Dangers can be prevented by e.g. protective coverings or shieldings
5.2.1 Do not go near leaks!
- High pressure oil easily punctures skin causing serious injury,
gangrene or death!
- If injured, seek emergency medical help! Immediate surgery is
required to remove oil!
- Do not use finger or skin to check for leaks!
- Lower load or relieve hydraulic pressure befor loosening finttings!
5.3 Storage of hoses
- Hoses are subject to a natural aging even if they are stored correctly. Therefore, their
storage and service time is limited.
When storing the hoses please observe the following:
- Store them cool, dry and dustless (eventually wrapped with plastics sheeting); prevent direct
solar radiation and UV rays; shield heat sources which are near the hoses.
- Do not use any ozone producing lamps (e.g. fluorescent light sources, mercury-vapor lamp)
or electrical devices next to the hoses.
- Hoses have to be stored freely of tension and in a horizontal position. If they are stored in
rings the smallest bending radius determined by the manufacturer must not fall below.
5.4 Marking of hoses
- The hose is marked with the manufacturer's name and quarter/year of production.
- The max. allowable pressure and month/year of production is indicated on the hose end fitting.
5.5 Inspection and replacement intervals of hoses
- After each operation the hoses have to be checked for external damages, cracks,
kinks and bubbles!
- The operator has to replace the hoses in appropriate period of times, even if there are no
visible security defects on the hoses.
- The hoses have to be replaced 10 years as from date of manufacture at the latest
(see marking on the hose)!
Hoses are subject to a natural aging even if they are stored correctly. Therefore, their storage
and service time is limited.
- Hoses have to be checked by a skilled person before the first putting into operation
of the technical device and afterwards at least once a year for their safe working
condition.
A skilled person is somebody having sufficient knowledge concerning hydraulic hoses due to his
special training and knowledge. He/she must be acquainted with the local safety working
conditions, accident prevention regulations, technical regulations and approved standards (e.g.
DIN-Standards), so that he/she is capable to estimate the safety working conditions of the
hydraulic hoses.
