Having some leveling issues on upper floor unit goes into leveling as soon as the star wheel flips heading in the up direction takes quite awhile to level. Sometimes at very end of leveling it jumps up in full speed for a second then stops at floor level.

Oh yeah its hydraulic maxton uc1a

The sequence sounds normal, but;

Is the lifts slowdown cam coming off of the limit wheel before hitting actual floor level?
Check the lifts cam to be sure it’s not falling away from the limit wheel allowing high speed to kick in for a second.
Have you verified the up high speed valve coil energizes near floor level?

Might be up leveling or up transition simply needs readjusting once the high speed issue is resolved.
