The purchased gas springs (350N or 700N) cannot be pressed, is there a lock or are they broken?

All our gas springs are pre-tested so it is unlikely that they are broken. There is no lock or anything like that so they can be pressed immediately. However, the 350N and especially the 700N gas springs are very strong and many people sometimes underestimate that. Because of the novelty, it may be a bit stiff at first and you often have to push twice as hard on the first press as would be expected. So on 1 gas spring of 700N, 140 kg (1400N) may be needed for a short time to press it, then just the 700N (70 kg) that is expected.
