EXTRA LONG
IMPULSE SEALER
WITH CUTTER
1. Set Timer Knob to lowest setting that produces a
good seal for bag thickness. Thicker bags need a
higher setting. (Always start with a low setting and
increase gradually.)
2. Place end of bag under sealing arm and press the arm
down gently but firmly, until the red sealing light is lit.
3. The red light will go out when sealing is complete.
4. When red light goes out, leave the arm down for
2-4 seconds.
5. Use the sliding cutter to cut excess material.
6. Release the arm and remove bag.
CAUTION! Follow all warnings and instructions
marked on the sealer.
1. Unplug sealer from the outlet before cleaning or
changing any parts.
2. Do not rest anything on the power cord. Do not
operate with a damaged power cord or plug.
3. Only turn on sealer when operator is present.
4. Never insert hand or fingers between the Sealing
Jaws unless the unit is unplugged.
5. Never touch the Heating Element with bare hands
while the sealer is plugged in, while in operation or
just finishing operation. The element stays HOT for a
little while after each sealing cycle.
6. Check for worn or broken parts before operating
sealer.
7. Keep the unit clean. Do not use water. Silicone
spray may be used to clean the unit. Make sure the
unit is unplugged before cleaning.
8. When changing the cutting blade, be careful of the
sharp edge. Dispose of old blade in used blade
container.
9. To change the Teflon
®
Tape, cover the entire surface
under the Heating Element with Teflon
®
Tape. Bend
down excess Teflon
®
Tape on both ends to prevent
the Heating Element from breaking and shorting out
the machine.
10. When replacing the fuse, use the exact size, voltage
and amperage.
11. When replacing any parts, be sure to list the exact
locations of the connections and the order of the
different pieces.

OPERATING INSTRUCTIONS
ADDITIONAL INFORMATION
1. The unit can be left plugged in. The unit is OFF unless
the sealing arm is down.
2. Always keep sealer clean and remove any residue
found on the Platform and Teflon Cover. Silicone
spray may be used.
3. When replacing the Heating Elements, always
check the condition of the bottom Teflon Tape.
(See Page 2) A worn Teflon Tape will cause the
Heating Element to short out, which can damage
the element.
4. Occasionally check the Rubber Pressure Pad for
wear or burn. A damaged Pressure Pad affects the
quality of the seal.
5. Turn power OFF and unplug the unit before
replacing any parts.

    Why is the seal wrinkled on my U-Line Food Saver?

      Thomas PattonAug 16, 2025
      If your U-Line Food Saver seal is wrinkled or warped, it might be because the sealing timer is set too high; in this case, lower the timer setting. Also, ensure there's enough cooling time by continuing to press the sealing arm for 1-2 seconds after the sealing light turns off.

      If the power lamp is on but the sealing light doesn't turn on when using your U-Line Food Saver, it could be due to a microswitch issue. Try adjusting the microswitch lever or its position. If that doesn't work, the microswitch might be defective and need replacement.

    Why is my U-Line Food Saver not sealing when both lights are on?
    • P
      Paige RoseAug 22, 2025
      If your U-Line Food Saver isn't sealing, and the power lamp and sealing light are both on, the heating element may be broken, requiring replacement. Another possible cause is a loose spring hook or mounting spring with poor contact; try cleaning or tightening the spring hook connection. Also, check if the terminals of the heating element have good contact; if not, clean the terminals and adjust as needed.

      If your U-Line Food Saver isn't sealing and the power lamp does not turn on, first, check or change the plug to ensure it's properly connected.
