Special instructions for work on the common rail system

• Do not touch live parts on the electrical connection of the injectors when the diesel engine is running.

3. Modern components of the diesel injection today consist of highly precise parts that are subjected to extreme loads. Due to this high precision technology, the utmost cleanliness is to be ensured during all work on the fuel system. Even particles of dirt larger than 0.2 mm can lead to failure of components.

4. Therefore, before starting the work, the subsequently described measures are to be followed atallcosts:

• Before work on the clean side of the fuel system, the diesel engine and the must be closed while doing so.

• Perform a visual inspection for leaks or damage to the fuel system.

• Do not spray the steam jet directly at electrical parts, or attach covers.

• Bring the diesel engine into a clean area of the workshop, in which no work is being performed that could cause dust to be dispersed (grinding, welding work, brake repairs, brake and power tests etc.).

• Avoid air movements (possible dust turbulence through starting the diesel engines, the workshop ventilation or heating system, through drafts, etc.).

• The area of the fuel system still closed is to be cleaned and dried using compressed air.

• Removeloosedirtparticles,suchaspaintchippingsandinsulatingmaterials, with a suitable suction device (industrial vacuum cleaner).

• Hang a new and clean protective sheet over areas of the diesel engine compartment from which dirt particles could come loose.

• Before starting dismantling work, hands must be washed and clean work clothes must be put on.

5. When performing the work, the subsequently described measures are to be followed atallcosts:

• After opening the clean side fuel system, the use of compressed air for cleaning is not permitted.

• Loosedirtistoberemovedduringtheassemblyworkusingasuitablesuction device (industrial vacuum cleaner).

•Only lint-free cleaning cloths may be used on the fuel system.

• Tools and work equipment must be cleaned before starting the work.

• Only tools that have no damage (cracked chrome coatings) may be used.

• When removing and installing components, no materials such as cloths, cardboard or wood may be used since these can deposit particles and

• If paint chippings arise when unfastening connections (due to possible overcoating), these paint chips are to be carefully removed

• All parts removed from the clean side fuel system are to be immediately closed at their connection opening with appropriate sealing caps.

• Thissealingmaterialmustbepackeddust-tightuntiluseandistobedisposed after one-time use.

• Then all parts are to be carefully stored in a clean, sealed container.

• Never use used cleaning or test liquids for these parts.

• New parts may only be removed from the original packaging immediately before use.

• Work on removed components may only be performed at a work station equipped for this.

• If removed parts are being shipped, always use the original packaging for the new part.

1. Riskofinjurythroughmovingparts

Rotating and/or linear moving parts can cause serious injuries.

• Do not reach into moving parts or handle moving parts during operation.

• Do not open covers during operation.

• Note the follow-up time: Before opening the covers, make sure that no parts are still moving.

•

2. Riskofdeaththroughfallingload

Loads can fall down during lifting procedures. This can cause serious injuries up to and including death.

• Use the transport devices only for transporting the engine without additional attachments.

• Diagonal pulling is not permitted, therefore use a suspension device.

3. serious or fatal injuries.

• Do not smoke inside the danger zone and in the immediate surroundings.

•

• Report suspicious substances, liquids or gases immediately to those responsible.

• all-clear signal is given.

4. Riskofinjuryduetohazardouscoolants lead to serious poisoning, allergies, skin irritations and eye damage.

• Observe safety sheets of the manufacturer.

• Always wear protective work clothes, chemical-resistant protective gloves

• Avoid spillage and fog formation.

5. burns upon contact.

•

6. Riskofburnsduetohotsurfaces

Contact with hot parts can cause burns.

• Always wear protective work clothes and protective gloves for all work near hot parts.

• Make sure that parts have cooled down to the ambient temperature before all work.

7. Hearingdamageduetonoise

Exhaust aftertreatment system (SCR)

The noise level occurring in the work area can cause serious hearing damage.

• Always wear hearing protective when working.

• Only reside in the danger zone where required.

8. Riskofinjuryonedgesandcorners

Sharp edges and pointed corners can cause abrasions and cuts to the skin.

• Always proceed with caution when working near sharp edges and pointed corners.

• When in doubt, wear protective gloves

9. Riskoftrippingduetodirtandobjectslyingaround

Dirt and objects lying around can lead to slipping and tripping and cause

• Always keep the work area clean.

• Remove objects that are no longer needed.

• Mark tripping hazards with yellow and black tape.
