Operation
Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the
beginning of this document including all text under subheadings therein
before set up or use of this product.
WARNING! Use as matched pair to support one end of a vehicle only.
Supporting a Vehicle
1. Make sure the vehicle does not exceed
the capacity of the Jack Stands.
Note: That is evenly distributed
weight per pair of Jack Stands.
You must evenly distribute the
weight or the Jack Stands may fail,
causing severe injury or death.
Only apply the load vertically.
WARNING! If a vehicle drops on the
Jack Stands (even if it is under the
weight capacity limit), the principle
of “dynamic loading” takes affect.
The force of the weight falling may cause
the Jack Stands to fail. A vehicle weighing
much less than the Jack capacity may cause
the Jack Stands to fail if dropped on them.
Note: Do not move the Handle when the
Jack Stands are supporting a vehicle. The
shear pin is designed to shear in the event
the user attempts to move the Handle while
supporting weight. If the pin shears, do not
use the Jack Stands again until the shear
pin is replaced by a qualified technician.
2. Examine Jack Stands for cracks or
damage before each use. Do not use
if even a minor crack, bend, or other
damage/deformation appears. Discard
Jack Stand if damaged or deformed.
3. Raise the Handle on each Jack Stand
to completely lower the Post.
4. If your are raising only one end
of the vehicle, block the tires
that remain on the ground.
5. Following the instructions in your
floor jack manual, raise your
vehicle to just above the minimum
height of your Jack Stands.
6. Slide your Jack Stands to the proper
position points referred to in the
vehicle owner’s manual. Make sure
the Jack Stands are on the same point
on each side of the vehicle. Move the
Handle up, and raise the Jack Stands
until they are just below the jack contact
point on the vehicle. Center the load
on the Saddle of the Post. Release
the Handle so that ratchet catches on
the Pawl. Gently lower the vehicle with
the floor jack. It may drop down a very
small amount until the ratchet catches
on the Pawl. Repeat on other side.
WARNING! Set both the
Jack Stands to the same height.
7. Determine if the vehicle is stable.
If not, raise the vehicle and
reposition the Jack Stands.

Removing the Jack Stands
1. Raise the vehicle with a floor jack to
take the load off of the Jack Stands.
2. Raise the Handle on the Jack Stands
and lower the Posts.
3. Remove the Jack Stands.
Use the floor jack to safely lower
the vehicle to the ground.
WARNING! Do not use Jack Stands
as a permanent stand for the vehicle.
Use them only while making repairs, then
immediately lower vehicle to the ground.
