Restriction of control function!
Risk of injury or property damage!
Under certain circumstances, moving parts in control equipment (e.g., valve spools)
can get stuck in an undefined position due to contamination (e.g., impure hydraulic
fluid, abrasion or residual dirt from components). As a result, the hydraulic fluid flow
and the build-up of torque in the axial piston unit can no longer respond correctly
to the operator's specifications. Even the use of various filter elements (external or
internal flow filtration) will not rule out a fault but merely reduce the risk.
▶ Check whether your application requires remedial measures on your machine in
order to bring the driven consumer to a safe position (e.g. safe stop).
▶ If necessary, make sure these are appropriately implemented.
Limitation of load-holding function in lifting winches!
Risk of injury or property damage!
Moving parts in high-pressure relief valves may in certain circumstances become
stuck in an undefined position due to contamination (e.g. impure hydraulic fluid).
This can result in restriction or loss of load-holding functions in lifting winches.
▶ Check whether the application on your machine requires additional safety
measures in order to keep the load in a safe position.
▶ If necessary, make sure these are appropriately implemented.
