5.1 Handling instructions for hose lines
- The defined operating pressure must not be exceeded.
- The hoses must not be subjected to tension and torsion (see picture 2, fig. 1).
- The hose line must not be bent (see picture 2, fig. 2).
- Do not pull or lay hoses across edges (see picture 2, fig. 3).
- Do not connect twisted hoses (see picture 2, fig. 4).
- Never drive a vehicle over the hoses. Loose hose lines laid on roads and paths
must be protected against damage, e.g. with hose bridges (see picture 2, fig. 5).
- In the event of high temperatures occurring externally, the hose lines must either
be fitted a sufficient distance from the heat-emitting components or protected by
suitable measures (shields) (see picture 2, fig. 6).
- Weights must not be suspended on the hose lines.
- Objects must not be allowed to fall onto the hose lines.
5.2 Securing the environment in the event of a hose failing
Hose lines must be laid or secured such that risk of the hose failing is avoided.
Danger can occur as a result of:
-
the hose moving back and forth after tearing, e.g. through external influence,
- the pressure medium escaping under pressure,
- escaping pressure medium igniting close to a igniting source.
The danger can be avoided, for example, with protective coverings or shields.
5.2.1 Beware of hairline tears
-
Escaping high-pressure oil can cause serious injuries
when impinge to the skin.
- In the event of an injury, immediately consult a doctor!
- Oil must immediately be cleaned from the wound.
- Do not search for leaks using a finger.
- Depressurise the hydraulic system before loosening
connections.
5.3 Storing hose lines
- Hose lines are subject to natural aging even when stores correctly and with
permissible loads. As a result, their storage time and period of use are limited.
When storing hose lines, the following should be observed:
-
Store cool, dry and dust-free (ideally, wrapped in plastic); avoid direct sunlight or
UV radiation; shield from nearby sources of heat.
- Do not use ozone-forming lights (e.g. fluorescent lights, mercury vapour lamps)
or electrical devices in the immediate surroundings
- Hose lines must be stored de-energised and in a lying position. If storing in
rings, the smallest bend radius as recommended by the manufacturer, must not
be exceeded.
5.4 Labelling the hose lines
- The hose is labelled with manufacturer and operating pressure.
- The maximum permissible operating pressure and month./year of manufacture
are labelled at the pressurised neck.
