Attach Mounting Brackets to Vehicle Frame

Mounting bolts must be routed horizontally through the verti- cal face of the “L” brackets and framing members as shown in Figures D, E and F.

Eight 3/8-16 x 1-1/2" hex bolts are supplied for bolting the all- thread mounting brackets to the frame (two per bracket). Oval slotted mounting holes are pro- vided in the mounting brackets to allow adjustment. Carefully drill 25/64" (.390") diameter mounting holes at the center of the oval mounting slots.

Box Frame Spacers: Position tubing spacers as shown at right to prevent collapsing the box frame. Carefully drill a 25/64" (.390") diameter mount- ing hole through one side of the box frame. Drill a 5/8" (.625") diameter hole through the opposite side of box frame to allow installation of spacer. Cut spacer tubing to length (equal to thickness of box frame).

Thread two 3/4" hex jam nuts fully onto each mounting bracket all-thread stud. Place one large diameter flat washer onto each all-thread stud (use tape to hold in place). See Figures G and H.

Carefully position lift under vehicle (aligned with mounting brackets). Position (slide) the four lift mounting clamps along the sides of the lift hous- ing until aligned with mounting bracket all-thread studs. See Figure G.

Note: The two outboard mounting brackets should be positioned a maximum of 16” from the end of the cassette. See Figure J.

Carefully raise lift into position as high as possible (height adjustment outlined below). Place one large diameter flat washer onto each mounting bracket all- thread stud. Thread two 3/4" hex jam nuts fully onto each all-thread stud (up against lift mounting clamp).

Shift lift and mounting brackets left-to-right as needed (lift must be centered in door opening).

Tighten the 3/8" bolts securing mounting brackets to the frame. Torque Specifications: 25 to 30 foot pounds.

Dimensions A, B, C and D must be equal

B (within 1/16").

Note: A longer 3/8-16 bolt will be required for box frame appli- cations. Secure mounting bolts as specified in Figures E and F.

All fasteners must meet FM- VSS 571.403 Section 6.3.

Shipping Block Removal: Wood blocks are placed in the lift housing to prevent lift dam- age during shipment. Remove shipping blocks from platform and carriage before running (activating) lift. Refer to

Height Adjustment

The lift housing must be aligned with vehicle chas- sis. Adjust the 3/4" hex jam nuts on the all-thread mount- ing studs at all 4 corners of the lift until dimensions A, B, C and D are equal (within 1/16"). See Figure J.

In-Out Positioning

Position the lift to achieve a 2” overlap between the deployed inboard barrier and the vehicle floor.

Tighten upper set of 3/4" hex jam nuts (with flat washer) down to the lift mounting clamps. Tighten jam nuts. Torque Specifications: 100 to 120 foot pounds.
