Blow drying with compressed air is only permitted
l
while the fuel system is still closed.
When using steam cleaning equipment cover con-
l
trol unit, cable plugs, all other electrical connections
and the generator beforehand and do not expose
these items to the direct steam jet.
Electrical plug connections must be plugged in dur-
l
ing jet cleaning.
Remove loose parts (e.g. paint scales that may
l
have come off during assembly work) with an indus-
trial vacuum cleaner or any means of extraction.
Vacuum cleaning equipment must generally be
l
used for cleaning when the fuel system is open.
Perform work on the fuel system only in a clean en-
l
vironment (no dust, no grinding or welding work).
Avoid draughts (dust). The workshop floor must be
cleaned at regular intervals. No brake or power test
stand should be present or operated in the same
room.
Air movements, which could swirl up dust, such as
l
brake repairs or starting of engines, must be strictly
avoided.
For work, such as disassembly and assembly of de-
l
fective hydraulic components in the Common Rail
System, it is strongly recommended to set up a sep-
arate workshop area, i.e. an area which is spatially
separated from all other areas (general vehicle re-
pairs, brake repairs).
No general machine tools should be operated in this
l
room.
Periodic cleaning of this workshop area is obligato-
l
ry, draughts, ventilation system and heating blow-
ers must be minimized.
Engine compartment area where dirt particles could
l
come loose, should be covered with new, clean foil.
Working means and tools must be cleaned before
l
being used for work. Use only tools without dam-
aged chromium coating, or tools without chromium
coating.
Notes and measures to be applied during work in
the fuel system
Wear clean working clothes.
l
Use only lint-free cleaning cloths for work in the fuel
l
system.
Remove loose parts (e.g. paint scales that may
l
have come off during assembly work) with an indus-
trial vacuum cleaner or any means of extraction.
Vacuum cleaning equipment must generally be
used for cleaning when the fuel system is open.
Working means and tools must be cleaned before
l
being used for work. Use only tools without dam-
aged chromium coating, or tools without chromium
coating.
22
Do not use any previously used cleaning or testing
l
fluids for cleaning.
Compressed air should never be used for cleaning
l
when the fuel system is open.
Work on disassembled components must only be
l
carried out at a specially furnished work place.
When disassembling or assembling components
l
you should not use any materials from which parti-
cles or fibres could flake off (cardboard, wood, tow-
els).
Dismantled parts must only be wiped off with clean,
l
lint-free cloths if required. No dirt particles must be
wiped into the components.
Close openings on components and engine imme-
l
diately with suitable plugs/caps.
Plugs/caps must only be removed just before the in-
l
stallation.
Keep plugs/caps in their original packaging, where
l
they are protected against dust and dirt, dispose of
after one time use.
Take new parts out of their original packaging just
l
before installation.
Disassembled components must be stored in new,
l
sealable bags or – if available – in the packaging
material of the new components.
Always use the original packaging material of the
l
new part to return the disassembled old component.
Notes and measures concerning the workshop
area
For work, such as disassembly and assembly of de-
l
fective hydraulic components in the Common Rail
System, it is strongly recommended to set up a sep-
arate workshop area, i.e. an area which is spatially
separated from all other areas (general vehicle re-
pairs, brake repairs).
The workshop floor must be sealed or tiled.
l
No welding equipment, grinding machines, general
l
machine tools, brake or power test benches must
be operated in this room.
Periodic cleaning of this workshop area is obligato-
l
ry, draughts, ventilation system and heating blow-
ers must be minimized.
Notes and measures for work place and tools in
the workshop
A special work place must be set up for work on dis-
l
assembled components.
Clean disassembly and assembly tools at regular
l
intervals and keep these in a closed tool cabinet.
