Never use abrasive agents or hard objects andnever spray cleaning agents with a gun. Cleaning the device must not damage it in anyway.Ensure that no electrical component is cleaned with nor even immersed into solvent.Which cleaning agent is used to clean the spray gun depends on which parts of thespray gun have to be cleaned and which product has to be removed. When cleaning thespray gun, only use non-polar cleaning agents to prevent conductive residues on thesurface of the spray gun. Should it however, be necessary to use a polar cleaning agent,all residues of this cleaning agent have to be removed by using a non-conductive andnon-polar cleaning agent, once the cleaning is finished.
