Fig. 28: Example
Notes and measures to be applied
before starting work in the fuel
system
General – Maintenance and repair
n
Bleed the hydraulic circuits.
n
Start up the hydraulic system without load.
n
Check the hydraulic oil level in the tank, if necessary top up
with hydraulic oil as specified in the operating and maintenance
instructions or drain oil off into a suitable container.
n
Check fittings and flanges for leaks.
n
After each repair check all adjustment data, system pressures,
rotational speeds and nominal values in the hydraulic system,
adjust if necessary.
n
Do not adjust pressure relief valves and control valves to
values above their specified values.
Special requirements with respect to cleanliness in the fuel system
do apply for commissioning, maintenance and repair work, particu-
larly for engines with the Common Rail System. Contamination like
dirt, welding residues or similar can lead to the failure of individual
components and adversely affect engine operation.
Spare parts should be left in their original packaging as long as
possible and should only be unpacked just before use.
When parts are unpacked any connections must be closed with
suitable plugs or caps, in order to prevent contamination of hose
connections. If e.g. fuel hoses are connected to one side, while the
second side cannot yet be connected, there is a danger of dirt
entering into the system. The free connection must in this case
also be appropriately closed.
n
The fuel system must be closed. Visual examination for leaks /
damage in the fuel system.
n
Before starting work in the fuel system clean the complete
engine and the engine compartment with the system still
closed.
n
The engine should be dry before work is started in the fuel
system.
n
Blow drying with compressed air is only permitted while the fuel
system is still closed.
