komatsu pc75uu3 slow response to the hammer

dwagidig ยท 2013-04-17 21:10

The tramac 300 hammer that I have on the exc fires about a 1 1/2 second after you activate the pedal. There is a aux two way control box mounted after the main valve pack. The control box is switched to one way for hammering. There is also a relief on it but, it doesn't make a difference in hammer response. So far, I did not check for pressure and relief readings. This machine I recently acquired and I have no manuals. Everything is in japanese or something! I am stumped! Can someone help me please? Thanks
