14. Insert the jack handle into the
pump linkage.
15. Use an up-and-down motion
with the jack handle to raise the
wheel completely off the ground.
Hydraulic jacks are equipped
with a pressure release valve
that prevents lifting loads which
exceed the jack’s rated capacity.
16. Remove the lug nuts with the
lug wrench.
17. Replace the flat tire with the
spare tire, making sure the valve stem is facing outward on all front an
inboard rear wheels. If replacing the outboard wheel, the valve stem
must be facing inward. Reinstall the lug nuts until the wheel is snug
against the hub. Do not fully tighten the lug nuts until the wheel has
been lowered.
18. Lower the wheel by slowly turning the release valve
counterclockwise.
Opening the release valve slowly will provide a more controlled
rate of descent.
