For the SINBO (DZ-280/A) light commercial vacuum sealer, we have found these directions quite helpful in order to get a great vacuum and seal.
1) Turn the power switch
off & open the top cover by lifting the lid gently. You may have to unlock
the right side and left side lock. Push
down on one or both left &/or right corner spots marked lock to release the
2) Practice a few seals
on your bag before starting the vacuum process to determine the time setting
needed. Adjust the seal time setting for
the bag being sealed. You can start at 3
or 4. After sealing a few packages you
may need to drop down a number or two because it will take less time to seal
additional bags once you have been sealing consecutive bags.
3) Now you can start the
vacuum process - Extend the snorkel/nozzle by pulling the snorkel slide forward
until it locks into place. You will
locate the snorkel in the upper center section of the sealer.
4) Place the filled bag
with one layer below the snorkel and one layer above the snorkel. The bag will sandwich the snorkel. The snorkel will be inside the bag.
5) Close and lock the
cover by pushing down on both the right side and left side lock. You will know
it is locked when you hear it click in place.
6) Turn on the power
7) Tips for getting the
best vacuum: Make sure the product that is in the bag is placed evenly
throughout the bag- best placement is in the center of the bag. This will keep the snorkel from being blocked
by the loose bag. While vacuuming the
bag you may need to rub the layers of the bag between your fingers if the loose
bag blocks the snorkel. The sound will
change when the snorkel is blocked. With
a little practice you will soon be getting the best tightly vacuumed package.
8) After the package
reaches the correct tightness, momentarily push down with both hands on the seal
bar and release and quickly push down again and hold the seal bar with even
pressure until the seal light flashes and you hear the beep that indicates the
seal is complete. The reason that the
seal bar is pushed down and released and quickly pushed down and held is to
prevent the snorkel from being trapped in the sealing area. This is the best
method for allowing the snorkel to retract fully.
9) Push down on both the
right side lock & left side lock until the cover releases and lift the lid
and you can now remove the sealed bag.
10) To seal the next
bag, turn off the power switch and start at step 3) to begin the process of
vacuuming the next bag.
Note: When the SINBO
vacuum sealer gets too hot you will hear a warning sound & the seal will
become irregular. The machine should be turned off & allowed to cool. After
a cool down, the machine will perform normally again. This warning sound is
intended to protect the machine from overheating.
Points to remember
Do not try to extend the
snorkel when the cover is down.
Keep the bag from
blocking the snorkel.
Snorkel must retract
fully before sealing the bag.
Turn off the machine
before starting the next bag.
