Hyster H80XM:
Low power while driving.

I am working on a Hyster at a customers and the problem is this unit has very low power when you first start driving. Now I believe this is not and engine problem because while in neutral using the hydraulics there is plenty of power I can full out tilt and steer hard one way and the engine powers right through it. And as soon as I try to drive if feels like I'm starting out in second or third gear. Could this be the torque converter??? Or maybe filter problem.
Once this truck gets up some speed it really works well. But if you have a load on it and try going up a little ramp if feels like it is in second gear. ( this truck has only one gear and is Automatic)

Any help would be appreciated

the fortis of importjunkie's has a considerably different transmission than the XM seris of the original poster, I would suggest that importjunkie have the local hyster dealer do a transmission calibration as a first step. that will tell you if you have other problems.

Hi

Did you ever figure out what was going on with your forklift? My Hyster S40FTS is doing the same thing.

Thanks, Brian

i have a s50xl in the shop...and it does pretty much the same thing it has alot of power and when you drive it really lugs the engine down but not much driving power which to me has a torque converter problem...i suggest the first thing to check it the inching to make sure its not engaging at all and then still start checking transmission pressures first and trying a stall test if possible before jumping around..
