Once the Jack is fully lowered, turn the Handle firmly clockwise to close the Release Valve. 2. Carefully position the Saddle of the Jack under the vehicle manufacturer's recommended lifting point. If equipped, the Elevating Screw can be used to alter the height of the Jack's Saddle; it is adjusted by turning it clockwise or counterclockwise. (See vehicle manufacturer's owner's manual for location of seam lifting point when lifting only one wheel and frame lifting points when lifting the entire front or rear end of the vehicle.)

If using two jack stands, position them at the same point on each side of the vehicle. 6. Center the vehicle's lifting point(s) on the saddle of the jack stand(s). Set up the jack stand(s) according to the manufacturer's instructions, making sure that they lock securely into position. Note: If using two jack stands they must be at the same height. 7. Place the Handle over the Release Valve and slowly turn the Handle counterclockwise to open the Release Valve and lower the vehicle onto the saddle(s) of the jack stand(s). Then, turn the Handle firmly clockwise to close the Release Valve. Bottle Jacks For technical questions, please call 1-888-866-5797. Page 5 Lowering Saddle Handle over Release Valve Fulcrum 1.
