Hoping you all might be able to help us out.

Our January 2002 build sl10 was working when we finished the last order. Started it up ( less than 2 months later ) to run another order and the jaws would not move. Monitor shows that it is clamping / unclamping.

Removed the chuck to inspect, the cylinder does not "seem" like it is jammed up??

Machine has sat a lot over the years ( we struggle to find turning work in our plant ). The fluid looks clean in the glass and the pressure is at ~ 350 psi.

Other notes:

While the monitor says it is clumping and un-clamping, it does not really seem that way?


Thanks for you time and any help you may be able to offer.

Stuck hydraulic valve? Are you actually getting power to the valve?

I agree.

Follow the Hydraulic hose if, possible to find right Valve...might be a button on the ends to manually move piston.

Thanks guys,

Going to go try to check on the valves now. Maybe they are gummed up??
