IMPORTANT: READ BEFORE USING SAFETY PRECAU

If a manual is missing or you need additional copies, copies are available from Graco at no charge. All Models (See Fig 2) DO NOT install the spray tip in the gun yet. Install an air line filter (H) in the main air line, to remove harmful dirt and moisture from the compressed air supply. Install a bleed–type master air valve (J) close to the pump air inlet, and downstream from the pump air regulator (K). Install a second bleed valve (L) upstream from all other accessories, to isolate the accesso

Use the pump air regulator (K) to control the pump speed and fluid pressure. Always use the lowest pressure necessary to achieve the desired results. Higher pressures waste fluid and cause premature wear of the pump packings and spray tip. Keep the wet–cup filled with Graco Throat Seal Liquid (TSL) or other compatible solvent, to help prolong the packing life. Never allow the pump to run dry of the fluid being pumped. A dry pump will quickly accelerate to a high speed, possibly damaging itself.
