2.8.3 Cleanliness standards and safety
NOTICE
Property damage due to neglect of cleanliness standards!
Modern components, especially the injection system, consist of high precision parts that are
subject to extreme loading.
Dirt particles of 20 µm (0.79 th) or greater can result in component outages. Due to this high
precision engineering, maintain a high standard of cleanliness for all tasks.
Before and while performing any task, observe the following precautions:
u Ensure a clean area, free of stirred up dust by air movements.
u Perform visual inspections for leaks or damage.
u Before starting any task on the closed fuel system, clean the engine and its compartment
with lint free tissue.
u Ensure waterproof covers are on the electrical components.
u Do not direct steam jet at electrical components or their covers.
u Clean and dry the area around the still closed fuel system with compressed air.
u Remove loose dirt particles such as paint chips and insulation material with suitable equip‐
ment.
u Cover the areas of the engine compartment which could produce dirt particles with a new
and clean covering film.
u Before beginning the dismantling work, wash hands and put on fresh personal protective
equipment.
u Clean tools and working materials.
u Perform work on components at a suitably equipped workplace.
u Use only undamaged tools.
u After opening the fuel system, the use of compressed air for cleaning is prohibited.
u Remove any loose dirt during installation work with suitable equipment.
u Remove any paint chips before loosening or tightening any connections.
u Use only lint-free cleaning tissues.
u Use particle and fiber-free materials.
u Immediately seal the opened connection with sealing caps.
u Keep the sealing material in dust-free packaging until use and dispose of it after single use.
u Place the components into a clean, sealed container.
u Never use contaminated cleaning or testing fluids.
u Remove new components from the original packaging immediately before use.
u Use the original packaging of the new parts to ship removed parts.
