Hello All,
We have a probably with our Furukawa HCR 1200 DSIII drill machine.
At begin of the day when we start to work,machine work at it best,but after a while like 20 minutes, it's start to slow down the drilling speed.
Has checked drifter and all other internal parts of the hammer, resealed whole hammer but problem is still the same.
No sing of over hitting the engine hydraulic oil.
Any suggestion on this, what it could be?
