I saw your response to the following post in which you offered to email the poster the Smooth Fitness 9.45ST service manual.http://forum.treadmilldoctor.com/discussion/2649/smooth-fitness-9-45st-err-2-and-raised-rear-wheels - service manual
Would you also happen to have the service manual for the Smooth Fitness treadmill model 6.25?
I currently have the base apart exposing the treadmill and incline motors, etc. and planned to follow the directions here: https://www.treadmilldoctor.com/smooth-incline-calibration
to reset the incline as it won't return to the fully lowered position but my circuit board does not match the picture and there is no button or any other obvious way to reset the incline on the circuit board itself.
I'm guessing maybe it's a newer circuit board and the reset function is on the control panel instead?
Can you help? Do you know how to reset the incline to be able to travel to its lowest/level position?
