Simply hook your SILO SEAL'A up to a 12v battery (use your vehicle or any other machinery/battery that is close by), clamp it onto the open end of your Silo Bag® and adjust the heat setting. Press the red button and wait! You don’t even have to hold it, once in place just wait until the alarm stops, indicating it’s done. Unclamp, move along to the next section and seal again. Repeat until you’ve reached the end of the bag.
