Abnormal

Press black seal foam/layering, black
tape, clean the upper and lower sealing
areas with a dry cloth, lock the buttons on
both sides and seal.
The left and right latches are not
locked tightly, the bag sealing area is
uneven (black sealing cotton/loose
layering, the black tape is wrinkled),
the machine does not start heating.
Use the packaging bag suitable for vacuum
machine to keep the opening of the bag
smooth and without damage; open the
cover to flatten the sealing cotton,turn over
to the other side, or replace the substitute
bags. relocate the opening of the bag to the
required position, keep the opening of the
bag smooth, reserve enough sealing width
on one side of the opening (generally
about 8cm), and then put down the cover to
lock the left and right buttons.
Air leakage (bag broken, sealing foam
off/uneven(comes with indentation),
bag opening not cut and smooth, bag
opening not placed inside the exhaust
cavity, bag opening wrinkled/over-
lapped, bag being filled too full or bag
pre-seal width insufficient, and the
non-vacuum machine is used for
packing bags).
Air pump works,
but does not
pump the air
Vacuum without
sealing
Air leakage and incomplete
evacuation.
Uneven heat-generating compo-
nents, bag opening creases/over-
laps.
The bag is not suitable for a vacuum
packaging machine, the adhesive
tape attached on the surface of the
heating component falls off/is
damaged, and the sealer is not
suitable for wet pumping.
The size of the selected bag is too
large, air leakage.
In order to use the product better,
the machine is equipped with
automatic protection mechanism
(temperature sensing).
Select the bag whose size meets the
requirements of the product, and press "no
pumping" to confirm the fault removal.
Clean/keep the surface of the sealing
area clean and smooth, and keep the bag
opening flat.
Choose suitable packaging bags for
vacuum packers, choose dry/wet mode
according to the type of seal, keep the
seal area clean/adhesive tape intact
(damage need to be replaced).
Choose the bag whose size meets the
requirements of the product.
When the product protection is reached/
approached by several consecutive uses,
uncover the top lid, place the product in the
cooler for 5~15 minutes before use
(detailed evacuation/sealing operation
requirements can be found in the product
manual).
