Braun Door 33657 Manuel D’Utilisation

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.

Channel Frame Applications:  

Secure mounting bolts as speci-

fied in Figure D.  

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).  

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.

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 

Instruction 28942.

Align mounting clamps 

with all-thread studs.

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.

The lift housing must be 

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.

Position the lift to achieve a 2” 

overlap between the deployed 

inboard barrier and the vehicle 

floor.
