3. 2.3. Turn adjusting nut -2-  to the right = vehicle higher - turn to the left = vehicle lower.
4. 2.4. Lower the vehicle onto its wheels (remove pit lifter).
5. 2.5. Compress (pull down) vehicle once and allow it to spring back freely. Then check the vehicle height and wheel loads.
6. 2.6. After you have adjusted the lock nut(s) -1-  on the front and rear axle, tighten with special tool hook wrench 9647  together with a torque wrench. Tightening torque = 50 Nm (37 ftlb).
