14.2.1 Identification of hydraulic hoses
The identification on the fittings of a hydraulic hose provides the following information:
1) Identification of the hydraulic hose manufacturer (A1HF)
2) Manufacturing date of the hydraulic hose (02 10 = February 2010)
3) Maximum permissible operating pressure (210 BAR).
14.2.2 Maintenance intervals
After the first 10 operating hours and then every 50 operating hours
1. Check all components in the hydraulic system for leaks.
2. Retighten screw fittings, if necessary.
Before each start-up
1. Check hydraulic hoses for apparent faults.
2. Remedy chafed sections on hydraulic hoses and pipes.
3. Immediately replace worn or damaged hydraulic hoses and pipes.
14.2.3 Inspection criteria for hydraulic hoses
For your own safety and to reduce any possible environmental impact pay attention to the following
inspection criteria!
Replace hoses, if these fulfil at least one criterion from the following list:
• Damage to the outer layer to to the ply (e.g. chafing, cuts, cracks).
• Embrittlement of the outer layer (formation of cracks in the hose material).
• Deformations, which do not correspond with the natural shape of the hose. Both in pressure-
less and pressurized condition or in case of bending (e.g. layer separation, formation of blisters,
squeezing, buckling).
• Leakages.
• Failure to comply with installation requirements.
• The max. utilization period of 6 years has expired. The date of manufacture on the hydraulic hose
fitting plus 6 years is decisive. If the fitting is marked with the manufacturing date "2010", the utili -
zation period ends in February 2016.
See also "Identification of hydraulic hoses".
Leaking hoses / pipes are frequently the result of:
• missing O-rings or seals
•
damaged or poorly fitted O-rings
• brittle or deformed O-rings or seals
• foreign objects
• loose hose clamps
14.2.4 Assembly and disassembly of hydraulic hoses
Use
• only original spare hoses from HORSCH LEEB AS. These spare hoses withstand the chemical, mechanical
and thermal loads.
• only hose clamps made of V2A when installing hoses.
