Pressurized and energized system parts!
When working on pressurized and energized system parts, there is the danger of
injury by leaking hydraulic fluid or electric shock.
▶
Ensure that the hydraulic system is depressurized and the electrical control de-
energized before the disassembly.
Incompletely mounted valve components falling down!
Incompletely disassembled valve components may fall down and cause injuries.
▶
During the disassembly, secure the safety valves against falling down.
Have sufficiently dimensioned collecting containers, non-linting cloth and medium-
binding materials ready in order to collect or bind leaking hydraulic fluid.
1.
Switch off your system, de-energize and depressurize the system and secure the
system against restarting before all disassembly works.
2.
Unload the hydraulic accumulators, if applicable.
3.
Provide for a clean environment during the disassembly.
4.
Prepare a container or a pan for collecting the leaking hydraulic fluid.
5.
Detach the safety valve from the pipelines, flange connections or the valve
installation surface using appropriate tools; collect any hydraulic fluid that might
leak in the provided tank. Dispose of the hydraulic fluid properly.
WARNING! Heavy components! When lifting safety valves or components with high
weight, there is the danger of damage to property and personal injuries.
▶
Please observe the safety instructions in chapter 6 "Transport and storage".
6.
If the device is to be returned to the manufacturer for repair, please close the
ports using the transport protection or protect it using equivalent packaging in
order to avoid contamination and damage.
