OPERATING MANUAL FOR 791-5050A, 791-5160A, 791-5220A
ASSEMBLY 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.
OPERATING INSTRUCTIONS
This is the safety alert symbol used for the OPERATING INSTRUCTIONS section of this manual to alert you to potential
personal injury hazards. Obey all instructions to avoid possible injury or death.
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 THE VEHICLE TO POSITION OR REMOVE 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
THE VEHICLE TO POSITION OR REMOVE 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
This is the safety alert symbol used for the PREVENTATIVE MAINTENANCE section of this manual to alert you to
potential personal injury hazards. Obey all instructions to avoid possible injury or death.
1.
Always store the jacks stands in a well protected area where they 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 jack 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 NAPA 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. Premature
wearing or damage to components caused by loose or missing hardware is not eligible for warranty consideration.
WARRANTY
Please contact your local NAPA Auto Parts Store for details on warranty.
