If a thrust reverser cowl is pumped upwards open, then it is not permitted to move it to deploy (aft) too, manual or with hydraulic power. Also the other way around, a reverser which is deployed aft, may not be pumped open (up). This is because the translating sleeve will come in contact with the fairing mounted on the pylon, as it will be damaged resulting in a removal of the sleeve for repair. A limited extension of the sleeve is possible, however, but only at the outboard reverser half with dismantled fairing. Therefore always pay attention on the position of the sleeve when working with it!
DEPLOYED…
OR up, but never both at the same time !
