Caution
Use of an air wrench or other power
tools with the hoist mechanism is not
recommended and could damage the
system. Use only the tools supplied with
the hoist mechanism.
5. Insert the hoist end (10) through the
hole (9) in the rear bumper and onto the
hoist shaft.
Do not use the chiseled end of the wheel
wrench.
6. Raise the tire part way upward. Make
sure the retainer is seated in the wheel
opening.
7. If equipped with a spare tire cable, orient
the cable by rotating the spare tire so
that the cable is by the frame
attachment location.
8. Raise the tire fully against the underside
of the vehicle by turning the wheel
wrench clockwise until you hear two
clicks or feel it skip twice. You cannot
overtighten the cable.
Vehicle Care
