My Pro Form 580 XP slows down suddenly while on, and speeds up again almost making me fall off of it. Anyone know why this could happen? The manual is no help
If you have not ever lubricated the running deck then I suggest doing so . What happens is that the lack of lubrication will tend to make the belt drag thus slowing down the belt making the motor control board to try to compensate the drag.
