Safety instructions | Axial piston units 15/64
WARNING
Escaping hydraulic fluid mist!
Risk of explosion and fire hazard, 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.
Escaping hydraulic fluid due to leakage of machine/system components!
Risk of burning and risk of injury due to escaping hydraulic fluid jet!
In case of leakage at the axial piston unit, high-pressure fluid jets may escape.
▶ Depressurize the relevant machine/system component and repair the leak.
▶ Never attempt to block or seal the leak or hydraulic fluid jet with acloth.
Hydraulic fluid will explode when making contact with water.
Risk of explosion and fire!
▶ Do not bring hot hydraulic fluids in contact with water.
Electrical voltage!
Danger to life or risk of injury due to electric shock or property damage!
▶ Always diskonnect the voltage supply to the relevant machine/system part
before assembling the product and/or connecting or diskonnecting the
connector. Protect the machine/system against being re-energized.
Danger from unexpected 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 on apermanent basis (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 or not your machine requires additional safety measures for your
application to avoid unintentional actuation. If necessary, make sure these are
appropriately implemented.
▶ Wear suitable protective clothing.
