Escaping hydraulic fluid mist!
Risk of explosion and fire, health hazard, risk of environmental pollution!
▶ Depressurize the relevant machine/system component and repair the leak.
▶ Only perform welding work when the machine/system is depressurized.
▶ Keep open flames and ignition sources away from the axial piston unit.
▶ If axial piston units are located in the vicinity of ignition sources or powerful
thermal radiators, a shield must be erected to ensure any escaping hydraulic
fluid cannot be ignited, and to protect hose lines from premature aging.
Electrical voltage!
Risk of injury from electric shock or risk of property damage!
▶ Always disconnect the relevant part of the machine/system before installing the
product or when inserting/removing connectors. Protect the machine/system
against being re-energized.
Restriction of control function!
Risk of injury or property damage!
Moving parts in control equipment (e.g. valve spools) can, under certain
circumstances, get stuck in position as a result of 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 that remedial measures be taken
on your machine in order to bring the driven consumer into a safe position
(e.g. safe stop).
▶ If necessary, make sure these are properly implemented.
