11 Disassembly and replacement
WARNING
Risk of injury!
Parts flying around due to the residual pressure that is still present after the
discharging may lead to serious injuries.
▶ Check the residual pressure in the diaphragm type accumulator using the
charging and test device.
11.1 Required tools
For the disassembly of the diaphragm type accumulator, you need:
• Charging and test device (for diaphragm type accumulator with
material number 0538103012 or for bladder and diaphragm type accumulators
with material number 0538103014)
• Open-end wrench
For further details on the wrench sizes, refer to chapter 7 "Assembly", table 5.
11.2 Preparing disassembly
▶ Decommission the overall system as described in the operating instructions of
the system.
Afterwards, prepare the disassembly of the diaphragm type accumulator as follows:
▶ Depressurize the hydraulic system.
▶ Make sure that the relevant system parts are depressurized and de-energized.
▶ Discharge the accumulator via the discharge device of the system. Please note
that the pre-filling pressure still exists on the gas side after hydraulic relief.
▶ Please decide whether a remaining gas pressure in the diaphragm type
accumulator is required or reasonable.
