12.8.1 Labelling hydraulic hose lines
The assembly labelling provides the follow-
ing information:
Fig. 137/...
(1) Manufacturer's marking on the hydraulic
hose line (A1HF)
(2) Date of manufacture of hydraulic hose line
(04 / 02 = year / month = February 2004)
(3) Maximum approved operating pressure
(210 BAR).

12.8.2 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. Replace any worn or damaged hydraulic hose lines immediately.
12.8.3 Inspection criteria for hydraulic hose lines
For your own safety, comply with the following 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 mate-
rial).
• 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).
• Untight 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 fitting is "2004", then the hose should not be
used beyond February 2010. See also "Labelling of hydraulic
hose lines".
