The end fitting on the body side of the gas spring is unscrewable and the thread is hollow.In this hollow, the user can insert a rod which will come to be posed on the valve (a nail will be able to make the deal). Then, it is enough to strike with small damped blows on this stem. Attention : Always the valve at the top and rod down.
When adjusting 2 gas springs at the same time, we suggest counting the strokes to remove the same amount of gas from both sides.Do not make more than 5 consecutive hits without first testing the GAS spring before (if necessary) repeating the procedure.
If you have emptied too much air, it is possible to refill the gas springs at the factory (Consult us via the contact form accessible on our site).
