correctly. Verify that all mounting hardware and
critical components are also installed/adjusted
properly.
The following checklist is provided as a reference when

there is appropriate ground clearance in the retracted
position, and check for interference over the full
range of travel.

tilt/recline/lifter range for pulling, crushing or tight
bends.
