11 Disassembly and removal
WARNING
Danger of damage to property and personal injuries at energized or pressurized
system parts!
For works at pressurized or energized system parts, there is a danger of injury
by escaping hydraulic fluid or electric energy.
▶
Before disassembly, ensure that the hydraulic system is depressurized, and the
electrical control is de-energized.
CAUTION
Falling of an incompletely disassembled valve!
An incompletely disassembled valve may fall down and cause injuries.
▶
During disassembly, secure the valve against falling.
Have sufficiently dimensioned collecting containers, sufficient cleaning cloths and
medium-binding materials ready in order to collect or bind leaking hydraulic fluid.
1.
De-energize and depressurize the relevant system part.
2.
Disconnect the electrical connections professionally.
3.
Prepare a container for collecting leaking hydraulic fluid.
4.
Use suitable tools to loosen the valve mounting screws of the valve.
5.
Remove the valve mounting screws and remove the valve from the
connection
surface.
6.
Collect escaping hydraulic fluid in the provided container and dispose of it
properly.
7.
If the valve is to be returned to the manufacturer for repair, please close the
valve connection surface using the supplied protective plate or protect it using
equivalent packaging in order to avoid contamination and damage.
8.
Close the hydraulic channels of the subplate (on the customer side) to avoid
contamination.
If the valve is exchanged, all further steps are analogous to mounting, see chapter 7
“Assembly”.
