15.2 Hydraulic hygiene
Note:
Risk of malfunction.
If impurities get into the hydraulic system, there is a risk of malfunctions in
part or all of the hydraulic system. There is also a risk of severe damage to
components.
For all work on the hydraulic system, the following instructions must be
followed.
Note:
Use only new and clean oil when refilling the hydraulic oil system. If the oil is
contaminated, the hydraulic components will suffer damage.
15.2.1 Washing
Hydraulic components, including hydraulic hoses and pipes, must be cleaned
with a filtered washing fluid using a method suitable for the components
concerned.
The washing fluid must have purity code 19/16/13 in accordance with
ISO4406:1999 or 16/13 in accordance with ISO4406:1987.
Blowing clean with dry filtered air may be done when this is the only practical
method to carry out cleaning.
15.2.2 Packaging
After cleaning, all openings must be sealed with protective plugs. Connecting
surfaces must be protected against handling damage and dirt penetration.
Completely dry components can be packed in plastic bags or boxes with lids.
The packaging (protective plugs, masking, plastic bag, etc.) must not be
removed until immediately before the component is to be fitted in a workplace
suitable for handling hydraulic components.
Tape must never be used without cleaning afterwards.
Protective plugs must be stored in plastic bags or boxes with lids until they
are used.
After use, discard the plugs and plastic bags.
15.2.3 Handling
Hydraulic components must be handled and transported with the greatest
care.
Transportation packaging must be used throughout the entire handling chain.
This packaging must be clean and free from dust, etc.
