engine power is all right. Hydraulic pump was repaired a few days ago, pressures are fine. The computer doesn´s show any error !!! Problem is not constant - power is maximum or minimum and movements of machine are slowly. Many engineeres from Komatsu have tried to solve this out but can´t find the main problem.
Any advice please ??? Thank you
