Table 9 and Table 10 may help you when troubleshooting. The tables make no
claim for completeness.
Specific notes on troubleshooting on your axial piston unit can be found in the
product-specific instruction manual.
Issues may occur in practice that are not listed here.
Only authorized personnel may perform troubleshooting inside asafety area
designated by the machine manufacturer.
14.1 How to proceed for troubleshooting
▶ Perform troubleshooting if possible with reduced operating data
(e.g.slowlyswinging in or out and slow pressure increase).
▶ Use asystematic and targeted approach, even when pressed for time. Random,
indiscriminate disassembling and changing of settings could make it impossible
to determine the original cause of the fault.
▶ First get ageneral idea of how your product works in conjunction with the entire
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:
–Have there been any changes to the application conditions or operating range
of the product?
–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: What changes?
–Has the hydraulic fluid been changed?
–Has the product or machine been used as intended?
–How does the malfunction appear?
▶ Try to get aclear idea of the cause of the fault. Directly ask the (machine)
operator.
▶ Document the work carried out.
▶ If the fault cannot be corrected, please refer to one of the contract addresses at:
