5.1 Handling of hoses
- never exceed the permissible working pressure as stated on hose and/or literature
- avoid any tension (see figure 1) and do not hang any load onto the hose
- never exceed the minimum bend radius as resulting kink will cause failure of hose (see figure
2)
- do not allow hose to contact sharp edges or rough objects (see figure 3)
- avoid any twisting of hose (see figure 4)
- do not run over hose with any vehicle or equipment ! Hoses which are put on the surface of
sidewalk or street have to be suitably protected (see figure 5)
- do not allow hose to contact areas of high temperature such as mufflers, exhaust manifold,
heaters or burners. Protect the hose as shown in figure 6 or install it in sufficient distance
from the source of heat.
- it is not allowed to attach weights to the hoses
- make sure that no objects fall on the hoses.
5.2 Protection of the working area in case of breakdown of hoses
Hoses have to be installed or protected in such a way that dangers are prevented, if possible, in
case of breakdown of the hoses.
Danger can be caused by:
-
Uncontrolled hose movement after a hose rupture caused e.g. by external influence.
- Emerging of the pressure medium under pressure.
- Inflammation of pressure medium near igniting sources
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.
