14 Troubleshooting
Table 13 can help you with troubleshooting This table is not exhaustive.
Issues may occur in practice that are not listed here.
Only authorized personnel may perform troubleshooting inside a safety area
designated by the machine manufacturer.
14.1 How to proceed with troubleshooting
▶ Perform troubleshooting if possible with reduced operating data (e.g., slowly
swinging in or out and slow pressure increases).
▶ Proceed in a systematic and purposeful manner, even when pressed for time.
The random and imprudent removal andchanging of settings could result in the
inability to ascertain the original cause of failure.
▶ First obtain a general overview of how your product functions in conjunction with
the overall system.
▶ Try to find out whether or not the product was working properly in conjunction
with the entire system before the fault occurred.
▶ Try to determine any changes to the entire system in which the product is installed:
– Were there any changes to the product's operating conditions or operating range?
– Has maintenance work recently been carried out? Is there an inspection or
maintenance log?
– Have any changes (e.g., upgrades) or repairs been made to the overall system
(machine/system, electrics, control) or to the product? If yes, which?
– Has the hydraulic fluid been changed?
– Has the product or machine been used as intended?
– How did the malfunction appear?
▶ Try to get a clear idea of the cause of the fault. Directly ask the (machine) operator.
▶ Document the work carried out.
▶ If you cannot rectify the fault, contact one of the contact addresses which
