CAUTION!
Before raising the wheel off the ground, make sure
that the jack will not damage surrounding truck parts
and adjust the jack position as required.
NOTE: If the bottle jack will not lower by turning the dial
(thumbwheel) by hand, it may be necessary to use the
jack drive tube in order to lower the jack.

Raising the vehicle higher than necessary can make
the vehicle unstable. It could slip off the jack and
hurt someone near it. Raise the vehicle only enough
to remove the tire.
