On the right hand side of your Positiv U600 there are 3 levers. The lever closest to your backrest adjusts the back angle. Lift the lever and adjust to a comfortable position. Once happy, release the lever to lock in place.
Sometimes, over time, the gas stem can become a little stiff when trying to adjust the height. A quick and easy fix for this is using WD-40 or Vaseline. Apply a light layer of grease to the gas stem, then try adjusting the gas stem 3-4 times. The gas stem should now adjust easily.
On the left hand side of your Positiv U600, you will find the seat slide lever. Lift the lever until you are happy with your position, then release the lever to lock in place.
On the back of your Positiv U600 backrest there is a lumbar pump. Use the pump to inflate the lumbar support to optimal comfort.
If you need to deflate your lumbar, simply push the valve button on the pump.
Your backrest is on a ratchet height adjustment system. Simply lift the backrest to adjust the height of it.
