12.5 Recycling
Due to the high metal content, hydraulic products can mostly be recycled. In order to
achieve an ideal metal recovery, disassembly into individual assemblies is required.
The metals contained in electric and electronic assemblies can be recovered by
means of special separation procedures as well.

14 Troubleshooting
14.1 How to proceed for troubleshooting
▶
Always work systematically and purposefully, even when under time pressure.
In the worst case, random, thoughtless disassembly and changing settings might
result in the inability to identify the original cause of error.
▶
First, get an overview of the functions of the valve in conjunction with the overall
system.
▶
Try to find out whether the valve has worked properly in conjunction with the
overall system before the error occurred.
▶
Try to determine any changes to the overall system in which the valve is integrated:
– Were there any changes to the application conditions or area of application of
the valve?
– Have changes (e.g. refitting) or repair work been carried out on the overall
system (machine/system, electrical systems, control) or at the valve? If so:
What were they?
– Was the valve and/or the machine used as intended?
– How did the fault become apparent?
▶
Try to get a clear idea of the cause of error. Ask the direct (machine) operator.
