CAUTION
When making changes to adjustment nuts on
cable end or latch bar stud always leave at least two threads
showing between nut and end.
Note: Latches may not click in at the same time when vehicle is
being raised. They should be close. Be sure all four corners have
passed the locking latch bar slot before lowering lift on locking
latches.
IMPORTANT
Cotter pins are usually good for onetime use
only. Replace any cotter pin, if removed, with a new cotter pin.
