Adjusting the O-ring
Having problems with airtightness? Here is a short guide of how to adjust the o-ring.
1. Locate the O-ring
1. Use a knife or similiar tool to flip out the o-ring from the groove on the inside of the lid.
2. Remove and adjust
2. Take out the O-ring on the inside of the lid, turn it around and then put it back in place and close the lid firmly three times to ensure it's positioned correctly. Check if the airtightness has improved.
If not, lubricate the O-ring with neutral vaseline or similiar grease, put it back, and then try again after repeating the procedure of opening and closing the lid.
3. Thats it! Well done!
