Rules for cleanliness
When working on fuel supply and injection system, pay careful
attention to the following “rules” for cleanliness:
◆
Thoroughly clean all unions and surrounding areas before
disconnecting.
◆
Place removed parts on a clean surface and cover. Use only
lint-free cloths.
◆
Carefully cover opened components or seal if repairs cannot
be carried out immediately.
◆
Install clean components only. Do not remove replacement
parts from packing until immediately before installing. Do not
use parts that have not been stored in their packing (e.g. in
tool boxes etc.).
◆
Existing transport and protective packaging and sealing caps
must only be removed immediately prior to installation.
◆
When system is open: do not work with compressed air if
this can be avoided. Do not move vehicle/machine unless
absolutely necessary.
◆
Also ensure that no diesel fuel comes into contact with the
coolant hoses. Should this occur, the hoses must be cleaned
immediately. Damaged hoses must be renewed.
