OPERATION
Lifting
1. Ensure that the vehicle is on a flat, hard and level surface and is free to roll forward and backward during the lift.

3. Loosen air vent screws (upper screws) on each hydraulic damper located on side of air cylinders.
4. Insert lifting beams fully to engage lock. For low pickup height, rotate the beams 180 degrees.
5. To adjust the location of the lifting beams, push the locking pin upward from underneath and pull out the lifting beams.
(see Figure 4)
6. Adjust bumper bolt to increase ground clearance. (see Figure 2 on page 4)
7. Make sure both saddles are positioned directly under the vehicle manufacturer's recommended lift points.
