year 2000, 753 hydraulic controls

[antoeknee]

Hi all, I have Bobcat 753 year 2000, G model I think? triangle lights. I have had it two years now and have only used it with its bucket and with some forks. In the back of my barn was an old old backhoe which I used to use on a 1970's M371. Today with not too much work I managed to couple up the old backhoe to the 753. Once I got the hydraulics hoses attached I jumped in and started her up. I have no manual so had no idea as to what switches would do what, after a few seconds I got lucky and the backhoe began to work as it should. I turned it off for a few minuets whilst I went and got someone to show off to, but when I returned and started it up again I could not get the hydraulics working properly. The only way the backhoe controls would work as they should was if I pushed and held over, the right hand sticks thumb switch to the left. If I turn on the aux hydraulics with the right hand sticks trigger and then try to operate the backhoe the hoses would twitch and struggle but nothing would work. Do the other switches on the controls do anything? Any help much appreciated. It did definitely work as it should before I turned it off. Thanks

Pressing the trigger after you hit the button on the dash should keep the oil flowing to operate the backhoe
