Bosch A4VG A4VG 32 Series Instruction Manual page 13

Escaping oil mist.
Risk of explosion and fire, health hazard, risk of environmental pollution!
▶ Depressurize the relevant machine/system part 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 that any escaped 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 set up the relevant part of the machine/system so that it is free of electrical
voltage before you install the product or when connecting and disconnecting
connectors. Protect the machine/system against being re-energized.
Danger from unforeseen machine movement.
Danger to life or risk of injury. Unintentional or careless actuation of the manual
override of the solenoids can cause unexpected machine movements.
▶ Use the manual override only for functional testing or in the event of
technical malfunctions.
▶ Using the manual override permanently (e.g. by wedging, blocking) is
not permitted.
▶ The use of the manual override is only permitted with limited technical
data (e.g. 0.25 × maximum data).
▶ Check whether additional protective measures are necessary for the application
on your machine in order to avoid unintentional actuation. If necessary, make
sure that these are properly implemented.
▶ Wear suitable protective clothing.
Restriction of the control function.
Risk of injury or property damage.
Moving parts in control equipment (e.g. valve spools) can, under certain
circumstances, get blocked in position as a result of contamination (e.g. impure
hydraulic fluid, abrasion, or residual dirt from components). As a result, the flow
of hydraulic fluid 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 filter) 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 that these are properly implemented.
