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.
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. Remove the Pin on each Jack Stand
to completely lower the Post.
Removing the Jack Stands
1. Raise the vehicle with a floor jack to take
the load off of the Jack Stands.
2. Remove the Pin on each Jack Stand
to completely lower the Post.
3. Remove the Jack Stands. Use the floor jack
to safely lower the vehicle to the ground.
4. If you 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. Remove the Pin, and raise the Jack
Stands until they are just below the jack contact point
on the vehicle. Align the holes in the Sleeve with
the hole in the Post and insert the Pin all the way
through. Gently lower the vehicle with the floor jack.
WARNING! TO PREVENT SERIOUS INJURY:
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.
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.
Maintenance and Servicing
Procedures not specifically explained in this manual must
be performed only by a qualified technician.
TO PREVENT SERIOUS INJURY FROM TOOL FAILURE: Do not use damaged equipment.
If abnormal noise or vibration occurs, have the problem corrected before further use.
1. Periodically clean the bottom of the Bases and
top of Posts of any dirt, grease, or debris.
