6.6.1 Labelling of hydraulic lines
The labelling on the valve (Fig. ) provides the
following information:
(1) Manufacturer's labelling of the hydraulic line
(A1HF)
(2) Hydraulic line date of manufacture
(04 / 02 = year / month = April 2002)
(3) Maximum permissible operating pressure
(210 BAR)
Fig. 6.5
6.6.2 Maintenance intervals
After the first 10 operating hours and then every 50 operating
hours:
1. Check all hydraulic system components for tightness.
2. Re-tighten the screw connections if necessary.
Before each start-up:
1. Check the hydraulic lines for obvious defects.
2. Repair chafing points on the hydraulic lines and pipes.
3. Replace worn or damaged hydraulic lines immediately.
6.6.3 Inspection criteria for hydraulic lines
For your own safety:
Replace hydraulic lines immediately, as soon as one of the following
defects is noticed:
•
Damage to the outer layer up to the insert (e.g. chafing, cuts,
cracks).
•
Brittleness of the outer layer (visible due to cracks in the hose
material).
•
Unnatural deformation of the hydraulic line, e.g. delamination,
blistering, crushing or kinking.
•
Leakage.
•
Damage, deformation or leakage of the hose fitting. Minor surface
damage is no reason for replacement.
•
The hose slipping out of the valve.
•
Valve corrosion, which may diminish functionality and strength.
•
Improperly routed hydraulic lines, e.g. neglected bending radii,
routing across sharp edges.
