HOW TO…REPLACE THE INCLINE MOTOR OR MOTOR CONTROLLER
12. Prop up the deck. Use a large hex key in models with a hole in the rail for that
purpose. For other models, place something sturdy under the deck to prevent it from
collapsing during the remainder of this procedure.
13. Disconnect all wires to the incline motor (see the wiring diagrams on pages 6 and 7.)
14. Disconnect the ground and capacitor
wires from the motor controller board.
15. Remove the left and right lift nut
screws.
16. Remove the incline motor pin and clip.
17. Remove the incline motor.
18. Install the new incline motor in the
frame.
19. Insert the incline pin and clip.
20. Incline motors are shipped with the lift

that the distance from Adjustment Hole
“A” to Adjustment Hole “B” on the
incline motor is 9¼ inches (235mm).

roller.
