Lift motor calibration
1. Lay the replacement lift motor on the floor in front of the treadmill. Connect the the lift
motor interface cable to the MC "LIFT" connector.
2. Connect the power cord and switch the power from OFF to ON. This will set the lift
motor to the calibration reference incline level "0".
3. Switch the power OFF and unplug the power cord.
4. Disconnect the MC "LIFT' connection.
5. Firmly hold the jackscrew and rotate the extension tube to adjust the calibration dis-
tance. The calibration distance is measured between the top of the extension tube nut
and the lift motor actuator housing. Adjust the calibration distance to specification
between 1 1/8 in - 1 3/16 in (2.8 cm - 3.0 cm).
IMPORTANT: Make sure the extension tube does not rotate after setting the cal-
ibration distance. Use tape to mark the extension tube position on the jackscrew.
