If you are having low or no adhesive flow from your Scotch-Weld EC glue gun it might be because your transport mechanism isn’t working properly. If the transport mechanism does not move freely on the track or the arms of the mechanism don’t open and close freely–clean the transport mechanism. Use a citrus based cleaner to remove any dirt or grime that restricts movement of the transport mechanism. Take the entire transport mechanism off if it needs be to clean. If there is any damage to the transport mechanism replace it with 3M 62-9787-9930-2 EC Transport Mechanism Repair Kit.
