1. Turn the Handle counterclockwise to lower the Jack. Once the Jack is fully lowered, turn the Handle firmly clockwise to close it.

2. Carefully position the Saddle of the Jack under the vehicle manufacturer’s recommended lifting point. (See vehicle manufacturer’s owner’s manual for location of frame lifting point.)

3. Pump the Handle until the top of the Jack’s Saddle has nearly reached the vehicle lifting point. Position the Saddle directly under the vehicle’s lifting point.

4. To lift the vehicle, pump the Handle of the Jack. Use smooth, full strokes.

5. Once the vehicle is raised, slide a jack stand of appropriate capacity (not included) under a proper lifting point referred to in the vehicle owner’s manual. Always use two jack stands, position them at the same point on each side of the vehicle.
   WarninG! The rated capacity of jack stands is per pair, not the individual capacities combined unless specifically noted on the product by the jack stand manufacturer. Do not exceed rated jack stand capacity. Ensure that the vehicle support points are fully seated in the saddle of both jack stands. Use a matched pair of jack stands per vehicle to support one end only. Failure to do so may result in the load suddenly falling, which may cause personal serious injury and/or property damage.

6. Center the vehicle’s lifting point(s) on the saddle of the jack stand(s). Set the jack stand(s) to the same height according to the manufacturer’s instructions, making sure that they lock securely into position.
