Yes there is an adjustment. My problem has been that over time the slide does not go fully in and sticks out an extra inch or two. Maybe your issue is similar. What I do is extend the generator slide and crawl underneath. You will see a motor with two adjustment screws. I mess with one or the other until the step reacts the way I think it should. I would only go about a turn at a time and keep track of what you have done, so you can better understand which adjustment screw does what. I do not have a manual that goes with that motor, so that is why it is kind vague as to how the adjustment goes. Good luck.
