Safe Use & Care
• Only use this appliance for its
intended use as described in this
manual.
• Always make sure the lid is
unlocked before plugging in and
disconnecting the appliance.
• Always unplug the vacuum
sealer when it is not in use, is
unattended, or when being
cleaned.
• For best results, use Cosori
vacuum bags, bag rolls,
containers, and accessories.
• This vacuum sealer is also
compatible with most 8” and 11”
vacuum sealer bags and vacuum
sealer bag rolls.
• When sealing multiple bags,
allow the vacuum sealer to
rest for at least 40 seconds in
between each bag to prevent
the device from overheating.
• DO NOT reuse bags after
storing raw meats, raw sh,
or greasy foods to prevent
contamination.
• DO NOT reuse bags that have
been microwaved or simmered.
Bags used for cooking should
not be used more than once to
help prevent contamination.
• DO NOT vacuum package
carbonated or sparkling
beverages as gas removal will
cause such liquids to go at.

comply with all the instructions
provided in this manual before
using the device. Failure to comply
with the instructions given in this
manual and/or using the device
