Safety precautions for operation
Daily inspection
Always perform visual inspection of the engine and engine bay before the engine is started and when the engine has been stopped after operation.
This will make it easy to detect any leakage of fuel, oil or coolant or any other abnormal condition that may require remedial action.
Refuelling
When refuelling, there is a risk of fire and explosion. The engine must be stopped and smoking is not allowed.
Do not overfill the tank, since the fuel may expand, and close the fuel filler cap properly.
Only use fuel recommended in the service literature. Fuel of an incorrect grade may cause malfunctions or stoppage by interfering with the operation of the fuel injection pump and the injectors.
This could cause engine damage and possibly personal injury.
Harmful gases
Only start the engine in a properly ventilated area. The exhaust emissions contain carbon monoxide and nitrogen oxides that are toxic.
When operating the engine in an enclosed area, an effective extraction device for exhaust gases and crankcase gases must be used.
Starter lock
If the control panel is not fitted with a key switch, the engine bay should be fitted with a lock to prevent unauthorized starting of the engine.
Alternatively, a lockable main switch or battery master switch may be used.
Starting spray
Never use starting spray or similar as a starting aid. An explosion may occur in the intake pipe, which could cause personal injury.
Operation
The engine should not be operated in environments with surrounding explosive materials since electrical or mechanical components of the engine may emit sparks.
It is always a safety hazard to be near an engine that is running. Body parts or clothing, or a dropped tool may get stuck in rotating parts, such as the fan, causing bodily injury.
Always cover rotating parts and hot surfaces as much as possible to ensure personal safety.

Safety precautions for handling materials
Fuel and lubrication oil
All fuels and lubricants as well as many chemicals are flammable. Always follow the instructions stated on the container.
All work on the fuel system must be performed when the engine is cold. Fuel leakage and spillage on hot surfaces may cause fire.
Store drenched rags and other flammable materials in a safe way to avoid spontaneous combustion.
Batteries
Batteries, particularly when being recharged, emit highly flammable fumes that can explode. Do not smoke or let open flame or sparks come near the batteries or the battery compartment.
Incorrect connection of a battery cable or jump start cable may cause a spark, which in tun may cause the battery to explode.
Chemicals
Most chemicals, such as glycol, corrosion inhibitors, preservation oils, degreasers etc. are hazardous. Always follow the safety precautions stated on the container.
Some chemicals, e.g. preservative oil, are flammable.
Always store chemicals and other hazardous materials in approved and distinctly marked containers and out of reach of unauthorized persons. Always dispose of superfluous or used chemicals through an authorized waste disposal contractor.
Safety precautions for care and maintenance
Stop the engine
Always stop the engine before any maintenance and service work unless otherwise stated.
Prevent unauthorized starting by removing the starter key and turning off the power by the main switch or the battery disconnect switch, locking it in the off position. Also attach a warning tag, stating that work on the engine is in progress, at a suitable location.
It is always a safety hazard to work on an engine that is running. Parts of your body or clothing, or a dropped tool may get stuck in rotating parts, causing bodily injury.
Hot surfaces and fluids
A hot engine always presents a risk of scalding. Always take care not to touch the exhaust manifold, turbocharger, oil pan, hot coolant and oil in pipes and hoses.
Lifting the engine
Use the engine lifting eyes when lifting the engine. First check that the lifting equipment is in proper condition and has sufficient lift capacity rating.
Auxiliary equipment fitted to the engine may cause the centre of gravity to be displaced. Thus, additional lift devices may be required in order to provide proper balance and a safe lift.
Never work below a suspended engine!
Batteries
Batteries contain a highly corrosive electrolyte (sulphuric acid). Always take care to protect your eyes, skin and clothing when charging and handling batteries. Wear protective gloves and goggles.
If electrolyte splashes on the skin, wash the affected part of the body with soap and plenty of water. If electrolyte splashes into the eyes, rinse eyes immediately with plenty of water and seek medical attention.
Dispose of used batteries through an authorized waste disposal contractor.

Electrical system
Before work is performed on the electrical system, turn off the power by the main switch or the battery disconnect switch.
Also disconnect any external power supply to auxiliary equipment on the engine.
Arc Welding
Before welding near or on the engine, remove the battery and alternator cables. Also remove the control unit connector.
Connect the weld clamp to the component to be welded, close to the weld location. Never connect it to the engine or in such a way that the current can pass through a bearing.
After the welding is completed, connect the cables to the alternator and the control unit before connecting the batteries.
Lubrication system
Hot oil may cause scalding and skin irritation. Avoid skin contact with hot oil.
Make sure that the pressure in the lubrication system is relieved before work is carried out. Never start or operate the engine with the oil filler cap removed since oil will be ejected forcefully.
Dispose of used oil through an authorized waste disposal contractor.
Cooling system
Never open the coolant filler cap while the engine is hot. Steam and hot coolant can come out forcefully and cause scalding.
If the cooling system must still opened or disassembled while the engine is hot, open the filler cap very cautiously and slowly to release the pressure before the cap is removed. Use gloves since the coolant is still very hot.
Dispose of used coolant through an authorized waste disposal contractor.
Fuel system
Always use gloves when checking for leaks in or performing other work on the fuel system. Always wear eye protection when testing injectors.
Fuel escaping under high pressure can penetrate body tissue and cause serious injury.
Never use non-genuine parts in the fuel system and the electrical system. Genuine parts are designed and manufactured to minimize fire and explosion hazard.
Before starting
Install any guards that have been removed before the engine is started. Check to ensure that no tools or other objects have been left on the engine.
Never start the engine unless the air filter is installed. Otherwise there is a risk of objects entering the compressor wheel or a risk of personal injury from contact with it.

DEC2 CONTROL SYSTEM
This engine has an injection pump with an electromagnetic actuator which adjusts the control rack to give the correct amount of fuel.
The system which controls the pump is called DEC2 (Digital Engine Control, generation 2).
The control unit (DEC2) continuously receives signals from sensors for engine speed, charge air temperature and pressure, coolant temperature, oil pressure, throttle position and control rack travel in the injection pump. Using this input data and a control program, the correct amount of fuel for the current operating conditions can be calculated.
The system’s sensors may be used only for DEC2, not for other instruments or other monitoring purposes.
The control unit contains monitoring functions to protect the engine in the event of a fault which would otherwise damage it. Faults and the more important monitoring functions are indicated on the control unit in the form of light emitting diodes. See illustration on page 14 for a description.
In case of a fault, the Power - or Shutdown indicator on the DEC2 control unit as well as the main indicator lamp on the main supply box and the instrument panel will illuminate.
If a fault has been indicated on the main indicator lamp the operator can determine the cause of the fault with the help of the LEDs on the control unit and the troubleshooting schedule on page 17, and carry out the required investigation and remedy.
Depending on the nature of the fault, the control system will take different actions to protect the engine such as reducing the power output, keeping the engine running at a constant low speed or, in case of a function impairing fault, shutting down the engine (Shutdown).
To enable readout of LED fault codes there is a lamp test/fault code switch located in the main supply box near the control unit.
A PC based program is also available to help service personnel to detect and rectify faults and to adjust certain parameters in the operating program.
Diagnostics and changes to programs must only be performed by authorized personnel.
The locations of the sensors and monitors that send signals to the control unit are shown in the illustrations on pages 13.
There is a description of the functions of the LEDs during normal operation on page 14.
On page 15 there is a description of the functions of the LEDs in case of a fault and actions in case of Power- and Shutdown indication.
Troubleshooting and fault code reading are described on pages 16 and 17.

LED functions during normal operation
Note: The lamp test/fault code switch should not be depressed. All LEDs come on briefly when the control unit is powered up.
CONTROL STATUS
The LED flashes continuously when the control unit is supplied with current, regardless of whether the engine is running or not.
SHUTDOWN
The LED is out.
STARTING
The LED lights up as soon as the engine turns over on cranking and follows the programmed starting sequence until it has been completed and then goes out.
RUNNING
The LED comes on when the engine has started and the "Starting" LED goes out. It remains on until the engine is stopped.
TORQUE LIMIT
The LED comes on when the control unit detects that the engine has received the maximum permissible quantity of injected fuel according to its power curve. This means 100% power output at the current rpm. If the load increases, engine rpm will decrease.
BOOST LIMIT
The LED comes on when the control unit smoke limiter restricts the maximum fuel quantity. Operation of the smoke limiter is dependent on the charge air pressure.
POWER-
The LED remains out during normal operation as long as no fault is detected by the control unit. See next page for the procedure to be adopted in the event of a fault.
POWER+
If the control unit is programmed to allow the engine to be operated according to more than one power/torque curve (map), the following applies.
The LED comes on when the engine is run at more than 100% power output (MAP 2). It goes out when the engine returns to the 100% power output curve (MAP 1) or when the power output required is less than 100%.

Action in case of a fault
LED indications in case of a fault
Note The main indicator lamp in the main supply box and at the instrument panel has indicated a fault. The lamp test/fault code switch should not be depressed.
CONTROL STATUS
The LED will continue to flash even in case of a fault as long as voltage is supplied to the control unit.
POWER -
If the LED comes on, the control unit has detected a defect that could cause damage to the engine if operation continues.
The control unit automatically reduces engine power output to a predefined level if the corresponding function has been selected.
Action: Reduce engine speed to idle if possible and conduct troubleshooting according to instructions on page 16 and the chart on page 17
SHUTDOWN
The LED comes on and the engine is switched off automatically in case of a severe fault that could cause damage to the engine if operation continues.
Action: Conduct troubleshooting according to instructions on page 16 and the chart on page 17
If the engine has not stopped, reduce engine speed to idle and conduct troubleshooting.

Changing functions using the DIP switches in the control unit
There are 8 DIP switches in the control unit under the round black rubber cover.
These switches shall be in the ON position to obtain normal functions according to the operating program. However, for single-speed engines, the normal position of DIP switches 6, 7, and 8 may also be OFF
Shutdown at threshold values for low oil pressure and high coolant temperature can be selected by setting DIP switch 4 to OFF
With DIP switch 4 in position ON, Power- indication is obtained for these threshold values. Engine output reduction (LOP) can be selected to prevent damage to the engine. Changes to the program must only be performed by authorized personnel.
Note Do not operate the engine with a Power- indication except for in emergencies.
The DIP switches are showed in ON position
Readout of fault codes
Note If the engine has stopped or lost power but the main indicator lamp is out and neither POWERnor SHUTDOWN are on, the fault is outside the control unit detection range. Probable causes: fuel shortage, temporary overload, mechanical fault.
-Activate the lamp test/fault code switch. In Scania electrical equipment the main indicator lamp is located in this switch on the main supply box.
-All LEDs will then come on for 2 seconds to indicate that they are intact and in working order. This also applies to the main indicator lamp in the main supply box and the instrument panel. Make a note of any LED that is defective.
-All LEDs will then be out for approximately 4 seconds.
-Following this, a fault code will be indicated on one of the LEDs for 2 seconds. Note which LED it is.
-The control unit then resumes the operating mode automatically.
-After having made a note of the fault code, reset the lamp test/fault code switch and reset the control unit by turning off its power supply momentarily.
-The most probable cause of the fault can then be found in the trouble shooting schedule on the next page.
-When the fault or faults have been rectified the engine can be restarted.
-If the control system continues to indicate a fault by way of the main indicator lamp, further faults may have been recorded. The fault code readout must then be repeated as per above since the system can only display one fault code at a time.
