Discussion:
Mast stops before coming all the way down

I'm new to your forum, thanks so much for all the great info.
Just bought a Yale GLC050, it was working perfectly,until I raised the mast all the way to it highest point. The top rollers came out of the tracks, like the ram over extended. It would come down to within 6' of the ground and stop. I took the line loose at the bottom of the center cylinder to see if it would let me push it back down with my frontend loader bucket. I was able to get it all the way down. Hooked up the line and tried going up just a couple of feet and then back down. It stop again about 4 ft from off the ground. Any ideas guys?

You will need a seal kit and check valve for the free lift cylinder. I am assuming this is a three stage mast. There is a check valve in the base of the free lift cylinder ram. It sounds like it has came apart or is plugged. This will cause it to not lower properly.
