What is the reason why the hydraulic impact turning device of Hangzhou steam turbine cannot be hooked up when it is turned on automatically?

As shown in the picture, it only moves for the first time when turning on automatic, and it cannot be turned on again. Please give some advice.
The following content is for reference only and shall be subject to the manufacturer's instructions.：
I once encountered a Hangzhou Automobile back-pressure steam turbine. The cranking hook was decoupled and the cranking pump piston could not move downward, causing the cranking to not move.
This is also caused by the fact that the piston rod cannot reach the bottom during the downward movement and is blocked by the shrapnel and cannot hang on the ratchet!
I tried several times, but the cutting method was problematic again. Ask the manufacturer. It shouldn't be cut in any position.
