Hi guys,
For the last three weeks our PC210-8 Komatsu is acting slow. The boom tracks and stick is completely slow while the bucket speed is reasonable. Had the local Komatsu electricians and hydraulic mechs work on it together for 12 days but no use. They said they have to open the main control valve and pump and I 100% think there is no problem with it. The electrician says that they have done their part according to him and there is no electric fault. The rock breaker works fine. Raising the boom and stick is very slow but comes back normal. The tracks are slow in both directions. Before the machine used to act slow around 3 to 4 hours of work. Now its slow even when the machine is cold. Any clues guys.
Thanks
Rockfall
