  • Page 257: Recurring Test

    T E S T I N G H O S E L I N E S Recurring test Since hose lines are subject to influences that cause damage during operation and can lead to dangerous situations, they must be tested recurrently at fixed intervals. The aim of recurring tests is to detect and repair damage in good time.

    T E S T I N G H O S E L I N E S Persons qualified to test hose lines A qualified person is a person who, through his or her professional training, professional experience and recent professional activity, has the necessary specialist knowledge required for testing work equipment - in this case for testing hose lines.

  • Page 259: Replacing Hose Lines

    M A I N E N T A N C E Auswechseln Replacing hose lines As a general rule, even when stored properly and subjected to permissible stress during use, all hose lines are subject to natural aging, which changes the material and composite properties and reduces the performance of the hose lines.

    S E R V I C E L I F E Service life of L&W high pressure hoses When determining the service life or the replacement interval of the individual hose lines, the concrete specifications and recommendations of the hose line or machine manufacturer must be observed. Furthermore, empirical values resulting from previous tests done under the prevailing operating conditions on site are also relevant.
