  • This is most likely caused by a blockage in the nozzle, or the content of the cartridge has dried up.
  • Remove and check the nozzle for blockages using the puncture pin attached to the tool.
  • If the cartridge has a blockage, it means the contents have expired and cannot be used.
  • Replacement nozzles are available from Bunnings at no charge.
