13 Troubleshooting

13.1 How to proceed for troubleshooting

• Always work systematically and targeted, even when under time pressure. Random,
thoughtless disassembly and changing of settings can, in the worst-case-scenario,
result in the inability to determine the original error cause.
• First get a general idea of how your product works in conjunction with the over-
all system.
• Try to find out whether the product has worked properly in conjunction with the
overall system before the error occurred first.
• Try to determine any changes of the overall system in which the product is integrated:
– Were there any changes to the product's application conditions or area of application?
– Were there any changes (e. g. refittings) or have repairs been carried out at the
overall system (machine/system, electrical systems, control) or at the product?
If so: What were they?
– Was the product or machine used as intended?
– How did the fault become apparent?
– Try to get a clear idea of the cause of the error. Ask the direct (machine) operator.
– If you could not remedy the occurred error, please contact one of the addresses
you find at www.boschrexroth.com or in the list of addresses in the appendix.
