Operating Instructions
Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the beginning of this
manual including all text under subheadings therein before set up or use of this product.
WARNING! TO PREVENT SERIOUS INJURY: 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: Check that the weight
is evenly distributed between the 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! TO PREVENT SERIOUS INJURY: 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.
7. Insert Mobility Pin into the opening located next
to the Stop Tab. Secure the Mobility Pin in place
by inserting the Safety Pin into the small hole
on the end of the Mobility Pin. See Figure B.
Figure B
8. 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! TO PREVENT SERIOUS INJURY:
Set both Jack Stands to the same height.
9. 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. Remove Safety Pin from the Mobility Pin.
Remove the Mobility Pin from the Base.
3. Raise the Handle on the Jack
Stands and lower the Posts.
4. Remove the Jack Stands. Use the floor jack
to safely lower the vehicle to the ground.
WARNING! TO PREVENT SERIOUS INJURY:
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.
