- Disconnect all cables led into thrust actuator from outside and remove from thrust
actuator.
- Place hood on carefully from above and fix in place with hexagon nut.
- Loosen grub screw inside torsion safety feature; screw coupling out of torsion safety
feature.

ATTENTION !
- The supply line for connecting up the thrust actuator must be in the dead state
i.e. disconnected while dismantlement work is being carried out. After being
disconnected, the mains power must be prevented from being switched back
on again accidentally.
- The system must be run down (depressurised state) as the valve cone is not
held without the thrust actuator and would thus be conducted by the system
pressure.
- Valve plug approximately in mid lift position - on no account supported inside a
seat!
