Good morning, it is my first message and the first thing to thank everyone. I would need the Komatsu PC-340-LC workshop manual. In case there is no possibility of finding it, I tell you the problem, in case there is someone who has happened to him in this machine. The elevation is slow, the other movements are correct, depending on my tests, the pump is fine and the sensor and the flow rate of flow too. Before dismantling distributor, I would like to have information. Cordial greetings and thank you very much.
