WARNING
Risk of injury if improper disassembly and disposal procedures
are followed!
Accumulated residual pressures, the heavy intrinsic weight of components
(rod, Safety Lock) and spring forces can cause serious injury.
Ü
Secure the danger zone.
Ü
Leave the Safety Lock assembled. Do not open the Safety Lock.
Ü
Secure the Safety Lock and rod separately, even if the Safety Lock is
fixed to the rod.
Ü
Do not reach through the openings in the housing and the rod.
13.1 Disassembly
Check the preconditions:
• The load (e.g. moving machine parts) secured by the Safety Lock is sup-
ported by other means or has already been disassembled.
• The Safety Lock and clamping rod are secured separately to prevent
them from dropping down.
Depending on the method of integration into the local plant, the Safety Lock
might be disassembled separately from the clamping rod or only together with
it. The following describes both cases.
Combined disassembly of clamping rod and Safety Lock
Follow this procedure:
1. Discharge accumulated residual pressures.
2. Disconnect the complete pressure supply from the Safety Lock.
3. Secure the Safety Lock and clamping rod separately.
4. Loosen the mounting screws of the Safety Lock and the rod.
5. Remove the Safety Lock from the machine together with the rod.
6. Connect a temporary pressure supply to pressure port L.
7. Apply pressure to pressure port L.
ð
The clamping system opens.
8. Pull the rod out of the Safety Lock.
9. Disconnect the temporary pressure supply from the Safety Lock.
