10. If temperatures above 80 °C are expected (e.g. drying oven), the control units must be removed.

11. Use only suitable test leads for measurements on plug connections.

12. Sensors or actuators may not be connected individually or between external voltage sources for either inspection or testing purposes, but only in connection with the electronic control unit, since otherwise a risk of destruction or a danger of a malfunction of the diesel engine exists.

13. when the mating connector is mounted and attached. If the mating connector water.

14. Telephone and radio equipment which is not connected to an external antenna can lead to malfunctions of the vehicle electronics and thereby endanger the operational safety of the diesel engine.

2.9 Safety and emergency operation program for diesel engines with electronic control units

1. The diesel engine has an electronic control system, which monitors both the diesel engine and itself (self-diagnosis).

As soon as a fault is detected, one of the following measures is automatically initiated after assessment of the fault that arose:

• Output of an error message with error code.

• In connection with the vehicle diagnosis system, the error code is directly output via a display.

• Changeover to an appropriate substitute function for further, but limited operation of the diesel engine (e.g. constant emergency operation speed). HavefaultsimmediatelyresolvedbytheresponsibleLIEBHERRcustomer service.

2.10 Special instructions for work on the common rail system

1. When the diesel engine is running, the lines are constantly under a fuel pressure of up to 2200 bar.

• common rail system when the diesel engine is running.

2. The fuel escaping under pressure can penetrate the skin of the person and

• After stopping the diesel engine, observe at least a one minute waiting period until the pressure in the rail system has been relieved.

• Avoid residing near the diesel engine when it is running.

• Persons with pacemakers may not get closer than 20 cm to the running diesel engine.
