How do you remove your volume chamber plug

[corellon]

The title say everything.
I try to remove the volume chamber plug.
And it seam to be hard to remove.

Do you have a hint to remove that

Thank

Is it the first time it has been removed?
It should be as easy as getting a 4mm allen key and removing but if it's never been removed before it may require a little strength.
Keep at it theres no trick to it it's just tight.

Make sure your marker is degassed first.
