4. Setup
- Unpacking: Carefully remove the machine and all accessories from the packaging. Inspect for any shipping damage.
- Placement: Position the machine on a sturdy, flat, and dry surface. Ensure adequate ventilation around the machine.
- Power Connection: Connect the power supply wire to the machine and then to a suitable 110V/60Hz grounded electrical outlet.
- Conveyor Table Adjustment: The conveying table's height and position can be adjusted to align with your specific bag dimensions and operational needs. Use the adjustment knobs to set the desired height and front/back position.
- Embossing Wheel Installation (Optional): If printing is required, install the embossing wheel and arrange the desired characters (numbers, letters) into the type wheel.
5. Operating Instructions
- Power On: Flip the POWER switch to the ON position.
- Activate Fan and Heater: Turn on the HEATER switch and the FAN switch. The fan helps cool the sealing area after heating.
- Set Temperature: Use the digital Temperature Controller to set the desired sealing temperature. The optimal temperature depends on the bag material and thickness. Start with a lower temperature and gradually increase if the seal is not strong enough. The range is 0 - 400 °C (32 °F - 752 °F).
- Set Sealing Speed: Adjust the SPEED knob to control the conveyor belt's speed. A slower speed generally allows for a stronger seal, while a faster speed increases throughput.
- Test Sealing: Before mass production, perform a test seal on a sample bag to ensure the temperature and speed settings are appropriate for your material.
- Begin Sealing: Place the open end of the bag onto the conveyor belt, guiding it into the sealing mechanism. The machine will automatically feed and seal the bag.
- Adjust Sealing Pressure: The pressure control button can be adjusted to accommodate different bag thicknesses, ensuring a consistent seal.

6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your sealing machine.
- Cleaning: Regularly clean the conveyor belt and sealing area to prevent residue buildup. Use a soft, dry cloth. Ensure the machine is unplugged before cleaning.
- Teflon Belt Inspection: Inspect the Teflon belts for wear and tear. Replace them if they show signs of damage or excessive wear. The machine includes extra Teflon belts for replacement.
- Component Check: Periodically check all screws and connections to ensure they are tight.
- Fuse Replacement: If the machine loses power, check the fuse. Replace it with the provided extra fuse if necessary.
