You can tighten the band to grip the bag better with these simple steps:
Please turn off the machine first and let it cool down. Adjust the tension screws on both sides of the band frame clockwise to tighten the sealing band evenly. You can also slightly adjust the pressure knob of the pressing wheel to increase clamping force. Do not over-tighten to avoid wearing out the band. After adjustment, test with an ordinary bag to check if it holds firmly.
