6 Measure a distance of ¼ inch along the gas spring shaft from the bottom of the gas spring outer housing
and mark the shaft location with painters tape. This is the level 1 calibration reference mark.
CAUTION: DO NOT scratch, write on the gas spring shaft, or use tape that leaves a sticky residue to mark
the reference distance, these items can damage the housing inner shaft seal.

Manually raise the lift platform (compresses the gas spring) to the 1/4 inch reference mark “painters
tape” and secure the lift platform position. You can use a block, shims, or a ratcheting strap
(recommended) to hold the lift platform in position while reattaching the lift motor to the platform.
8 Rotate and adjust the lift actuator tube so that the lift actuator tube and lift platform bracket mounting
holes align. Insert the clevis pin and secure with the hitch pin.
9 Grasp and attempt to move the lift motor to make sure the upper frame weldment mount is a snug fit
(very little connection play). If loose, make sure that the correct mounting bolt or bolt/bushing is installed,
repair as necessary.
10 Remove the painters tape from the gas spring shaft.
11 Clear the lift motor platform area from any obstructions (shims, blocks, etc.) that can interfere with the
lift system up/down movement.
12 Reinstall the left/right flat belts and the flat belt keeper bracket.
13 Access the CROSSRAMP hardware validation program.
14 Set the Cross Ramp to level 5.
15 Verify the A/D value is between 212 and 216.
16 Verify that the gas spring outer housing to lift platform clearance is between ¼ to ¾ inches.
