I mean when use accumolator we close one valve and open one vavle. When use handpump we open one valve and close one valve. Is that right? Why we have to do that? Can you explain working principle.

Can you explain why the valve is closed or opened in each mode. I dont understand the working principle.

@@marineengineerworks The first mode using electricity is we can slewing out or hoisting by electric motor. The second and the third mode only can slewing with valve, if want to hoist can only use the stick manually. Is this right??
