On the control panel, you will find a Vac & Seal/Stop button. Once you press it, the device will start the vacuum and seal process.
You can also push it during the process to instantly stop it.
One of the most important features is Vac Level which is used for selecting one of the two vacuum degrees (High or Low).

Another function for delicate items is Pulse, whose purpose is to let you control the vacuum pump by yourself.
In this way, you can apply the necessary amount of vacuum little by little.
Harvest Keeper tried to include as many useful features as possible, including a roll storage compartment and a built-in cutter.
These two are great for creating as many custom-sized packages as you desire.
However, you should note that their width cannot surpass 11 inches. On top of that, the machine cannot seal household bags.
To prevent a badly made seal, do not overfill the bags. It’s important to leave a two-inch free space above the food.
A function few other vacuum sealers are equipped with is Accessory.
