|You just need to put on the top part (not the screw on part) on your mason jar.|
|Put on the jar sealer|
|grab the little hose thingy on your sealer and stick the nozzle in the sealer|
|press the button on the machine|
|and the rest is a piece of cake!|
When the sealing is done, you just remove the jar sealer and screw on the screw on part (although you don't really need to). Good luck popping it off! You actually need to get a butter knife to pop it off! Vacuum means TIGHT! and fresh.
