The assembly labeling provides the following
information:
Fig. 69/...
(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
(3,045 psi [210 BAR]).

12.12.2 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 locking bolt.
Before each start-up:
1. Check hydraulic hose lines for visible damage.
2. Eliminate any rubbing points on hydraulic hose lines and pipes.
3. Replace any worn or damaged hydraulic hose lines immediately.
12.12.3 Inspection criteria for hydraulic hose lines
For your own safety, comply with the following inspection criteria!
Replace hydraulic hose lines upon discovering any of the follow-
ing during inspection:
•
damage to the outer layer up to the ply (e.g. rubbing points, cuts,
and cracks)
•
brittleness of outer layer (crack formation of the hose material)
•
deformations which do not match the natural shape of the hose
or the hose line. Both in a depressurized and pressurized state
or when bent (e.g. layer separation, bubble formation, pinching,
bends)
•
leakage points
•
damages or deformations of hose fittings (sealing function re-
stricted); minor surface damage is not a reason for replacement
•
movement of the hose out of the fitting
•
corrosion of the fitting, reducing the function and tightness
•
installation requirements not complied with
•
life span of 6 years has been exceeded
