Strange electric pallet jack problem - Video links to see for yourself

Been this way since new (2012 model with 2.5 hours at present) Twist forward motion grips, jack moves, twist more, jack continues to move at aprox the same speed, keep twisting and suddenly it picks up speed..a lot...like double the speed.....no smooth transition.

Reverse is better, but even there the speeds change in small steps rather than a seamless transition.

Dealer has made computer adjustments on two different occassions. The pot transitions look ok on the computer. They are tapped out on fix possibilities. Latest talk is that is "just the way it is" for that model.
(Curtis controller, if that means anything)

Do you guys agree the pallet jack is defective ?

Well, that doesn't sound right to me. Don't know this truck. But I know the Curtis AC control can be adjusted on (too) many wparameters. I've been struggling with that in a different truck with a Curtis AC control.

The Curtis control can absolutely be adjusted better, but you'll probably need a mechanic who has experience with this. When you know the type of curtis control you can find the manual of it on the internet.
