5. If the calibration distance is not to specification (lift motor calibration distance: 9" +/- 1/4"
(23 cm +/- 0.6 cm), continue procedure to adjust the Lift Motor Cal Distance.

6. Remove the Ramp, see
"Ramp Assembly Replacement" on page 187
. Do not change
the incline level during the ramp removal, maintain the incline level at 10.
Note
: The ramp and ramp front cover must be removed to disconnect the ramp from
the lift motor yoke.
7. Tilt the jackscrew forward out of the front tower weldment. Then use one hand hold the
jackscrew fixed and the other hand to rotate the yoke nut around the jackscrew in one
full turn increments to raise or lower as needed to adjust the Lift Motor Cal Distance to
9" +/- 1/4" (23 cm +/- 0.6 cm. Make sure that the yoke is pointing to the back of the
machine (opposite the lift motor) when measuring the Lift Motor Cal Distance.
IMPORTANT
: It is important to keep the jackscrew fixed (not allowed to rotate) as the
yoke nut is being adjusted. If the jackscrew does rotate during the adjustment, the lift
motor will need to be reset at level 10 and then the Lift Motor Cal Distance re cal-
ibrated.
