Cleaning out the spray gun and filter:
  1. Unclip the trigger guard from the filter housing by pulling outward from the filter housing. Unscrew the filter housing
  2. Remove the filter from the spray gun housing and clean with the appropriate cleaning solution (warm, soapy water for latex paints, mineral spirits for oil-based materials)
  3. Inspect the filter for holes (see inset, right). Replace if holes are found
  4. Replace the cleaned filter, tapered end first, into the gun housing. The tapered end of the filter must be loaded properly into the gun. Improper assembly will result in a plugged tip or no flow from the gun
