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 in 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 saddle columns as close to the vehicle as possible without the saddles on the columns coming in contact with the vehicle.
Insert the locking pin.
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 decent 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.
