Hitachi 2007 model. Dealer was no help. My machine has auxiliary lines on boom which makes me believe the valve is there but no control in cab. If the valve is there how do you control it? Electric over hydraulic? And does anyone know the gpm to auxiliary circuit? Thanks!
Good day You have unlimited options, you could buy the standard pedal hook the lines top and bottom of the main valve or with solenoid valves control via a button or switch. If you follow those lines back from the boom one line at least will connect to the main valve at the MCV, the other could connect to tank for a one way hammer set up. If you post a photo of the lines we can help out some more (see 152). Kind regards Uffex
is this a dash 3 machine? If so..... It was a dealer installed option. So, you would have to add the controls. It could be either electric over hydraulic or all hydraulic. While 2 of the kits shown below are no longer available, you could piece meal them. Or, contact someone like HCT https://www.hctkits.com/excavator-kits/ or HKX http://www.hkx.com/ to see what they offer.
