Do not overstuff the bag; leave enough empty length in the open end of the bag (at least 2.5 inches) so that the bag can be properly placed in the vacuum chamber.
Do not wet the open end of the bag. Wet bags may not seal properly.
Work with vacuum sealer bags that have texture on one or both sides.
Close and lock the lid till you hear two "snap" sounds.
Dry or freeze the moist food before starting the vacuuming process.
Preheat by sealing several times to ensure better sealing effect.
Read the user manual or watch video carefully before using the machine.
