the underside of the ramp and frame to support and keep the ramp in the raised pos-
ition.
7. Use a 9/16" socket to remove the two yoke ramp fasteners and remove the yoke from
the ramp. Note that the ramp will fall when the fasteners are removed. Make sure the
ramp is supported before removing the yoke ramp fasteners. Retain part(s) and/or
fastener(s) for installation.
8. 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 to raise
or lower as needed to adjust the calibration distance to 9" +/- 1/4" (23 cm +/- 0.6 cm.
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 to level 10 and then the yoke nut recalibrated.
