Procedure 5.3 - Calibrating the Lift Motor

1. In order to calibrate the lift motor, it is necessary to disconnect the lift motor from the ramp
assembly.
2. Set the on/off switch in the "off" position. Remove the front cover per Procedure 7.21.
3. Remove the two bolts that retain the lift yoke to the ramp assembly. Support the lift motor
and ramp assembly as you separate the lift yoke from the ramp assembly. Lower the ramp
assembly until it is resting on the rear lift cover.

number to 163 (5.31) or 223 (5.37).
6. Rotate the lift yoke on the lift motor drive screw until the distance from the upper surface of
the plastic nut in the lift yoke to the end of the drive screw is 6-9/16" (5.31) or 1-23/64"
(5.35). If the lift motor drive screw rotates the lift calibration number will no longer be 163
(5.31) or 223 (5.35). The lift calibration number must be 163 (5.31) or 223 (5.35) and the
distance measurement must be correct for the lift calibration to be correct. See Diagram 5.5.
