Assuming that you have already registered the marker for warranty via: https://warranty.planeteclipse.com/site/signin
The issue that you have has two potential contributing causes:
- Firstly the front number 020 NBR 70 o-ring on the Valve Body is not sealing correctly and consequently allowing air to pass inbetween the outside of the bolt guide and the internal bore of the body.
- The bolt bumper could be acting as a seal and whilst being forced forwards by this air, compresses the bolt spring, holding the bolt forward.
So, your first line of attack is to check your front 020 NBR 70 o-ring. Replace it and re-grease it. If necessary try a 20x2 NBR 70 in its place. If the marker still exhibits the same issues, then we will need to send you a replacement bolt bumper.
