Having a problem on an old bobcat 610 the lift arms won't lift when I attach the bucket . It starts to to lift then looses pressure . The bucket tilt is working fine . Also the lift arms will lift without the bucket . Any input would be Appreciated thanks Adam

You answered your own question. You dont have enough pressure. You might have a weak hydraulick pump or leaking internally inside the valve. I wouldnt think it would be the coupler because u said the tilt works fine.

Can you lift the front end of the machine with just the tilt? If you can it sounds like cylinder seals in the lift cylinders need replacing. disconnect the line on the bottom of both lift cyls, plug one and put a gauge on the other and see how much pressure you have at that point when you try to lift it.

Do you have aux hydraulics? if they are stuck on, they may cause this issue....
