Refuelling
Use summer or winter fuel depending on the season. See also "Diesel fuels"
( page 60).
Bleeding the fuel system
The fuel system is b led when the engine is started after refuelling if the fuel system was previously allowed to run dry. Contin-uous bleeding takes place automatically in the filter.
Checking the batteries
Only use batteries which are completely filled and have been perfectly maintained.
Grease the battery terminals with acid-proof grease (terminal grease).
!
Make sure that utmost cleanliness is observed while refuelling and that no water is allowed to enter the tank.
i
To ensure that the fuel system can b e bled, the battery must have enough charge when the engine is started.
Risk of burning
G
The acid contained in batteries burns skin and eyes on contact.
Do not allow acid to come into contact with your skin, eyes or clothing.
Wear suitable protective clothing, as battery acid can burn through normal c lothing. In addition, protective gloves and safety goggles should be worn.
Rinse acid splashes off immediately with c lean water and consult a doc tor if nec-essary.
Risk of explosion
G
Gases escaping from batteries can explode and injure people.
Therefore, do not allow fire, naked flames, smoking or the creation of sparks in the vi-cinity of batteries.
i
The cable cross-sections are depend-ent on the distance between the bat-tery an d the starter motor.
Commissioning
5
Carry out the work listed under "Prepara-tion for commissioning" ( page 42) be-fore operating the engine for the first time.
Switch on the operating current.
Start the engine with the setpoint value sensor at idling position (e.g. accelera-tor pedal), for instance by operating the starter switch on the equipment or Start button2 on the engine, ( see page 47).

Starting the engine for the first time
i
As a safety feature, the Telligent® en-gine system is equip ped with a function that o nly allows the engine to be start-ed with the transmission in neutral.
Risk of burns
G
The engine bec omes very hot while it is run-ning and remains so for some time after it has stopped. It will cause burns if you touc h it.
Before starting any work on the engine, al-low all engine parts to cool down or else wear suitable gloves and items of clothing to protect yourself against hot engine compo-nents.
Operation
CommissioningTo check the coolant level:
5
Leave the engine running at moderate speeds for approximately 5 minutes.
If the coolant temperature is below 50 °C, check the coo lant level again and add coolant if necessary.
Risk of injury
G
There is a danger of limbs being caught, trapped, crushed or torn off by rotating en-gine parts. Therefore you should:
Keep a safe distance between yourself and rotating engine parts, including when the engine is being started.
Wait until all engine parts have come to a standstill before carrying out any work on the engine.
Wear work clothing which is fastened and close-fitting. Wear a hair net if nec-essary. Remove jewellery such as watches and necklaces.
Risk of scalding
G
The cooling system is pressurised. Hot cool-ant can spray out when the cooling system is opened and scald your skin and eyes.
Only open the cooling system at coolant temperatures below 90 °C.
Unscrew the sealing cap slowly and re-lease any excess pressure completely before opening the cap fully.
Wear suitable protective gloves, protec-tive clothing and safety goggles when handling c oolant.
Risk of poisoning
G
There is a risk of poisoning if coolant is swal-lowed.
Never swallow coolant.
Never put coolant into container nor-mally used for beverages.
Store coolant out of the reach of chil-dren.
Commissioning
5
Only close the heating system valves o nce the engine has been running for a brief pe-riod. Top up with coolant if necessary.
Check the engine for leaks.
Check the hose fittings, hose clamps and pipe co nnection s on the engine as well as the oil feed and return lines o n the exhaust gas turbocharger fo r leaks and firm seating, and tighten if neces-sary.
Check the engine oil level approximate-ly 5 minutes after stopping the engine and add oil up to the maximum mark on the dip stick if necessary.
Check for firm seating of mountings on the engine.
Check the securing bolts on the ex-haust manifold, engine mountin gs, coolant pump, starter motor and air compressor for firm seating.
!
If a heating system is connected to the cooling system, all heating system valves must be o pened while the co ol-ing system is beol-ing topped up.
Otherwise there might be too little coolant in the cooling system after fill-ing.
Operation
Commissioning5
Sta rting procedure
In the case of vehicle engines, secure the vehicle to prevent it from rolling away acci-dentally:
Apply the parking brake.
Shift the transmission into neutral.
Place wheel chocks in front of or be-hind the wheels.
Insert the key into the ignition and turn it to the driving position.
The following indicator and warning lamps light up:
1 Charge current indicator lamp 2 Electronic system warning lamp 3 Flame-start system indicator lamp or
grid heater
Start the engine within 30 secon ds o f the flame-start indicator lamp going out.
Starting the engine
Risk of injury
G
If not properly secured, a vehicle might acci-dentally be set in motion when the engine is started, knocking people down or trapping them. Before starting the engine:
Prevent the vehicle from rolling away by applying the parking brake and, if neces-sary, by placing chocks under the wheels.
Shift the transmission into neutral.

Starting the en gine for the first time ( see page 44).
Carry out special measures before starting the engine when it has been stopped for a long period, see the
"Cleaning/protective treatment"
sec- page 55).
i
At outside temp eratures below –30 °C we recommend preheating the coolant (e.g. using an electric preheating de-vice)

using Start button 2 on the engine.
Monitor the oil pressure gauge
immedi-ately after starting the engine. At extremely cold temp eratures, do not
place the cold engine under a full load im-med iately after starting.
!
Keep the engine running at idling speed un til an oil pressure reading is dis-played. If no oil pressure is displayed after approximately 10 seconds, switch off the engine. Determine the cause; see the "Oil pressure" section ( page 51).
i
If necessary, break off the starting procedure after a maximum of 20 sec-onds, and then repeat after app roxi-mately 1 minute.
The charge current indicator lamp and electro nic system warning lamp must go out after the engine has started. If they remain on, there are malfunctions;
( see page 49) and ( page 50).
i
The indicator lamp for the flame-start system lights up for approximately 2 seconds (function check, flame-start system not in operation) to approximate-ly 20 seconds (maximum preglow time) depending on the outside temperature.
If the indicator lamp for the fl ame-start system does not go out after approxi -mately 20 s ec onds, there is a fault; s ee the "Telligent® engine s ystem" sec tion ( page 50).
i
The grid heater is controlled by the drive control unit or the ADM control unit. The preglow time lasts for approximately 30 seconds and depends on the temper-ature of the coolant and the charge air.
During the preglow time, the indicator lamp lights up and then goes out once the preglow time has finished.
