This is easily solved.😊
When the o-ring holder has loosend from the bayonet and is stuck inside the lance, it would look something like this:
The o-ring holder is rather easy to pull out, but if it is quite stuck, one can loosen it by using:
pair of pliers
The last one is quite handy, as one gets something to pull with at the same time.
Here is how the bayonet looks without the o-ring holder, check to see if the o-ring is still inside the bayonet or needs replacing:
Use the AVA First Aid Kit, to replace both o-ring and holder. If you need the bayonet/ nozzle before you are able to get a hold on the AVA First Aid Kit, you can move an o-ring and holder from another attachment to the one with a missing holder.
We hope this explanation was helpful.
