We got a lift in from one of our customers that has a small tight shop and needs to move slowly with his lift. Lifting at a slow speed goes nice and smooth through the free lift but at the start of the second stage the lift starts to grab and jump as if the mast is in a bind. All rollers and bearings have been checked and lubed and there is not any sign of binding in the mast. When you lift at a normal speed all works fine. We have a Toyota in the shop that is basically the same truck and it has the same symptom ant the very same spot when lifting at a slow speed. We reconditioned the Schaeff in our shop late last year and the problem just showed up. Any ideas ???
Thanks
