- The determined operating pressure may not be exceeded.
- Tensile load and torsion to the hoses must be avoided (see fi gure 2, item 1). 1).
- Do not kink the hoses (see fi gure 2, item 2). 2).
- Do not drag or lay hoses across sharp edges (see fi gure 2, item 3). 3).
- Do not connect twisted hoses (see fi gure 2, item 4). 4).
- Never drive over the hoses with a motorised vehicle. Hoses laid loosely across roads or
paths are to be protected from damage e.g. by hose protection ramps (see fi gure 2, item 5).
- In the event of high external temperatures, the hoses are to be installed either at an
adequate distance from the heat-radiating components or are to be protected by suitable
measures (see fi gure 2, item 6).
- Do not hang any weights on the hoses.
3.1 Advices for hoses
Hoses must be laid or secured such that, in the event of a failure of the hose, danger is
avoided as far as possible.
Danger can be caused by:
- The hose thrashing about following a tear caused by external infl uences, for example.
- The pressure media leaking under pressure,
- The lighting of leaking pressure media within the vicinity of an ignition source.
The danger can be avoided by means of protective coverings or screening, for example.
- Even when stored correctly and used properly, hoses are subject to a natural ageing
process. This means that their period of storage and period of use are restricted.
The following is to be observed when storing the hoses:
- Store in a cool, dry and low-dust condition (possibly wrap in plastic fi lm). Avoid direct
sunlight and UV rays. Screen from heat sources in the vicinity.
- Do not use any ozone-forming lighting fi xtures such as fl uorescent light sources,
mercury vapour lamps) or electrical equipment close to the equipment.
- Store hoses such that they are stress-free in a fl at position. If storing in rings, the
smallest bending radius stated by the manufacturer may not be exceeded.
WARNING / CAUTION for hairline cracks!
- Leaking hydraulic fl uid under high-pressure can cause serious injuries to the
skin.
- In the event of injuries, immediately consult a doctor!
Hydraulic
fl uid must immediately be removed from wounds!
- Do not use your fi ngers to detect leaks!
- Relieve the hydraulic system before you loosen connections!
