I added a thumb I bought from showtime Fabricators. Thumb went on easily. The problem is the Auxiliary valves have not really been used since machine is new. I have pressure (2700 psi) to open the thumb but no flow or pressure to close. I don't know where to start. Foot controller or main auxiliary valve ? I have a repair manual, wish I had a parts manual for better Identification of the valve and hose locations.
Good day & welcome Your post describes the Auxillary is set up for hammer, take some picts. of the lines. Kind regards Uffex
Good day The attached file may help out. Kind regards Uffex
Thanks for the reply. I found my answer. To get the thumb to go two ways all I had to do was switch a valve on the right side of cab through a hole with a rubber plug. I believe the other position is for auxiliary using a hammer.
