JS3TA, JS6TA, JS12TA 3, 6, and 12 Ton Jack Stands (Pair)
ASSEMBLY INSTRUCTIONS
OPERATING INSTRUCTIONS
1. Install the support column in the stand where the support column teeth are facing toward the stand's locking pawl.
2. Raise the stand's locking handle to allow the column to go to its lowest position.
3. In order to prevent removal of the support column from the stand, use a hammer and flat end punch to hammer the jack's tab
in toward the column but not touching the column. Some stands are equipped with a bolt instead of a tab. In this case the bolt can
be threaded in toward the column until the bolt bottoms out. See figure 1.
1. Make sure the work floor is clean and free of debris and obstacles.
2. Chock the vehicle's tires that will not be lifted. Make sure the emergency brake is on and the vehicle's transmission is either in
the park mode or gear if a manual transmission.
3. Raise the vehicle to a safe working height and make sure the jack and vehicle setup are stable before positioning the jack
stands.
DO NOT CRAWL UNDER VEHICLE WHILE LIFTING VEHICLE OR PLACING OR REMOVING THE JACK STANDS
.
4. Position the jack stands right below the areas of the vehicle support points as specified by the vehicle manufacturer.
5. Lift the support columns as close to the vehicle as possible without the saddles on the columns coming in contact with the
vehicle. Make sure the support columns' teeth are engaged with the locking pawls.
6. Slowly and carefully lower the vehicle on the jack stands. Shock loads or loads dropped abruptly on stands can cause
premature metal fatigue or even stand failure depending on the weight of the vehicle and the speed of descent that impacts the
stands' support columns. The load should be supported in the center of the support column saddles, not the locating lugs of the
saddles.
DO NOT CRAWL UNDER VEHICLE WHILE LIFTING VEHICLE OR PLACING OR REMOVING THE JACK STANDS
.
7 Check the load for stability. If the load is not stable, lift the load off the stands and correctly reposition the stands.
8. When work is completed, raise the vehicle high enough off the stands where the stands can be easily removed.

PREVENTATIVE MAINTENANCE
1. Always store the stands in a well protected area where it will not be exposed to inclement weather, corrosive vapors, abrasive
dust, or any other harmful elements. The stands must be cleaned of water, snow, sand, grit, oil, grease or other foreign matter
before using.
2. Every stand owner is responsible for keeping the stand labels clean and readable. Use a mild soap solution to wash external
surfaces of the stand. Contact Matco Tools for a replacement label if your stand's label is not readable.
3. Inspect the stands before each use. Do not use the stands if any component is cracked, broken or bent. Do not use the stand if
it has loose or missing hardware or components, or is modified in any way. Take corrective action before using the stand again.
