For hydraulic fluid change, proceed as follows:
▶
Fully drain the hydraulic fluid, see also chapter 11.1 “Preparing for
decommissioning“ on page 58.
▶
In this connection, ensure complete draining of the lines and actuators.
▶
If required, bleed the hydraulic system.
▶
Fill the hydraulic system as for first filling and then bleed it, see chapter 8.1.2
“Filling the hydraulic system“ on page 48.
10.5.8 Visual inspection for leakage, cracking, force effects and corrosion
The external inspection is a visual inspection and needs to be carried out at least
semi-annually (or more often depending on operating conditions and use).
Clean the system before visual inspection as necessary.
Visual inspection is carried out for:
• Leakage
• Cracking
• Corrosion
• Dents due to external force effects
In case of leakage at screwed-in components, document the leakage and re-tighten
the components. If leakage still occurs at this position, the contact must be
thoroughly checked for the cause of leakage. Depending on the result, seals and/or
the component must be replaced.
In case of cracking and resulting leakage, the cause must be identified and
corrected. Afterwards, affected components must be replaced or thoroughly
repaired.
In case of indications of external force effects, the cause must be identified and
corrected. Afterwards, the component and enclosing components must be checked
for damage and assessed for further reliable use.
As required, these components are to be replaced or thoroughly repaired.
In case of indications of corrosion, the component must be checked for damage and
assessed for further reliable use. As required, this component is to be replaced or
professionally repaired. In any case, corrosion protection must be ensured.
10.5.9 Checking the heat exchanger
The heat exchanger does not require specific maintenance. The set-up of the heat
exchanger is robust and does not lead to any increased requirements for the cooling
water unit. Dirt particles must not exceed 1 mm.
