12 Disassembly and replacement
Pressurized press components due to stored pressure energy (e.g. press
slide working under gravity, pressurized lines over 50 bar according
to EN 289, par. 4.3.1.2) even after switching off the energy supply!
Ejection of valves and leakage of pressurized hydraulic fluid!
Danger to life! Risk of injury! Explosion hazard, risk of fire, health hazard,
environmental pollution! Damage to property!
▶ Before working on the press module, check that the EMERGENCY stop on
the press is effective and that the power circuit is disconnected from the
press module. Gravity-loaded axes must be in the lowest position, if possible,
or the load must be held securely by a mechanical restraint device.
▶ Secure the press against restarting by selecting the OFF operating mode and
then removing the key.
▶ Never try to stop or seal the leakage or the hydraulic fluid jet using a cloth.
▶ Do not disconnect line connections, connections or components as long as the
press module is pressurized.
▶ Check the pressure at the provided measuring ports only after the hydraulic
fluid jet has subsided.
12.1 Required tools
Observe the specifications of the machine manufacturer. You moreover need:
• Suitable tools for opening the screw connections
• Suitable lifting devices
• Oil pan
12.2 Preparing for disassembly
Prepare disassembly of the press module as follows:
▶ Decommission the overall machine/system as described in chapter 11.
▶ Keep the disassembly tools and suitable lifting devices ready.
▶ Have sufficiently dimensioned containers, residue-free industrial wipes and oil
binding agent ready in order to collect or bind leaking hydraulic fluid.
