6.6.1 Marking of hydraulic hose lines
The marking on the valve (Fig. 6.13) provides
the following information:
(1) Mark of the manufacturer of the hydraulic
hose line (A1HF)
(2) Manufacture date of the hydraulic hose line
(04 / 02 = year / month = Feb. 2004).
(3) Maximum operating pressure (210 BAR)

6.6.2 Servicing intervals
After the first 10 operating hours and then every 50
operating hours.
1. Check all components of the hydraulic system for leaks.
2. If necessary, retighten the screw connections.
Before every start-up:
1. Check the hydraulic hose lines for obvious defects.
2. Correct any worn areas on hydraulic lines and pipes.
3. Immediately replace worn or damaged hydraulic hose lines.
6.6.3 Inspection criteria for hydraulic hose lines
For your own safety:
Replace hydraulic hose lines immediately you observe one of the
following defects:
•
Damage to the outer layer down to the reinforcement (e.g. from
rubbing points, cuts, tears).
•
Brittleness of the outer layer (recognisable by crack formation of
the hose material).
•
Unnatural deformations of the hydraulic hose lines, e.g. layer
separation, bubble formations, areas of crushing or kinking.
•
Leaks.
•
Damage, deformation or leaks of the hose fittings. Slight surface
damage is not grounds for replacement.
•
Detachment of the hose from the fittings.
•
Corrosion of the valve/fitting that can impair its function and
strength.
•
Unprofessionally laid hydraulic hose lines, e.g. bending radii not
adhered to, positioning over sharp edges.
