Cleaning, maintenance and repairs
13.5.1 Labelling of hydraulic hose lines
Valve chest identification provides the follow-
ing information:
Fig. 144/...
(1) Manufacturer's mark on the hydraulic hose
lines (A1HF)
(2) Date of manufacture of the hydraulic hose
lines (02 04 = February 2004)
(3) Maximum approved operating pressure
(210 BAR).

13.5.2 Maintenance intervals
After the first 10 operating hours, and then every
50 operating hours
1. Check all the components of the hydraulic system for tightness.
2. If necessary, tighten screw unions.
Before each start-up:
1. Check hydraulic hose lines for visible damage.
2. Eliminate any scouring points on hydraulic hose lines and pipes.
3. Immediately replace worn or damaged hydraulic hose lines.
13.5.3 Inspection criteria for hydraulic hose lines
For your own safety and in order to reduce pollution, ensure the fol-
lowing inspection criteria.
Replace hoses if the respective hose fulfils at least one of the follow-
ing criteria:
•
Damage to the outer layer up to the ply (e.g. scouring points,
cuts, cracks).
•
Brittleness of the outer layer (crack formation of the hose materi-
al).
•
Deformations which do not match the natural shape of the hose.
Both in a depressurised and pressurised state or when bent (e.g.
layer separation, bubble formation, pinching, bends).
•
Leak points.
•
Installation requirements not complied with.
•
Life span of 6 years has been exceeded.
The date of manufacture of the hydraulic hose line on the as-
sembly is decisive for determining these six years. If the date of
manufacture on the assembly is "2004", then the hose should
not be used beyond February 2010. See also "Labelling of hy-
draulic hose lines".
